If there are zero comps, their price range is zero to zero,
When completing the One-Unit Housing Trends portion of the Neighborhood section of the appraisal report forms, the trends
must be reflective of those properties deemed to be competitive to the property being appraised. If the neighborhood contains properties that are truly competitive (that is, market participants make no distinction between the properties), then all the properties within the neighborhood would be reflected in the One-Unit Housing Trends section. However, when a segmented or bifurcated market is present, the One-Unit Housing Trends portion must reflect those properties from the same segment of the market as the property being appraised. This ensures that the analysis being performed is based on competitive properties.
For example
if the neighborhood contains a mix of property types not considered competitive by market participants, then a segmented or bifurcated market is present. Additionally, the conclusions reported in this portion of the appraisal will be supported by the analysis contained in the Market Conditions Addendum to the Appraisal Report (Form 1004MC)
the appraiser should also provide commentary on the other segment(s) of the neighborhood when segmentation is present.
Market Conditions Addendum to the Appraisal Report (Form 1004MC)
The lender must confirm that current market conditions are identified and analyzed in the valuation process and described
in the appraisal report.
Form 1004MC is required for all mortgage loans delivered to Fannie Mae with appraisals of one- to four-unit properties. It is
intended to provide the lender with a clear and accurate understanding of the market trends and conditions prevalent in the
subject neighborhood. The conclusions regarding trends that are obtained from the 1004MC Form must be reported in the
Neighborhood section of the report form.
In situations when there is not sufficient data to provide a meaningful analysis for the defined neighborhood, the form must be completed based on the information available, and an explanation must be provided. The lack of data may be an indication of the market conditions. If additional analysis of nearby areas that include competitive properties is performed, it mustbe discussed in the summary/conclusions section of the form. In any scenario, the Neighborhood section of the appraisal report must include the appraiser’s conclusions regarding the housing trends.For additional information concerning Form 1004MC, see B4-1.2-01, Appraisal Report Forms and Exhibits (04/15/2014)
