Home Appraisal vs Inspection: What an Appraiser Checks

By the time the appraiser pulls out of the driveway, a fixed list of things has to exist before the appraisal can be written. Photographs of the kitchen. Of every bathroom. Of every main living area. Of every room below grade, finished and unfinished alike. Of the front of the house, the back of the house, and the street it sits on. A sketch carrying exterior dimensions written to the nearest tenth of a foot. Photographs of any physical deterioration, and of any recent remodeling. That list is not the appraiser's preference — it is the exhibit table in Fannie Mae Selling Guide B4-1.2-01, version dated 09/03/2025 and read on 21 August 2026.

Then the appraiser drives to at least three other addresses and photographs the front of each one from the street. Your house is one stop of four or more that day, and the visit inside it exists to fill in a grid whose other columns are already chosen.

Nothing on that list is a condition assessment, and the form says so in its own words. Under INTENDED USER on page 4 of Fannie Mae Form 1004: "The intended user of this appraisal report is the lender/client." You paid for it. You are entitled to a copy. You are not who it was written for. If you want to know whether the house works, that is a different visit by a differently licensed person with a different exclusion list, and the two reports answer questions that barely overlap.

The five things the scope of work actually requires

The form still in general use is Fannie Mae Form 1004 / Freddie Mac Form 70, March 2005 edition — six pages, read in full on 21 August 2026. Its SCOPE OF WORK paragraph sets the floor at five acts. The appraiser must (1) perform a complete visual inspection of the interior and exterior areas of the subject property, (2) inspect the neighborhood, (3) inspect each of the comparable sales from at least the street, (4) research, verify and analyze data from reliable public or private sources, and (5) report the analysis and conclusions in the report.

Read the certifications underneath and the boundary sharpens further:

• Certification 2 — the appraiser reports the condition of the improvements "in factual, specific terms" and identifies "the physical deficiencies that could affect the livability, soundness, or structural integrity of the property."
• Certification 7 — comparables selected are the ones "locationally, physically, and functionally the most similar to the subject property."
• Certification 9 — adjustments reflect "the market's reaction to the differences," not a contractor's price for the difference. A $30,000 kitchen does not produce a $30,000 line in the grid, and nothing in the form says it should.

Then the Statement of Assumptions and Limiting Conditions takes most of the rest back. Item 2: the sketch "is included only to assist the reader in visualizing the property." Item 3: the flood-zone note comes off FEMA maps and "because the appraiser is not a surveyor, he or she makes no guarantees." Item 5 is the one worth reading twice — unless the report says otherwise, the appraiser "has no knowledge of any hidden or unapparent physical deficiencies or adverse conditions," has assumed there are none, and "will not be responsible for any such conditions that do exist."

That is the whole silence in a nutshell. A defect that changes what a lender can lend against gets written down. A defect that only changes what you will spend in year three does not.

Your finished basement is not in the square footage

Fannie Mae adopted the standard in Announcement SEL-2021-11 of 15 December 2021, which gave lenders the option immediately and then made it binding "for all applicable appraisals with an effective date on or after Apr. 1, 2022." Since that date, gross living area on any appraisal requiring an interior and exterior inspection is measured and reported under ANSI Z765-2021. The rules that follow come from Fannie Mae's own guidance document, Standardizing Property Measuring Guidelines, dated 4 September 2025 and read 21 August 2026.

Two more points settle most arguments about this. First, there is no local-custom exception: where common practice in the market differs from ANSI, "the appraiser must measure and report the subject's square footage(s) following the ANSI standard." Second, there is no opt-out. Fannie Mae retired the old GXX001 exception code and now requires full compliance, with named declarations covering the cases where direct measurement is impossible. So if the appraisal reports 1,880 square feet against a listing that said 2,340, the gap is usually the basement plus a foyer, and it is not an error waiting to be corrected.

C4, Q3, and the rating that stops a loan

Two coded ratings sit in the grid for the subject and for every comparable. Condition runs C1 to C6, quality of construction runs Q1 to Q6, and both are absolute — Selling Guide B4-1.3-06 (06/04/2025, read 21 August 2026) requires the appraiser to rate the property on its own merits rather than against the neighborhood, and to keep the same rating attached to that same sale when the house later turns up as somebody else's comparable. The published definitions live in the UAD Condition and Quality Rating Definitions, version 1.0 dated 29 April 2025.

Most resale houses land at C3 or C4. C3 is well maintained with minimal wear. C4 is adequately maintained with deferred maintenance that is "generally minor or cosmetic in nature." C5 means obvious deferred maintenance and significant repairs needed, but the house still functions as a residence — and C5 is still eligible in "as is" condition.

C6 is the cliff. It means damage or deficiencies "severe enough to affect the safety, soundness, or structural integrity of the improvements," and the Selling Guide is blunt about the consequence: loans on C6 properties are not eligible for sale to Fannie Mae, the deficiency must be repaired to a resulting rating of at least C5, and the appraisal has to be completed "subject to" that repair rather than as is. There is no averaging out of it, either. If any portion of the dwelling rates C6, the whole dwelling rates C6.

The same machinery fires on smaller findings. Where the appraiser spots a physical deficiency affecting safety, soundness or structural integrity but is not qualified to evaluate it, the appraisal comes back "subject to" a satisfactory inspection by a qualified professional, and the lender decides whether that inspection is required. Evidence of wood-boring insects, dampness or abnormal settlement triggers the same fork: either documented proof the condition was corrected, or a professionally prepared report saying it poses no threat of structural damage to the improvements. That sentence is what pushes an appraisal-week finding onto a specialist's schedule and then onto a Form 1004D completion report, and it is one of the more ordinary ways a closing date slides by ten days.

The form under all of this changes on 2 November 2026

An appraisal ordered this week can come back on either of two entirely different documents. Fannie Mae and Freddie Mac are mid-migration from UAD 2.6, the dataset behind Form 1004 and its siblings, to UAD 3.6 and a single dynamic Uniform Residential Appraisal Report that replaces the whole family of legacy forms. The dates, from the two agencies' joint UAD redesign timeline, read 21 August 2026:

Those feedback messages key off the UCDP submission date, not the appraisal's effective date. A 2.6 appraisal ordered on 1 October 2026 is fine if it reaches the portal by 1 November and is not fine on 5 November. If your closing sits anywhere near that line, which version of the report your lender is ordering is a question worth asking rather than discovering.

What changes for a reader of the report is more than cosmetic. Under UAD 3.6 the single condition and quality ratings split into separate overall, interior and exterior ratings, so a house with new siding and an untouched 1974 kitchen stops averaging into one ambiguous letter. FHA is on a separate clock, and has been explicit that it is not the GSEs' one. In FHA INFO 2026-15, dated 25 June 2026 and filed in HUD's FHA INFO archive, FHA said development of its systems is "nearing completion," that beta testing with a limited number of mortgagees is under way, and that "FHA's adoption dates will be announced in the future." An FHA file therefore has no 2 November date of its own yet.

FHA and VA hang a second checklist on the same visit

On a conventional loan the appraiser answers one question: what is it worth. On FHA and VA loans the same visit also has to measure the property against a government minimum, and that is where appraisals start generating repair lists that look, to a buyer, exactly like inspection findings.

FHA's property acceptability criteria sit in Section II.D of HUD Handbook 4000.1. Minimum Property Requirements are the general standard that an FHA-insured home be safe, sound and secure; Minimum Property Standards are the construction-side rules that attach to new construction. The appraiser observes the property against those and conditions the report where it falls short. Open the handbook at that section and check the version date printed on it before relying on any particular item. HUD revises 4000.1 on a schedule of its own: the most recent set of updates went out as FHA INFO 2026-18 on 12 August 2026, and HUD posts a redline against the previous version on the Handbook 4000.1 information page whenever it does this.

VA moved more visibly this year. In a notice published 25 June 2026, VA announced MPR changes now in force through a revised Chapter 12 of the VA Lenders Handbook (Pamphlet 26-7): the full radon gas requirement at Topic 34 removed outright, the standards for properties built before 1978 and for those built in 1978 or later both revised at Topic 32, guidance on non-vented heaters updated at Topic 23, and detached-improvement and Specially Adapted Housing jurisdiction guidance streamlined at Topic 1. VA also reported that as of 31 May 2026 the average VA appraisal was taking approximately seven business days. If you are buying with a VA loan off a checklist of MPRs written in 2024, several lines on it stopped being requirements two months ago.

When the number lands under the contract price

You will see the report before closing whether or not anyone volunteers it. Under 12 CFR §1002.14(a)(1) — Regulation B, read on 21 August 2026 against eCFR text current to the 19 August 2026 issue — a creditor must give the applicant a copy of every appraisal and written valuation developed for a first-lien dwelling loan "promptly upon completion, or three business days prior to consummation of the transaction, whichever is earlier." You can waive the timing, but the waiver itself has to be obtained at least three business days before consummation, and the creditor cannot charge you for the copy.

The appeal route is a borrower-initiated reconsideration of value, and its contents are specified rather than freeform. Selling Guide B4-1.3-12, Appraisal Quality Matters (09/03/2025) requires the request to carry the borrower name, property address, effective date of the appraisal, appraiser name and date of the request; an identification and description of the unsupported, inaccurate or deficient parts of the report; additional comparable properties not to exceed five, each with its data source; and an explanation of why that data supports the change. The lender has to complete its own review first, route the request to a designated underwriter or appraisal subject matter expert, and communicate with the appraiser in a standardized form that preserves Appraiser Independence Requirements.

Two ways these fail are worth naming, because both are avoidable. Sending your comparables straight to the appraiser converts a valuation argument into an independence problem, and the request goes nowhere. And a request built on the size of the gap goes nowhere either — the same Selling Guide topic states that any request for a change in the opinion of market value "must be based on material and substantive issues and must not be made solely on the basis that the opinion of market value as indicated in the appraisal report does not support the proposed loan amount." What travels is a factual correction. A measured square footage that ignores an addition permitted in 2019. A comparable half a mile outside the school attendance boundary. A closed sale two streets over that never made the report.

Move quickly, because the clock is not the appraisal's. Your appraisal contingency deadline is a contract date that keeps running while the lender routes paperwork, and it sits inside a sequence of deadlines that does not pause for a review.

One thing holds across every row below. Even where the appraiser reviews your material and does not move the value, Fannie Mae's ROV FAQ requires the appraiser to update the report to correct any errors and to comment on the change — including the errors the appraiser has decided make no difference to the value. A corrected square footage on the report you already paid for outlives this closing — it is the document the next appraiser, and the next buyer's lender, will find.
