Your appraisal is a form. Here is what each part of it means.
Most residential appraisals come back on the same document, Fannie Mae Form 1004. It looks dense because it is built for underwriters, not for the person paying for it. It has eight sections, and each one answers a single question.
Read them in order and you can check the report yourself.
Eight sections, in the order they appear
The notes beside each section flag the parts people misread most.
Subject
Identifies the property, the owner of record, the legal description, the assessor parcel number and who ordered the report. It also states the intended use and the intended user, which is almost always the lender.
Contract
On a purchase, the appraiser records the contract price, the date and whether any seller concessions were involved. On a refinance this section is usually marked as not applicable.
Neighborhood
Describes the surrounding market. Boundaries, whether values are rising, stable or declining, typical marketing time and the usual price range for the area.
Site
The lot itself. Size, shape, zoning, utilities, easements and whether the site sits in a special flood hazard area.
Improvements
The structure. Age, design, foundation, room count, condition and quality ratings, updates, and the gross living area.
Sales comparison approach
Residential reports lean on this section most. Recent sales of similar nearby property sit in columns next to yours, and the appraiser adds or subtracts value for each difference.
Reconciliation
The appraiser explains which comparable sales carried the most weight and why, then states the final opinion of value and its effective date.
Certification and addenda
Signatures, license number and expiry, the assumptions the report rests on, photographs, the sketch, the location map and any extra commentary.
What you can do about it
You cannot appeal an opinion. You can supply facts the appraiser did not have.
The formal route is a Reconsideration of Value, usually shortened to an ROV. It goes through the lender, not directly to the appraiser, because appraiser independence rules keep you from contacting them about value.
An ROV works when you bring something specific: closed sales the report missed, a wrong room count or square footage, or a permit for work the report left out. It does not work when the only argument is that the number feels low.
Get the facts together first, then send them through whoever ordered the appraisal.
When you want an appraisal of your own
Sometimes you want your own opinion of value, say before listing, after a renovation or while settling an estate.
