An over-improvement is an improvement that is larger or costlier than what is typical for the neighborhood. For example, a 4,000 square foot home located in an area of homes where the typical home is 2,000 square feet may be considered an over-improvement. Furthermore, a home with an in ground pool in an area where pools are not typical may also be considered an over-improvement. The appraiser must comment on over-improvements and indicate their contributory value in the Sales Comparison Approach adjustment grid.
Improvements can represent an over-improvement for the neighborhood, but still be within the neighborhood price range, such as a property with an in-ground swimming pool, a large addition, or an oversized garage in a market that does not demand these kinds of improvements.
The fact that the property is an over-improvement does not necessarily make the property ineligible. However, lenders must review appraisals on properties with over-improvements that may not be acceptable to the typical purchaser to ensure that only the contributory value of the over-improvement is reflected in the appraisal analysis.
