Minimum Number of Comparable Sales
A minimum of three closed comparables must be reported in the sales comparison approach. Additional comparable sales may be reported to support the opinion of market value provided by the appraiser. The subject property can be used as a fourth comparable sale or as supporting data if it was previously closed. Contract offerings and current listings can be used as supporting data, if appropriate.
In no instance may the appraiser create comparable sales by combining vacant land sales with the contract purchase price of a home (improvements only). While these transactions cannot be used to meet the required minimum three closed comparables, these transactions, which are often completed as part of a construction-to-permanent loan transaction, may be included as additional support with appropriate commentary.
