For a standard mortgage on a home purchase, yes — appraisers usually need to enter the home, walk every room, and document the interior in person. But that is not the only path a lender can take. Depending on the loan type, your equity, and the automated risk assessment behind the file, the appraisal may be done from the curb, from the appraiser’s desk, by a non-appraiser data collector, or skipped entirely. The rules are strictest on FHA, VA, and USDA loans, where an interior inspection is effectively non-negotiable.
The Standard Purchase Appraisal Requires Interior Access
The default valuation for a conventional home purchase is the Uniform Residential Appraisal Report on Fannie Mae Form 1004. That form explicitly requires “an interior and exterior on-site physical inspection of the property by the appraiser.”1Fannie Mae. Appraisal Report Forms and Exhibits The appraiser walks through the house, measures the living area, photographs its condition, and compares what they see to public records and recent local sales.
The visit typically lasts anywhere from 30 minutes to a few hours. Fannie Mae requires interior photographs of the kitchen, all bathrooms, main living areas, every bedroom, all below-grade spaces (finished and unfinished), any visible deterioration, and any recent upgrades or renovations.1Fannie Mae. Appraisal Report Forms and Exhibits The appraiser also records the room count, measures gross living area against tax records, notes flooring and finishes, and documents both upgrades and deferred maintenance because both push value.
If the property has an accessory dwelling unit — a basement apartment, in-law suite, or detached guest house — the appraiser inspects that too.2Fannie Mae. Accessory Dwelling Units (ADUs)
When No Appraisal Happens at All
Before worrying about who enters, check whether your loan even needs an appraisal. Fannie Mae’s value acceptance program, once known as an appraisal waiver, lets certain loans close without one. When the lender runs your file through Desktop Underwriter, the system compares the submitted value against a database of prior appraisals and analytics. If the data is strong enough, Fannie Mae accepts the value and waives the appraisal entirely.3Fannie Mae. Value Acceptance Freddie Mac runs a parallel program called Automated Collateral Evaluation.
Value acceptance is most common on refinances with substantial equity and on purchases in neighborhoods rich with recent sales. There is no guarantee your loan will qualify; the automated system decides case by case. When it does, nobody enters or even visits your home.
Exterior-Only Appraisals
When a lender wants a professional opinion but not full interior access, they may order an exterior-only appraisal on Fannie Mae Form 2055. The appraiser performs “a visual inspection of the exterior areas of the subject property from at least the street” and never crosses your threshold, filling in the rest from MLS data, tax records, prior appraisal files, and information provided by the owner.4Fannie Mae. Exterior-Only Inspection Residential Appraisal Report
The approach assumes the interior condition is consistent with the exterior and the neighborhood, so lenders reserve it for lower-risk situations: a refinance with strong equity, a home equity line of credit, or a portfolio review. You will not see this option on a high loan-to-value purchase.
Desktop and Hybrid Appraisals
Desktop and hybrid appraisals sit between a waiver and a traditional inspection. They differ on one key point: whether anyone enters your home.
Desktop Appraisals
A desktop appraisal is completed entirely from the appraiser’s office. The appraiser analyzes comparable sales, tax records, and property data supplied by the homeowner, borrower, or a third party, but never visits the property. The lender remains responsible for the accuracy of the property data in the report, which is part of why desktop appraisals are typically offered only when the automated underwriting system flags the transaction as low risk.5Fannie Mae. B4-1.2-02, Desktop Appraisals Nobody enters your home.
Hybrid Appraisals
A hybrid appraisal does involve someone entering the home, but not the appraiser. A trained third-party data collector visits, measures, photographs the interior and exterior, and transmits the data to the appraiser, who completes the valuation remotely.6Fannie Mae. Hybrid Appraisals The collector can be a real estate agent, home inspector, insurance inspector, appraiser trainee, or another vetted individual; a licensed appraiser is not required.7Fannie Mae. Property Data Collection: What QC Professionals Need to Know Lenders must vet the collector’s credentials annually.
From your side of the door, a hybrid still means someone walks through every room. The person measuring your bedroom just is not the one who determines the value.
FHA, VA, and USDA Loans Require an Interior Inspection
Government-backed loans come with tighter rules because a federal agency is insuring the lender. Skipping the interior is not an option.
FHA
FHA appraisals do more than estimate market value. The appraiser must verify that the property meets HUD’s minimum property standards for safety, security, and structural soundness: HVAC, electrical, and plumbing function, hot water at all fixtures, handrails on stairways with three or more steps, and no signs of structural damage or pest infestation.
In June 2025, HUD issued Mortgagee Letter 2025-18, which rescinded several requirements that went beyond industry standards. Among the changes, FHA dropped the mandatory photograph requirement for attics and crawl spaces.8U.S. Department of Housing and Urban Development. Mortgagee Letter 2025-18, Rescission of Outdated and Costly FHA Appraisal Protocols Basement photographs are still required, and the appraiser still needs to physically enter and inspect the interior. Individual lenders may impose their own overlays.
One FHA-specific issue to know about: in any home built before 1978, chipping or peeling paint must be addressed before the loan can close because of the lead hazard risk. HUD requires that defective paint be treated by covering or removal; washing and repainting over damaged paint does not qualify.9HUD Portal. Interpretive Guidance on HUD’s Lead Safe Housing Rule
VA
The VA requires its fee appraisers to personally visit and observe both the interior and exterior. The only exception is a liquidation case where interior access has been denied or is not possible, and even then the appraiser must document three reasonable attempts to gain entry before falling back to an exterior-only report.10Department of Veterans Affairs. VA Fee Panel Appraiser’s Handbook On a standard VA purchase, refusing entry kills the appraisal and the loan with it.
USDA
USDA Rural Development loans also require a full interior and exterior appraisal. Utilities matter to the outcome: when the home’s utilities are on, USDA limits the contingency reserve on any required repair escrow to 10%; when utilities are off and systems cannot be verified, the reserve jumps to 15%.11USDA Rural Development. HB-1-3555, Chapter 12 – Property and Appraisal Requirements Selling a vacant property with disconnected utilities means expecting the appraiser to flag it and the lender to hold back additional funds.
What Happens if You Refuse Entry
If a lender orders a traditional appraisal and you do not let the appraiser inside, the appraisal cannot be completed and the loan stalls. For FHA and VA loans, that is effectively a deal-breaker. For a conventional loan, the lender could in theory switch to a desktop or exterior-only product if the automated underwriting system supports it, but that is the lender’s call, not yours, and most will not bother on a standard purchase.
You may also owe money even without an appraisal on file. If an appraiser travels to the property and cannot get in, appraisal management companies typically charge a trip fee. The VA caps this cancelled-assignment fee at $175.12Department of Veterans Affairs. VA Appraisal Fee Schedules and Timeliness Requirements Private appraisal management companies set their own rates, generally $75 to $150. That cost comes out of the transaction whether the appraisal is completed or not.
Preparing for the Interior Visit
The appraiser is not judging your housekeeping, but a little preparation avoids a return trip and a re-inspection fee.
- Clear access to the basement, attic hatch, electrical panel, water heater, and HVAC unit. Blocked access is one of the most common reasons appraisers have to come back.
- Turn utilities on. The appraiser needs to verify that major systems work, and USDA in particular penalizes disconnected utilities with a larger repair reserve.
- Have a list of significant upgrades with approximate dates: new roof, kitchen renovation, replaced HVAC, updated electrical panel. The appraiser may not know your kitchen was gutted last year unless you say so.
- Fix the obvious safety issues in advance: missing handrails, broken smoke detectors, exposed wiring, and peeling paint in pre-1978 homes. These are the items most likely to trigger a “subject to repair” condition.
- Unlock everything, including sheds, detached garages, ADUs, and gated areas.
You do not need to be home. A real estate agent or another trusted person can provide access. What matters is that every part of the property is reachable and every system is running.
