How the Appraiser Determines Value
The most common approach for residential appraisals is the sales comparison approach.Fannie Mae Selling Guide B4-1.3-06, Comparable Sales; Uniform Residential Appraisal Report (URAR) Form 1004; Uniform Standards of Professional Appraisal Practice (USPAP), Standards Rule 1-4 that have sold recently in the same market area. Ideal comps are similar in size, age, condition, and location and have sold within the past 3-6 months within 1 mile of the subject property (though these parameters may be relaxed in rural or unique-property situations).
The appraiser then makes dollar adjustments to each comp to account for differences from the subject property. If a comp has an extra bathroom that the subject does not have, the appraiser subtracts the market value of that bathroom from the comp’s sale price. If the subject has a renovated kitchen and the comp does not, the appraiser adds value. These adjustments result in an adjusted sale price for each comp that represents what the comp would have sold for if it were identical to the subject property.
The appraiser reconciles the adjusted values of all comps to arrive at a final opinion of value. This reconciliation gives more weight to the comps that are most similar to the subject and require the fewest adjustments. The result is a single market value figure that represents the appraiser’s professional judgment of what a willing buyer would pay a willing seller for the property in the current market.
How the Reconsideration of Value Process Works
When the borrower or the borrower’s real estate agent believes the appraised value is too low, they can request a reconsideration of value (ROV) through the lender. The ROV is not a direct negotiation with the appraiser; the request goes to the lender, who forwards it to the appraiser through the AMC in compliance with appraiser independence rules.
The ROV request should include specific, factual information: additional comparable sales that the appraiser may not have considered, corrections to factual errors in the report (wrong square footage, missing features, incorrect comp data), or market data that supports a higher value. Emotional arguments or opinions about what the property “should” be worth are not effective. The appraiser reviews the additional data and either revises the value or explains why the original value stands.
ROV requests are successful in some cases, particularly when the appraiser missed a relevant comp or made a factual error. However, appraisers are under no obligation to change their opinion, and many ROV requests are denied. Borrowers should prepare for the possibility that the original value will not change and have a contingency plan.
FHA and VA Appraisal Differences
FHA and VA appraisals have additional requirements beyond establishing market value. FHA appraisals include a property condition assessment based on HUD’s Minimum Property Requirements (MPRs). The appraiser must note any conditions that affect the health and safety of occupants or the structural integrity of the property. Common issues that can delay FHA transactions include For properties built before 1978, FHA appraisals must identify all defective paint surfaces (including cracking, chipping, and peeling), which must be stabilized prior to closing under HUD Handbook 4000.1 and lead-based paint regulations (24 CFR Part 35)., missing handrails on stairs, broken windows, non-functional mechanical systems, and roof deficiencies. The seller must repair these issues before the loan can close, or the loan may not be approved .
VA appraisals similarly include Minimum Property Requirements (MPRs) and must confirm the property meets the VA’s standards for safety, sanitation, and structural soundness. VA appraisals also carry a unique feature: the NOV (Notice of Value). The VA appraisal stays with the property for six months, meaning if the original buyer’s transaction falls through, a subsequent VA buyer can use the same appraisal without ordering a new one .
Both FHA and VA appraisals can be more time-consuming than conventional appraisals due to the condition assessment requirements. Borrowers using these programs should account for potentially longer appraisal timelines and the possibility that repairs may be required before closing.
Desktop and Hybrid Appraisals
In addition to traditional full appraisals, alternative valuation products have become more common. A desktop appraisal is performed entirely from the appraiser’s office using public records, MLS data, photos, and automated valuation models (AVMs) without a physical inspection. A hybrid appraisal combines a third-party property inspection (performed by someone other than the appraiser) with the appraiser’s desk-based analysis.
These alternative products are typically less expensive than full appraisals ($150-$400) and faster to complete. Fannie Mae and Freddie Mac allow them on certain transactions that meet specific eligibility criteria, generally lower-risk loans where the property data is well-established. Not all lenders offer these options, and they may not be suitable for properties that need a thorough condition assessment .
