The sales comparison approach estimates property value by comparing the home with similar recently sold properties.
The sales comparison approach estimates property value by comparing the home with similar recently sold properties and adjusting for meaningful differences.
The sales comparison approach matters because it is one of the most common and influential ways residential properties are valued for mortgage lending.
It also matters because borrowers often hear about Comparable Sales (Comps) without understanding the broader valuation method behind them. This approach is the framework that turns those data points into a supported opinion of value.
The term also matters because it helps explain why one nearby sale is never the whole story. Appraisers do not just point to a house down the street and copy the number. They compare multiple sales with the Subject Property and use Appraisal Adjustment logic for meaningful differences in size, condition, location, and features.
Inside that method, the appraiser may compare Gross Living Area, apply Condition Adjustment, Location Adjustment, or Time Adjustment, and then consider each comp’s Adjusted Sale Price.
Borrowers encounter this approach inside the appraisal process, even if the lender never uses the phrase in a direct conversation.
The term becomes practical when a borrower wants to understand how the appraiser justified the number and why certain nearby sales mattered more than others.
This is especially relevant when a borrower is frustrated by a low value conclusion and wants to understand why the report treated some sales as stronger evidence than others.
A home is valued by reviewing several similar recently sold properties in the same market area, then adjusting for features such as size, condition, lot characteristics, and updates. That is the sales comparison approach at work.
| Step | What the appraiser is trying to learn |
|---|---|
| Select comps | Which recent sales are most similar to the subject property |
| Compare differences | Which size, condition, location, or timing differences matter |
| Adjust sale prices | What each comp indicates after those differences are considered |
| Reconcile value | Which value conclusion is best supported by the overall evidence |
The sales comparison approach differs from Comparable Sales (Comps) because comps are the actual sales data points, while the sales comparison approach is the valuation method built around those points.
It also differs from the Cost Approach, which focuses on land value and replacement cost rather than on recent sales comparisons.
It also differs from the Income Approach, which focuses on income-producing potential rather than owner-occupied market comparison logic.
