For most refinances, yes — the appraiser comes inside. A standard refinance appraisal includes an interior walk-through so the appraiser can confirm your home’s condition and market value, which the lender uses to set your loan-to-value ratio and interest rate. But whether appraisers come inside for a refinance depends on the loan program, your equity, and what the lender’s automated underwriting says: exterior-only appraisals, desktop valuations, hybrid appraisals, streamline refinance programs, and full appraisal waivers can all skip the interior visit, and some skip the appraisal altogether.
What the Interior Visit Actually Involves
A full interior appraisal is the default for most conventional refinances. The appraiser develops an independent opinion of your home’s market value under the Uniform Standards of Professional Appraisal Practice.1The Appraisal Foundation. USPAP
The on-site visit usually runs from 30 minutes to a few hours depending on the size of the home. The appraiser walks through every accessible area, evaluates overall condition and finish quality, and measures the footprint to verify livable square footage against local tax records. They photograph the kitchen, bathrooms, water heater, and electrical panel, and note any visible defects. Health and safety concerns get flagged too: missing handrails, chipping or peeling paint (especially in homes built before 1978, where lead paint is a concern), faulty smoke detectors, exposed wiring, and roof damage.
You can be home during the visit, and for a refinance you will likely need to be there to give the appraiser access. Let them work independently rather than following room to room. If you have information about recent improvements or comparable sales, hand it over in writing at the start rather than talking through it during the walk-through.
When Nobody Comes Inside
Several valuation methods let a refinance close without an appraiser stepping through your front door. Which one applies is decided by the lender’s automated underwriting system, not by you.
Exterior-Only Appraisals
An exterior-only appraisal, sometimes called a drive-by, requires the appraiser to view the property from at least the street without entering.2Fannie Mae. Exterior-Only Inspection Residential Appraisal Report The appraiser observes the neighborhood and the home’s exterior, then uses public records, tax data, and comparable sales to develop a value opinion. The interior is assumed to be consistent with the exterior and with similar homes nearby. It works well for properties with strong data histories but can undervalue homes with significant interior renovations.
Desktop Appraisals
A desktop appraisal skips the physical visit entirely. The appraiser works from MLS listings, tax assessments, prior appraisals, and digital imagery, including virtual inspection tools such as photos, videos, or machine-generated floor plans.3Fannie Mae. Desktop Appraisals Because the appraiser never sees the property in person, this option is typically offered only when the lender’s automated system determines the property has enough data and the transaction carries lower risk.
Appraisal Waivers
An appraisal waiver means no human appraiser, and no data collector, is involved at all. Fannie Mae’s program, called Value Acceptance, uses historical appraisal data and automated models to confirm a property’s value when the loan is run through Desktop Underwriter.4Fannie Mae. Value Acceptance Freddie Mac offers a similar program called Automated Collateral Evaluation through its Loan Product Advisor system.5Freddie Mac. Automated Collateral Evaluation (ACE)
Value Acceptance is limited to one-unit properties and condos. Two- to four-unit properties, co-ops, manufactured homes, and leasehold properties do not qualify.4Fannie Mae. Value Acceptance The system decides eligibility based on loan-to-value ratio, property data history, and the transaction’s overall risk. You cannot request a waiver directly; it is offered or not when the lender submits the loan. When a waiver comes through, it saves several hundred dollars in appraisal fees and can shorten closing by a week or more.
Hybrid Appraisals: Someone Comes Inside, But Not the Appraiser
A hybrid appraisal splits the work. A trained third-party property data collector physically visits your home to photograph it, measure the floor plan, and document its condition. That data goes to a licensed appraiser, who develops the value opinion remotely without visiting. Someone still enters your home under this method, but it is a data collector, not the appraiser. Hybrid appraisals are eligible for one-unit detached homes, attached homes, and condos.6Fannie Mae. Hybrid Appraisals
Streamline Refinances That Skip the Appraisal Entirely
If you already have a government-backed loan, a streamline refinance program may let you refinance without any appraisal at all. These programs exist to lower your rate or change your loan terms with minimal paperwork.
- FHA Streamline Refinance. You can refinance an existing FHA loan without a new appraisal. The program is available for both owner-occupied and investment properties, though investment properties may only be refinanced without an appraisal.7U.S. Department of Housing and Urban Development. Streamline Refinance Your Mortgage
- VA Interest Rate Reduction Refinance Loan (IRRRL). Veterans refinancing from one VA loan to another generally do not need a new appraisal for a fixed-to-fixed rate IRRRL. A fixed-to-adjustable-rate IRRRL does require a property valuation, though the lender can use either a full interior or exterior-only appraisal report.8Veterans Benefits Administration. VA Circular 26-19-22
- USDA Streamline Refinance. An existing USDA guaranteed loan does not require a new appraisal for a streamline refinance. Borrowers with a USDA direct loan who received payment subsidy are the exception; they need an appraisal to calculate any subsidy recapture owed.9U.S. Department of Agriculture. HB-1-3555 Chapter 6 – Loan Purposes
These programs bypass the appraisal because the government agency already insures the existing loan and has a prior valuation on file. Other program requirements still apply, including payment history and net tangible benefit tests, but the appraisal savings and faster timeline make streamline options worth exploring if you qualify.
FHA and VA Interior Appraisals Are Stricter
If your refinance does require an interior appraisal and you are going through FHA or VA, the appraiser applies a more demanding set of safety and habitability standards on top of the valuation work. These are known as minimum property requirements, and they can flag issues a conventional appraisal would overlook.
Common items that trigger repair requirements under FHA include:
- Peeling or chipping paint on any home built before 1978, which raises a lead-paint safety concern that must be resolved before closing.
- Roof condition problems, including active leaks or inadequate drainage.
- Nonworking plumbing, electrical, or HVAC systems, including exposed wiring or broken components.
- Missing handrails on staircases, broken steps, and nonfunctional smoke detectors.
- Inadequate ventilation, an unclean water supply, or a nonfunctioning sewage system.
VA appraisals work similarly. The VA appraisal generates a Notice of Value listing any items needing repair before the loan can close. For VA cash-out refinances, the property must meet all VA minimum property requirements, and the appraiser is ordered through VA’s own appraisal system.10Veterans Benefits Administration. VA Home Loan Guaranty Buyer’s Guide Any required repairs must be completed before the loan can fund.
How to Prepare If the Appraiser Is Coming Inside
A little preparation helps the appraisal reflect your home’s true value. Put together a list of capital improvements you have made: a new roof, an updated HVAC system, a remodeled kitchen, an added bathroom. Include the approximate cost and date of each project. The appraiser will not add the dollar amount you spent to the value, but documented upgrades help them make more accurate comparisons to similar homes that recently sold.
If you have added square footage, finished a basement, or built an accessory dwelling unit, gather the building permits. When an appraiser finds an addition that lacks a required permit, they must note its quality and comment on whether it affects market value.11Fannie Mae. Improvements Section of the Appraisal Report Proving permit compliance avoids that issue.
Make every room accessible, including the attic, basement, and any crawlspace. Clear paths to the water heater, furnace, and electrical panel so the appraiser can photograph them without obstacles. Electricity, water, and gas should all be on so the appraiser can confirm major systems work. A land survey or deed showing property boundaries is worth having handy in case questions come up about lot size or encroachments.
Getting Your Copy of the Appraisal
Federal law requires your lender to give you a free copy of the appraisal report. Under Regulation B, the lender must provide it either promptly after the report is completed or at least three business days before your loan closes, whichever comes first. You can waive the timing requirement and agree to receive the copy at closing, but the lender cannot charge you for it regardless of when it arrives.12Consumer Financial Protection Bureau. 1002.14 Rules on Providing Appraisals and Other Valuations
Read it carefully when you get it. Check the property description for errors in square footage, bedroom and bathroom count, and lot size. Confirm that the comparable sales used are genuinely similar to your home in size, age, and location. Factual mistakes or questionable comparables are the basis for challenging the value.
Challenging a Low Appraisal
If the value comes in lower than expected, you have the right to request a reconsideration of value. This is a formal process, not a phone call to complain, and both Fannie Mae and FHA have specific rules.
You get one reconsideration request per appraisal.13Fannie Mae. Reconsideration of Value (ROV) Submit concrete evidence to your lender. The strongest submissions include comparable sales the appraiser may have missed, ideally homes more similar to yours than the ones used in the report. For FHA loans, you can provide up to five alternative comparables for the appraiser to consider.14HUD Archives. Appraisal Review and Reconsideration of Value Updates Factual errors count too: an incorrect room count, wrong square footage, a missed renovation.
Your lender reviews the request before forwarding it to the appraiser and should work with you to complete any missing information.13Fannie Mae. Reconsideration of Value (ROV) The appraiser then decides whether to adjust the value, leave it unchanged, or in rare cases revise it downward. For FHA loans, the reconsideration must be resolved before the loan can close.14HUD Archives. Appraisal Review and Reconsideration of Value Updates
If the reconsideration does not raise the value and the low number kills your refinance, your options include paying down the balance to improve your loan-to-value ratio, waiting for the market to appreciate, or trying a different lender who may order a new appraisal.
