When it comes to determining a home’s market value, appraisers often face the challenge of comparing properties that don’t look much alike. You might wonder: How can an older brick bungalow be compared to a newer two-story home down the street? The answer lies in a systematic process called adjustments, which ensures that differences between homes are accounted for fairly.

Why Appraisers Need Comparables

Appraisers typically use the sales comparison approach, which relies on analyzing recent sales of comparable homes (“comps”). The problem? Perfect matches rarely exist. Even in the same neighborhood, homes can differ in size, style, age, and condition.

That’s why appraisers make careful adjustments to bring the sales prices of those comps closer in line with the subject property.

Adjusting for Home Differences

Adjustments allow an appraiser to create an “apples-to-apples” comparison. For example, if the comparable home has a renovated kitchen and the subject property does not, the appraiser reduces the comp’s sale price to reflect that difference.

Similarly, if the subject property has a larger lot than the comparable home, the appraiser adds value to the comp’s price. The goal is to estimate what each comparable would have sold for if it were more like the subject property.

Key Factors That Influence Adjustments

Location

Homes in more desirable areas: closer to schools, parks, or transit often sell for more. Appraisers weigh neighborhood differences heavily.

Size and Layout

Square footage matters, but so does layout. An open-concept design may command more value than a segmented floor plan of the same size.

Age and Condition

Newer homes or recently updated properties generally sell for more. Older homes in need of repairs are adjusted downward in comparison.

Upgrades and Amenities

Extra features such as finished basements, fireplaces, or updated bathrooms impact value. Appraisers account for these when comparing homes.

Why Professional Expertise Matters

Appraising is both an art and a science. While market data provides structure, appraisers also rely on experience and professional judgment to balance differences. This expertise ensures a fair and credible opinion of value, whether you’re buying, selling, refinancing, or settling an estate.

Final Thoughts on Comparing Unalike Homes

Even when two houses don’t look alike, appraisers use adjustments to create a level comparison. By analyzing location, size, condition, and amenities, they ensure the valuation reflects the home’s true market worth.
