Frequently Asked Questions
Q1. Why does Fannie Mae require appraisers to follow the ANSI standard?
Valuations of residential property correlate strongly with the dwelling’s square footage.
Our adoption of the ANSIstandard:▪ Provides a professional and defensible method for the appraiser;▪ Allows transparent and repeatable results for consumers of appraisal reports; and▪ Creates alignment across market participants.One key factor in our decision to adopt the ANSI standard is the recent emergence of new technologies, such asphone apps, which can measure houses, generate floor plans, and calculate square footage. In addition,
thedesktop and hybrid appraisal options require a floor plan. Since appraisers are not inspecting the propertypersonally for these appraisals, we anticipate they will commonly receive the floor plan from a third party, so itmakes sense that all parties (including the appraiser) would be using the same standards of measurement. ANSIZ765-2021 is a standard that technologies can build to, other parties (such as real estate agents) can anticipate,and appraisers can create or consume with confidence.
Q20. How should appraisers value finished areas that do not meet the ANSI standard?
Our longstanding policy on adjustment rates has not changed: we require appraisal adjustments to reflect marketreaction. This is explained in the Analysis of Adjustments section of Selling Guide B4-1.3-09, Adjustments toComparable Sales and the corresponding section SB4-1.3-09 in the UAD 3.6 Policy Supplement: “
The expectationis for the appraiser to analyze the market for competitive properties and provide appropriate market-basedadjustments...” It is up to the appraiser to determine the market reaction for nonstandard and noncontinuousfinished areas, which may be greater than, less than, or equal to that of the finished areas.
