How Appraisers Select Comparable Sales for a Home

Want to see what you qualify for? I can run your numbers and give you a clear answer quickly.

How Appraisers Select Comparable Sales

Appraisers select comparable sales by identifying recently sold properties that represent the alternatives a typical buyer would have considered when purchasing the subject property.

The closest home is not always the best comparable.

Neither is:

Most recent sale
Same-size home
Highest-priced sale
Lowest-priced sale
House in the same subdivision
Property with the closest price per square foot

A strong comparable usually competes with the subject across several important characteristics, including:

Location
Sale date
Property type
Design
Gross living area
Condition
Construction quality
Site characteristics
View
Amenities
Functional utility

The appraiser’s job is not to find three homes that prove the contract price.

The job is to analyze the market and select the sales that best help answer:

What would a typical buyer likely have paid for this property as of the appraisal’s effective date?

What Is a Comparable Sale?

A comparable sale—often called a “comp”—is a property transaction used to help estimate the market value of another property.

The property being appraised is called the subject property.

A comparable sale should provide meaningful evidence of how buyers and sellers react to properties similar to the subject.

For example, a useful comparable for a recently renovated 2,500-square-foot home might share several characteristics:

Same competitive market area
Similar school district
Similar age
Similar design
Similar lot
Similar condition
Similar renovation level
Similar garage
Recent arm’s-length sale

A property does not need to be identical to be comparable.

Nearly every comparable requires some analysis of its differences from the subject.

How Many Comparable Sales Are Required?

A standard residential appraisal commonly includes at least three closed comparable sales in the sales-comparison approach.

The appraiser may also include:

Additional closed sales
Pending sales
Active listings
Prior sales
Competing properties
Builder sales

Fannie Mae generally requires the appraisal report to contain a minimum of three closed comparable sales and allows additional sales when they help support the value conclusion. Fannie Mae comparable-sale requirements

Three is a minimum for many standard appraisal forms—not a guarantee that three sales are always sufficient.

A complex property may require additional evidence.

Appraisers Begin With the Subject Property

Comparable selection starts with understanding the subject.

The appraiser identifies characteristics such as:

Property type
Location
Neighborhood
Gross living area
Site size
Age
Design
Construction quality
Condition
Bedroom and bathroom count
Garage
Pool
View
Renovations
Outbuildings
Functional layout
Accessory dwelling unit
Zoning
Highest and best use

The appraiser cannot select meaningful comparables without first understanding what buyers are comparing the subject against.

The Competitive Market Matters More Than a Radius

Appraisers consider the market in which the subject competes.

A competitive market area may be defined by:

Subdivision
Neighborhood
School district
City
Rural community
Price segment
Property type
Commuting pattern
Natural or artificial boundaries
Buyer preferences

A comparable one mile away may be inappropriate if it is:

Across a major highway
In a different school district
In a superior gated community
In an inferior flood area
Subject to different zoning
In a different buyer market

A comparable five miles away may be appropriate when buyers routinely consider both locations.

Neighborhood Boundaries

Appraisers may analyze boundaries created by:

Highways
Railroads
Rivers
School zones
Municipal boundaries
Gated entrances
Commercial corridors
Topography
Waterfront
Master-planned development
Rural land-use patterns

Crossing a boundary does not automatically invalidate a comparable.

The appraiser should explain why a sale outside the immediate neighborhood competes with the subject.

Buyer Behavior Drives Comparable Selection

The central question is not:

Which homes look close on a map?

It is:

Which properties would the same typical buyer seriously consider?

A buyer searching for:

Downtown condominium
Five-acre horse property
Historic home
New suburban construction
Luxury estate
Waterfront home
Barndominium
Manufactured home

will consider a different set of alternatives.

The comparable search should reflect that buyer behavior.

Sale Date

Recent sales are usually preferable because they reflect market conditions near the effective date of the appraisal.

However, an older highly similar sale may be more useful than a recent property that is materially different.

The appraiser considers:

Contract date
Closing date
Market direction
Rate environment
Inventory
Seller concessions
Seasonal changes
Price trend
Property type

A sale does not become unusable merely because it is more than six months old.

The appraiser should explain the selection and apply a supported market-condition adjustment when necessary.

There Is No Universal Six-Month Rule

Borrowers and real-estate professionals often hear that every comparable must have sold within six months.

That is not a universal appraisal rule.

Appraisers generally prefer recent sales, but may use older sales when:

Property is unique
Market has limited activity
Older sale is more physically similar
Recent sales are in different markets
Rural property is being appraised
Appropriate market adjustments can be supported

A two-month-old sale is not automatically better than a ten-month-old sale.

Similarity and market relevance both matter.

Property Type

Comparable properties should generally reflect the same basic property category.

Examples include:

Detached single-family home
Attached townhouse
Condominium
Cooperative
Manufactured home
Two-to-four-unit property
Rural residential property
Planned-unit development
High-rise unit
New construction
Historic residence

A condominium is not usually a direct substitute for a detached home.

A manufactured home may not compete directly with a site-built property.

The appraiser may use a different property type only when market evidence shows that buyers consider it a true alternative and the difference can be analyzed credibly.

Architectural Design

Design can influence:

Buyer demand
Functional utility
Construction cost
Marketability
Living-area distribution

Examples include:

One-story
Two-story
Split-level
Ranch
Colonial
Contemporary
Mediterranean
Victorian
Barndominium
Custom estate

A 3,000-square-foot one-story home may not compete equally with a 3,000-square-foot three-story home.

Buyers may assign value to layout, stair requirements, bedroom placement, ceiling height, and indoor-outdoor flow.

Gross Living Area

Appraisers compare above-grade finished living area under the applicable measurement and reporting standards.

They may separately analyze:

Above-grade living area
Below-grade area
Finished basement
Garage
Porch
Detached guest quarters
Accessory dwelling unit
Unfinished space

Two properties can have similar total enclosed area but different recognized gross living area.

For example:

Subject: 2,400 square feet above grade
Comparable: 1,900 square feet above grade plus 500-square-foot finished basement

Those properties are not necessarily equivalent.

Is There a Required Size Range?

There is no universal rule stating that every comparable must be within exactly:

10% of subject size
15% of subject size
20% of subject size

Closer size similarity is generally preferable because it reduces the need for large adjustments.

A larger difference may be acceptable when:

Market has limited sales
Property is unique
Sale is otherwise highly comparable
Size adjustment is supported
Appraiser explains the selection

The appraiser should not select a poor nearby sale merely to satisfy an arbitrary percentage.

Bedroom and Bathroom Count

Bedroom and bathroom differences matter when the market reacts to them.

The appraiser may consider:

Total bedrooms
Primary bedroom location
Full bathrooms
Half bathrooms
En-suite bathrooms
Bedroom functionality
Legal or code issues
Septic capacity
Below-grade bedrooms

The market may place little additional value on a fifth bedroom in one neighborhood and substantial value on it in another.

Adjustments should reflect local buyer behavior—not a universal price per bedroom.

Construction Quality

Construction quality considers features such as:

Materials
Workmanship
Architectural detail
Customization
Finishes
Structural complexity
Cabinetry
Flooring
Windows
Exterior materials
Mechanical systems

A custom luxury home should not be compared casually with a production-built home simply because both have similar size and age.

The appraiser may need to expand distance or sale date to find properties of similar quality.

Property Condition

Condition reflects the property’s physical state and level of updating.

The appraiser may consider:

Deferred maintenance
Renovation
Kitchen and bathroom updates
Roof
HVAC
Windows
Flooring
Exterior condition
Structural issues
Effective age
Overall market appeal

A fully renovated home and an original-condition home in the same subdivision may sell at materially different prices.

The appraiser should analyze whether the market supports a condition adjustment.

Renovation Level

The word “renovated” can describe very different work.

A renovation may involve:

Cosmetic paint and flooring
New kitchen
New bathrooms
Electrical replacement
Plumbing replacement
Roof
Windows
Structural changes
Addition
Complete reconstruction

The appraiser considers how buyers respond to the completed work.

Renovation cost does not automatically equal contributory value.

A seller may spend $100,000 on improvements that contribute less—or occasionally more—than $100,000 in the market.

Effective Age Versus Actual Age

Two homes built in the same year may have different market appeal because one has been substantially renovated.

The appraiser may consider effective age, which reflects the property’s condition and utility relative to its chronological age.

A well-maintained 40-year-old home may compete more closely with newer properties than a neglected home built the same year.

Site Size

Lot size can affect value, but the relationship is rarely linear.

The appraiser considers:

Total area
Usable area
Shape
Topography
Access
Utilities
Floodplain
View
Road frontage
Privacy
Development potential
Restrictions
Highest and best use

A one-acre lot is not necessarily worth twice as much as a half-acre lot.

The additional land may provide declining marginal utility.

Acreage Properties

Comparable selection becomes more complex when a residential property includes significant acreage.

The appraiser may evaluate:

Residential character
Agricultural use
Usable acreage
Outbuildings
Water features
Fencing
Barns
Soil
Topography
Multiple parcels
Excess or surplus land

A nearby subdivision home on one-quarter acre may be geographically close but economically incomparable to a ten-acre residence.

See Mortgage Financing for Acreage Properties in Texas.

View and Location Influence

A view can materially affect value.

Examples include:

Lake
Hill Country
Golf course
Downtown skyline
Greenbelt
Canyon
Ocean
Mountain
Park

Location can also create negative influences:

Highway
Commercial property
Railroad
Airport
Power line
Industrial use
Busy road
Floodplain

The appraiser should select sales with similar influences when possible.

When not possible, supported adjustments may be required.

School District

School-district boundaries can affect buyer behavior and sale prices.

A property physically near the subject may be in a different district with:

Different demand
Different tax rate
Different reputation
Different attendance zone
Different resale market

An appraiser may cross school boundaries when market evidence supports doing so, but should consider whether typical buyers view the areas as substitutes.

Pools

A pool can affect value differently depending on:

Climate
Neighborhood expectations
Pool condition
Size
Design
Maintenance cost
Buyer preferences
Availability among competing properties

In some Texas markets, a pool may contribute meaningful value.

In other segments, it may contribute less than its construction cost or have mixed market appeal.

The appraiser should use pool comparables when available and derive adjustments from market evidence.

Garages, Workshops, and Outbuildings

Appraisers may consider:

Garage capacity
Attached or detached design
Carport
Workshop
Barn
Storage building
RV garage
Guest house
Accessory dwelling unit

The structure’s replacement cost does not automatically establish market contribution.

A large workshop may be highly desirable in an acreage market but provide limited contribution in a neighborhood where buyers do not need one.

Functional Utility

Properties with similar size can have different functionality.

The appraiser may analyze:

Floor plan
Bedroom placement
Ceiling height
Traffic flow
Natural light
Storage
Access
Obsolescence
Unusual additions
Lack of privacy
Low ceiling areas
Walk-through bedrooms

A poorly designed 3,000-square-foot home may not compete with a well-designed home of the same size.

Highest and Best Use

Comparable selection should reflect the property’s highest and best use.

A property’s current use may differ from the use that is:

Legally permissible
Physically possible
Financially feasible
Maximally productive

For example, a residence in an increasingly commercial corridor may require additional analysis.

A property with multiple units or developable land may not compete with ordinary single-family homes.

Closed Sale Verification

The appraiser should verify important transaction information.

Sources may include:

Multiple listing service
Public records
Listing agent
Selling agent
Buyer
Seller
Builder
Title records
Data services

The appraiser may investigate:

Sale price
Contract date
Closing date
Concessions
Relationship between parties
Property condition
Renovations
Personal property
Unusual financing
Whether sale was arm’s length

Incomplete or inaccurate sale information can distort the analysis.

Arm’s-Length Transactions

An arm’s-length sale generally involves independent parties acting in their own interests without an unusual relationship.

Potential non-arm’s-length transactions include:

Family sale
Employer-to-employee sale
Business-partner sale
Estate transaction
Related-party sale
Distressed transfer
Builder affiliate transaction

A non-arm’s-length sale is not automatically unusable.

The appraiser must determine whether the price reflects normal market behavior.

Distressed Sales

A foreclosure, short sale, or estate sale may sell below typical market levels.

The appraiser may still use it when:

Distressed sales compete with the subject
They influence local values
Market contains many such transactions
Property condition is comparable
Transaction differences can be analyzed

An appraiser should not automatically exclude every distressed sale.

The key is whether the sale reflects the subject’s competitive market.

Seller Concessions

Seller-paid costs may affect the effective price of a comparable.

Possible concessions include:

Closing costs
Discount points
Rate buydown
Prepaid expenses
HOA payments
Repair allowances
Personal property
Builder incentives

The appraiser should determine whether the concession influenced the sale price.

Freddie Mac explains that appraisers should analyze the market’s reaction to financing and sales concessions rather than automatically adjusting dollar for dollar. Freddie Mac guidance on financing and sales concessions

Concessions Are Not Always Adjusted Dollar for Dollar

Suppose a comparable sold for $500,000 with a $15,000 seller credit.

The correct adjustment is not automatically negative $15,000.

The appraiser should determine whether:

Price was increased to cover the credit
Similar concessions are common
Buyer would have paid the same price without it
Concession exceeded market norms
Financing terms affected buyer behavior

The market impact could be:

Full amount
Partial amount
No measurable amount
Another supported figure

Personal Property

A transaction may include:

Furniture
Appliances
Equipment
Farm machinery
Golf cart
Boat
Artwork
Livestock-related equipment

Personal property is not part of the real property’s appraised value.

The appraiser may need to determine whether the reported sale price includes non-realty items and adjust or analyze the transaction appropriately.

Builder Sales

New-construction comparables may involve:

Base price
Lot premium
Design upgrades
Closing-cost incentives
Rate buydown
Preferred-lender credit
Non-realty items

The appraiser should analyze the complete transaction.

A builder sale with substantial incentives may not be equivalent to a resale without concessions.

Builder cost and list price do not independently establish market value.

Off-Market and Private Sales

An off-market sale may provide useful evidence when:

Transaction is verified
Property was adequately exposed or circumstances are understood
Parties acted independently
Condition and concessions are known
Sale reflects market behavior

Limited market exposure can affect reliability.

The appraiser should explain why the transaction is meaningful.

Prior Sale of the Subject

The appraiser may analyze prior sales or transfers of the subject property.

This can help identify:

Recent acquisition
Renovation
Rapid price increase
Non-arm’s-length transfer
Flip transaction
Market appreciation
Title change

A prior sale does not automatically establish current value.

The appraiser must explain significant changes between the prior transaction and current contract.

Pending Sales

Pending sales can help show current market direction.

They may be particularly relevant when:

Market is changing rapidly
Closed sales are older
Inventory is limited
Subject received multiple offers
New phase is selling at higher prices

The final contract price may be unavailable or confidential.

A pending sale generally supports—not replaces—closed sales.

Active Listings

Active listings help show the subject’s current competition and upper value limits.

A listing represents what a seller is asking, not what a buyer has agreed to pay.

The appraiser may compare:

List price
Days on market
Price reductions
Condition
Seller concessions
Competing inventory

A market with many lower-priced listings can limit support for a higher appraisal value.

Expired and Withdrawn Listings

Expired or withdrawn listings may show that buyers rejected a particular price.

The appraiser may analyze:

Original list price
Final list price
Days on market
Property condition
Reason for withdrawal
Whether property later sold

These listings can provide context about market resistance.

Market Conditions

Comparable selection should reflect market conditions as of the effective date.

The appraiser may consider:

Rising prices
Stable prices
Declining prices
Inventory
Marketing time
Sale-to-list ratios
Concessions
Interest-rate changes
Buyer demand
Seasonal patterns
New construction

A comparable from an earlier period may require a market-condition adjustment.

Time Adjustments

A time adjustment reflects a supported change in market value between:

Comparable’s contract date
Appraisal’s effective date

The adjustment should be based on relevant evidence, such as:

Paired sales
Repeat sales
Market-segment trend
Statistical analysis
Local price index
Builder pricing
Other credible market data

A national appreciation rate may not reflect the subject’s neighborhood or property type.

How Appraisers Search for Comparables

An appraiser may begin with a broad search and then refine it using:

Geographic area
Sale date
Property type
Living area
Age
Site size
Design
Condition
Quality
Amenities
View
Price range

The appraiser should not begin with the contract price and search only for homes that justify it.

The final comparable set should reflect the most relevant market evidence, including evidence below and above the likely value when available.

Bracketing

Bracketing means selecting comparables that are both superior and inferior to the subject for important characteristics.

The appraiser may try to bracket:

Living area
Site size
Age
Condition
Quality
Sale price
View
Amenities

For example, if the subject has 2,500 square feet, the appraisal might include:

2,300-square-foot sale
2,480-square-foot sale
2,700-square-foot sale

Perfect bracketing is not always possible.

The appraiser should explain market limitations when important characteristics cannot be bracketed.

Why the Highest-Priced Sale May Not Be Used

A higher-priced property may be excluded because it is:

Larger
Newer
More renovated
On a better lot
In a superior neighborhood
In a different school district
Custom built
On the waterfront
Not an arm’s-length sale
Sold with unusual terms

The fact that it supports the desired value does not make it comparable.

Why the Closest Sale May Not Be Used

The closest sale may differ because it:

Is a condominium
Is in another subdivision
Has commercial influence
Has inferior condition
Is much smaller
Sold under distress
Has different zoning
Is across a major boundary
Appeals to a different buyer

Distance is only one component of relevance.

Why the Most Recent Sale May Not Be Used

A very recent sale may be:

Different property type
Poor-quality match
New construction
Heavily renovated
Distressed
Subject to large concessions
Outside the competitive market
Missing reliable data

A slightly older, more similar sale may provide better evidence.

Why the Most Similar Home May Still Be Excluded

A physically similar home may have an unreliable transaction.

For example:

Family transfer
Foreclosure
Undisclosed concession
Private sale with limited exposure
Personal property included
Title problem
Unusual financing
Sale not verified

Physical similarity does not overcome unreliable transaction data.

Comparable Selection Versus Adjustments

Selecting comparables and adjusting comparables are two separate steps.

First, the appraiser selects relevant market transactions.

Then the appraiser analyzes differences between each comparable and the subject.

Potential adjustments may involve:

Market conditions
Location
Site
View
Design
Quality
Condition
Living area
Bedrooms
Bathrooms
Basement
Garage
Pool
Outbuildings
Concessions

A weak comparable cannot always be made reliable through a large number of adjustments.

The best practice is generally to select the most comparable sales first, then adjust for remaining differences.

How Adjustments Work

Adjustments are applied to comparable-sale prices—not to the subject.

If a comparable is inferior to the subject, the appraiser may adjust the comparable upward.

If a comparable is superior, the appraiser may adjust it downward.

Example: Inferior Comparable

Comparable sale price: $500,000
Comparable lacks a feature the subject has
Supported contributory-value adjustment: +$20,000

Adjusted indication: $$ 500, 000 + $ 20, 000 = $ 520, 000$

Example: Superior Comparable

Comparable sale price: $540,000
Comparable has a superior feature
Supported adjustment: −$15,000

Adjusted indication: $$ 540, 000 - $ 15, 000 = $ 525, 000$

The appraiser then reconciles the adjusted indications.

Adjustments Should Reflect Market Reaction

An adjustment should reflect how buyers react to a feature—not necessarily its construction cost.

For example:

Pool cost: $90,000
Supported market contribution: $40,000

The appraiser may use a $40,000 adjustment when market evidence supports it.

Cost and value answer different questions.

Paired-Sales Analysis

Paired-sales analysis compares properties that are similar except for one meaningful characteristic.

If two otherwise similar homes sell for different amounts and the primary difference is a pool, the price difference may help support a pool adjustment.

Perfect pairs are rare.

The appraiser may use multiple data points and professional analysis to isolate market reaction.

Qualitative Analysis

Not every difference can be measured reliably with a precise dollar adjustment.

An appraiser may use qualitative analysis to determine whether a property is:

Superior
Similar
Inferior

This may be appropriate for:

View
Architectural appeal
Privacy
Complex location influences
Rare amenities
Unique quality

The appraiser must still provide a credible and understandable analysis.

Net and Gross Adjustments

Adjustment totals can indicate how different a comparable is from the subject.

Net adjustment reflects the mathematical balance after positive and negative adjustments.
Gross adjustment reflects the total magnitude of all adjustments without canceling them against one another.

A small net adjustment can be misleading when large positive and negative adjustments offset each other.

For example:

Positive adjustments: $80,000
Negative adjustments: $75,000
Net adjustment: $5,000
Gross adjustment: $155,000

The comparable required substantial analysis despite the small net result.

There Are No Universal 15%, 25%, or 10% Rules

Older appraisal discussions sometimes refer to rigid adjustment guidelines such as:

10% line adjustment
15% net adjustment
25% gross adjustment

These are not universal automatic eligibility limits.

Large adjustments may indicate that a comparable is less similar, but they do not automatically make the appraisal unacceptable.

Fannie Mae requires adjustments to reflect market reaction and expects the appraiser to explain the selection and analysis when comparables differ materially. Fannie Mae adjustment requirements

Price Per Square Foot

Price per square foot can help identify broad patterns, but it does not control comparable selection or value.

A property’s price reflects:

Land
Location
Quality
Condition
Design
Garage
Pool
View
Amenities
Functional utility

Smaller homes often sell for more per square foot because fixed components such as land and kitchen value are spread across fewer square feet.

The appraiser should not simply multiply subject size by the average price per square foot.

Reconciliation

After adjusting and analyzing the comparable sales, the appraiser reconciles the indications into a final opinion of value.

Reconciliation is not necessarily a simple average.

Suppose adjusted indications are:

Comparable 1: $505,000
Comparable 2: $520,000
Comparable 3: $535,000

The arithmetic average is: $($ 505, 000 + $ 520, 000 + $ 535, 000) \div 3 = $ 520, 000$

The appraiser is not required to conclude $520,000.

Greater weight may be given to a comparable that is:

More recent
Closer
More similar
Better verified
Less adjusted
More representative of buyer behavior

Weighting Comparable Sales

The appraisal may give greater weight to one or two sales.

A heavily weighted comparable might:

Be in the same subdivision
Have the same model
Have similar condition
Have a similar lot
Require fewer adjustments
Have reliable transaction data

The appraiser should explain the reconciliation sufficiently for the reader to understand the conclusion.

Contract Price

The appraiser analyzes the purchase contract and considers the contract price.

The contract can provide useful market evidence when:

Property was exposed to the market
Buyer and seller are unrelated
Negotiations were typical
Multiple offers existed
Concessions are understood

The appraiser is not required to match the contract price.

The contract may reflect:

Overbidding
Personal motivation
Appraisal-gap strategy
Non-realty items
Seller concessions
Unusual terms
Limited market exposure

Appraised Value Above the Contract Price

An appraisal may conclude above the purchase price.

For most purchase mortgages, the lender still calculates LTV using the lower of:

Purchase price
Appraised value

The higher appraisal generally does not allow the buyer to treat the difference as additional down payment.

For example:

Purchase price: $400,000
Appraised value: $420,000
Loan amount: $360,000

Purchase LTV is generally based on $400,000: $$ 360, 000 \div $ 400, 000 = 90 %$

The buyer does not generally receive a 85.7% purchase LTV merely because the appraisal is higher.

Appraised Value Below the Contract Price

A low appraisal may affect:

Maximum loan amount
Required cash
Mortgage insurance
Interest-rate pricing
Loan-to-value ratio
Contract rights
Seller negotiations

The buyer may consider:

Reconsideration of value
Price reduction
Appraisal gap
Different loan structure
Applicable termination rights

See Should You Pay More Than the Appraised Value?

How Appraisers Select Comps for Conventional Loans

Conventional appraisers follow applicable appraisal standards and the requirements of the agency or investor.

The lender reviews whether the appraisal includes:

Adequate closed sales
Appropriate market-area analysis
Supported adjustments
Accurate subject description
Reasonable reconciliation
Acceptable property eligibility

Automated collateral tools may also analyze the comparable selection and value risk.

FHA Comparable Selection

An FHA appraisal evaluates:

Market value
Property acceptability
FHA requirements

The appraiser selects market comparables while also reporting property conditions that may affect FHA eligibility.

FHA does not require the appraiser to select sales that match the contract price.

A high value also cannot cure an unacceptable property condition.

VA Comparable Selection

A VA appraiser estimates reasonable value and evaluates applicable minimum property requirements.

The appraiser may invoke the Tidewater process when it appears that value may be below the contract price.

That allows the designated contact to submit additional market evidence before the appraisal is completed.

After completion, an interested party may request a VA Reconsideration of Value through the lender when better evidence or appraisal errors exist.

VA provides current training on comparable analysis, Tidewater, and ROV through its fee-appraiser training series. VA appraisal training

USDA Comparable Selection

USDA appraisal analysis also considers:

Market value
Property condition
Program eligibility
Rural market characteristics

Rural properties may require:

Older sales
Wider search area
Larger adjustments
Detailed explanation
Consideration of acreage and outbuildings

The absence of three nearly identical nearby sales does not automatically make the property ineligible.

Jumbo Appraisals

Jumbo lenders may impose additional appraisal requirements such as:

Second appraisal
Desk review
Field review
Automated valuation review
Additional comparable sales
Appraisal committee review
Lower of two values

High-value and unique homes may require a wider geographic and historical search.

The lender may place greater scrutiny on:

Comparable quality
Large adjustments
Marketability
Luxury features
Site value
Declining markets

Condominiums

Condominium comparable selection may consider:

Same project
Same phase
Floor level
View
Unit size
Parking
Storage
Balcony
Condition
HOA dues
Amenities
Special assessments

A same-project sale is often valuable because it reflects the project’s specific market.

However, it may be inappropriate if it differs materially in view, floor, condition, or unit type.

Manufactured Homes

Manufactured-home appraisals generally require comparables that appropriately reflect manufactured housing.

The appraiser may consider:

Construction type
Age
Size
Foundation
Land ownership
Site size
Permanent attachment
Condition
Local market acceptance

A nearby site-built home does not automatically represent the same market.

Program-specific comparable requirements may apply.

Rural Homes and Barndominiums

Rural and nontraditional homes may have limited comparable sales.

The appraiser may need to use:

Wider search area
Older sales
Different but competitive designs
Land analysis
Cost approach
Detailed market explanation

The appraisal should explain why the selected properties represent the best available evidence.

How Realtors Can Help Before the Appraisal

A Realtor may provide a concise appraisal package containing:

Recent closed sales
Pending sales
Improvement list
Multiple-offer information
Survey
Floor plan
Permits
Relevant contract details

The information should be provided through an appropriate, noncoercive process.

The Realtor should not:

Demand a value
Exclude lower sales
Pressure the appraiser
Misrepresent improvements
Provide unreliable data

Helpful market information is permitted.

Improper influence is not.

How Homeowners Can Help on a Refinance

A homeowner can prepare:

Improvement list
Completion dates
Permits
Contractor invoices
Before-and-after photographs
Survey
Floor plan
Information about additions
Access instructions

The homeowner should allow the appraiser to perform an independent analysis.

Declaring what the home “must be worth” is less helpful than providing accurate property information.

Challenging Comparable Selection

A borrower may challenge an appraisal when the selected sales appear inappropriate.

A strong challenge explains:

Which comparable is problematic
Why it does not compete with the subject
Which factual detail is incorrect
Which better sale was available
Why the proposed sale is superior
How the issue affects value

Weak challenge:

Comparable 2 is too low.

Stronger challenge:

Comparable 2 is located outside the subject’s school district, backs to a commercial property, and was in original condition. The proposed sale at 125 Oak Drive closed two weeks earlier, is within the subject subdivision, has similar renovation quality, and is within 4% of the subject’s living area.

Reconsideration of Value

A reconsideration of value should focus on:

Better comparable sales
Factual corrections
Unsupported adjustments
Missing improvements
Market-trend evidence
Transaction errors

It should not rely primarily on:

Emotional appeal
Seller’s desired proceeds
Construction cost
Contract deadline
Loan amount needed
Unsupported price-per-square-foot calculation

See How to Challenge a Low Mortgage Appraisal.

Why a Suggested Comparable May Be Rejected

An appraiser may reject a proposed sale because:

It is outside the competitive market
Sale is too old
Property type differs
Condition is superior
Quality is superior
Transaction was not arm’s length
Concessions were substantial
Sale could not be verified
Property has a superior view
Site is not comparable
Buyer pool differs

A credible appraisal should explain significant selection decisions sufficiently.

What Can Go Wrong?

Appraiser Uses Only Nearby Sales

The closest properties do not represent the subject’s buyer market.

Appraiser Expands Too Far Without Explanation

Comparable prices may be inflated by financing or seller contributions.

Listings Are Treated Like Closed Sales

Asking price is mistaken for confirmed value.

Price Per Square Foot Controls the Analysis

Important differences in land, condition, and quality are ignored.

Appraiser Uses Arbitrary Adjustments

Dollar amounts lack market support.

Highly Adjusted Sales Receive the Most Weight

More comparable sales are available.

Subject Facts Are Incorrect

Living area, condition, site, or amenities are misreported.

Reconciliation Is Unexplained

Final value does not follow logically from adjusted indications.

Questions Worth Asking

When reviewing comparable sales, ask:

Are the sales in the same competitive market?
Would the same buyer consider them?
How recent are they?
Are they the same property type?
Is gross living area comparable?
Are condition and quality similar?
Are lot and view characteristics similar?
Were concessions verified?
Were transactions arm’s length?
Are time adjustments supported?
Do the sales bracket important characteristics?
Were closer or more similar sales omitted?
Are adjustments based on market reaction?
Which sales received the greatest weight?
Does the final value follow from the analysis?

Common Misconceptions

“Comps Must Be Within One Mile”

There is no universal one-mile rule. Competitive market boundaries and buyer behavior matter.

“Comps Must Have Sold Within Six Months”

Recent sales are preferred, but older highly comparable sales may be appropriate.

“Comps Must Be Within 10% of the Subject’s Size”

Closer similarity is helpful, but no universal 10% requirement applies to every appraisal.

“The Highest Sale Is the Best Comp”

A high sale may be superior in location, quality, condition, or size.

“The Closest Sale Must Be Used”

The nearest sale may appeal to a different buyer.

“Price Per Square Foot Determines Value”

Price per square foot does not fully account for land, quality, condition, design, and amenities.

“Every Concession Is Adjusted Dollar for Dollar”

The adjustment should reflect market impact.

“Renovation Cost Equals Value”

The market may contribute more or less than construction cost.

“The Final Value Is the Average of the Comps”

The appraiser reconciles the indications and may weight the strongest sales more heavily.

“The Contract Price Determines Comparable Selection”

The appraiser must perform an independent market analysis.

Real Lender Perspective

A good comparable is not the sale with the smallest geographic distance, closest square footage, or highest price.

It is the sale that most credibly represents what the subject’s likely buyer would have considered.

The appraiser should work through a sequence:

Understand the subject.
Define the competitive market.
Identify likely buyer alternatives.
Search recent closed transactions.
Verify sale terms.
Compare physical and locational characteristics.
Select the strongest evidence.
Adjust for meaningful differences.
Analyze listings and pending sales.
Reconcile the indications.

When a value appears unsupported, the borrower should reverse that process:

Verify subject facts.
Examine market boundaries.
Review each selected sale.
Identify better alternatives.
Document why they are superior.
Request reconsideration through the lender.

The goal is not to find sales that produce the desired number.

It is to identify the market evidence that most accurately explains the subject’s value.

Final Thoughts

Appraisers select comparable sales by evaluating which properties represent realistic alternatives to the subject.

The strongest comparables generally share meaningful similarities in:

Market area
Sale date
Property type
Size
Design
Quality
Condition
Site
View
Amenities

No single rule determines the best sale.

A nearby property can be a poor comparable.

An older or more distant sale can be highly relevant.

After selecting the best available transactions, the appraiser analyzes differences, applies supported adjustments, and reconciles the evidence into a final opinion of value.

Understanding that process helps borrowers and Realtors evaluate an appraisal intelligently—and build a much stronger reconsideration request when the wrong comparable sales were selected.
