What is Sales Comparison?

Appraisers typically rely on the sales comparison approach to value these types of items. Appraisers get to know the neighborhoods in which they work. They understand the value of certain features to the residents of that area. They know the traffic patterns, the school zones, the busy throughways; and they use this information to determine which attributes of a property will make a difference in the value. Then, the appraiser researches recent sales in the vicinity and finds properties which are ''comparable'' to the subject being appraised. The sales prices of these properties are used as a basis to begin the sales comparison approach.

Using knowledge of the value of certain items such as square footage, extra bathrooms, custom finishings, fireplaces or a view (just to name a few), the appraiser adjusts the comparable properties to more accurately reflect the subject property. For example, if the comparable property has a fireplace and the subject does not, the appraiser may deduct the value of a fireplace from the sales price of the comparable home. If the subject property has an extra half-bathroom and the comparable does not, the appraiser might add a certain amount to the comparable property.

In the case of income producing properties - rental houses for example - the appraiser may use a third approach to valuing the property. In this case, the amount of income the property produces is used to arrive at the current value of those revenues over the foreseeable future.
