You are refinancing, and somewhere in the first conversation someone mentions you might not need an appraisal. That sounds like good news. It usually is. It also raises a fair question: who decides, and why did the neighbor with the nearly identical house get one when you did not?
The short answer is that nobody at your lender decides. An automated underwriting system does, and it decides based on data your property either has or does not have. Below is how that call actually gets made on a mortgage refinance, what moves the odds, and what it means for your file if the answer comes back no.
What an appraisal waiver actually is
When you apply for a mortgage refinance, your file runs through an automated underwriting system. That system compares the value you and your lender submitted against its own model, which is built on historical appraisals, public records, and prior transactions tied to the property. If the model is confident enough in that number, it returns an offer to accept the submitted value without ordering a new appraisal.
That offer is what people have long called an appraisal waiver.
Two details matter more than most borrowers are told. First, the value is not waived. Only the in-person appraisal is. A value is still assigned, and your loan is still sized against it. Second, the offer attaches to the loan file, not to you. Change the loan amount, the occupancy type, or the value submitted, and the system starts over. Waivers appear and vanish as files change, which is why one can be mentioned early and quietly disappear later.
The name changed, and the change tells you something
Fannie Mae retired the term "appraisal waiver" in September 2025 and now calls the same thing value acceptance. Freddie Mac's equivalent has always gone by Automated Collateral Evaluation, or ACE.
That is more than branding. "Waiver" suggests a rule got bent in your favor. "Value acceptance" describes what really happened: the system had enough evidence to accept a number without sending anyone to walk the property. Nothing was skipped as a courtesy. A different valuation method was used because the data supported it.
Holding that framing changes the question worth asking. Most borrowers ask whether they are strong enough to qualify. The more useful question is whether the property itself carries enough recent, clean data for a model to stand behind a number without a person walking through the front door.
Who gets one: the three gates
Gate one: how much you are borrowing against the home
Loan-to-value does most of the work. The smaller your loan is relative to the home's value, the more room the model has to be wrong without anyone getting hurt, and the more willing it is to skip the appraisal.
Under current agency guidelines, a rate-and-term mortgage refinance with no cash out can qualify for value acceptance up to 90 percent loan-to-value on a primary residence or second home. On an investment property that ceiling drops to 75 percent. Cash-out refinances are held to a tighter standard, generally 70 percent on a primary residence and 60 percent on a second home or investment property. Freddie Mac's ACE program runs on closely matching thresholds, with no-cash-out refinances allowed up to 90 percent and cash-out capped at 70 percent for a primary residence.
Those are ceilings, not targets. Sitting at 89 percent on a rate-and-term refinance is technically inside the box and still far less likely to produce an offer than sitting at 60 percent. Borrowers who have held a home for a decade and paid down principal tend to see waivers routinely. Borrowers pulling cash near the top of the allowable range rarely do.
Gate two: whether the property already has a recent, usable value
Models need something to work from. A home that sold three years ago, was appraised for a refinance two years ago, and sits in a neighborhood with steady turnover has a thick file. A home that has not changed hands in thirty years, on five acres, with no close comparable sales, has almost nothing.
This is why the outcome can feel arbitrary from the outside. Two owners with the same credit profile and the same equity get different answers because their properties have different histories.
There is also a rule that surprises people. Automated underwriting will not offer value acceptance when an appraisal has already been uploaded to the Uniform Collateral Data Portal within the prior 120 days, by any lender. If you started a mortgage refinance a few months ago, paid for an appraisal, and walked away, that appraisal is on record and blocks the waiver path for everyone until the clock runs out.
Gate three: whether the property is ordinary enough to model
Manufactured, modular, and mobile homes are excluded from value acceptance and its related alternatives. Unique properties, homes with acreage, mixed-use parcels, and anything a model cannot match against comparable sales tend to land the same way.
Condition matters too. If your lender learns that a recent disaster affected the area, an appraisal is required regardless of what the automated system said, and the lender is responsible for determining whether the property's condition materially changed before the loan is delivered. Homeowners in Florida, the Carolinas, and other storm-exposed markets run into this more often than the guidelines make obvious.
What quietly kills a waiver on a strong file
Smart people run into these every day, because none of them are advertised.
An appraisal from an application you abandoned months ago is the most common one. The 120-day rule applies across lenders, so a fee you already paid somewhere else can close the door here.
A value estimate that reaches is the second. If the number submitted sits meaningfully above what the model supports, the system does not stretch to meet it. It orders an appraisal. Inflating the estimate to try to force a waiver is the reliable way to lose one.
A renovation the public records have not caught up with can also work against you. A finished basement or a new addition may genuinely make the home worth more than the data shows, and that gap reduces the model's confidence rather than raising it.
Changes made partway through the process reset everything. Moving from rate-and-term to cash out, raising the loan amount, or converting a former primary residence to a rental all send the file back through evaluation under different thresholds.
None of this is a judgment on you. The valuation system exists to limit loss on the loan, and it withholds shortcuts exactly where its own data thins out.
If you have a VA loan, the rules are different
Veterans have their own set of rules, and they are more generous in one direction and stricter in the other.
On an Interest Rate Reduction Refinance Loan, VA does not require an appraisal or a credit underwriting package at all. That is written into the program. Individual lenders may still ask for one, so it is worth confirming early whether the file you are being quoted includes an appraisal fee that the benefit does not require.
On a VA cash-out refinance, an appraisal is required, and you also qualify on income and credit. There is no waiver path. If someone tells you otherwise on a cash-out file, ask them to show you where.
The benefit you earned includes a valuation rule most borrowers do not get. It is worth knowing which side of it your loan falls on before you agree to pay for anything.
A waiver saves time. It does not decide whether the loan is good.
This is where borrowers get steered wrong. A waiver is a convenience, and it is a real one. Freddie Mac reported that as of the second quarter of 2025, ACE loans closed on average 12 days faster than refinances that required an appraisal. Twelve days off a timeline is worth something, especially when you are consolidating balances and every month of high-interest payments counts.
But the appraisal fee is a few hundred dollars on one line of your Loan Estimate. It is not the number that determines whether a mortgage refinance was worth doing. That number is the total: the fees rolled into your balance, the term you reset to, the blended cost of the debts you are folding in, and what you will have paid by the time the loan is gone.
Choosing a loan because it came with a waiver is choosing on the smallest variable available. A file that skips the appraisal and adds a longer term or heavier costs is the more expensive outcome, and it will feel cheaper for about thirty days.
You are entitled to see the valuation either way
Whether a full appraisal is done or a model assigns the value, you have a right to what was produced. Under the CFPB's ECOA Valuations Rule, a lender must notify you in writing within three business days of your application that you will receive copies of appraisals and other written valuations, and must send those copies to you free of charge and promptly after they are completed. That applies whether your loan closes, is denied, or is withdrawn.
Ask for it. Read it. If your home is valued lower than you expected, the report tells you what the valuation was based on, and that is the starting point for any conversation about accuracy.
What to do if you get an appraisal instead
Getting an appraisal ordered is not a setback. It often works in your favor, particularly if you have improved the home or your neighborhood has moved faster than the records show. A model cannot see a renovated kitchen. An appraiser can.
A few things help:
- Give your lender an honest value estimate at the start rather than an aspirational one.
- Have documentation of permitted work, with dates and costs, ready before the appraiser arrives.
- List recent nearby sales you are aware of, especially ones that closed in the last few months.
- Handle visible deferred maintenance where you can. Condition notes can affect both the value and the loan conditions attached to it.
Where GoodLoan fits
We will tell you early whether your file has a realistic shot at value acceptance, and we will tell you plainly when it does not, rather than letting you find out at the appraisal invoice. We also say no a fair amount, because a refinance that does not improve your total position is not one worth closing.
If you want to know where your property sits before committing to anything, a GoodLoan loan officer can walk through your equity position, the likely valuation path, and the full cost of the loan in one conversation. You do not need to start an application to have it. GoodLoan is VA-approved and licensed under NMLS #1972491, an Equal Housing Lender.
Frequently asked questions
Can I request an appraisal waiver?
No. There is no application for one. The offer is generated by the automated underwriting system when your file and your property meet its criteria. Your lender can tell you whether one was issued, and can tell you what is standing in the way when it was not.
Does a higher credit score improve my chances?
Indirectly at most. Credit affects your loan approval and your pricing. The valuation decision is driven primarily by loan-to-value, property type, and the data history attached to the address. A strong borrower with an unusual property will often get an appraisal, and that is normal.
If I got a waiver on my purchase, will I get one on my mortgage refinance?
Not automatically. Each transaction is evaluated on its own, and refinance thresholds differ from purchase thresholds. Cash-out refinances in particular are held to tighter limits than the loan you may have used to buy the home.
Can I use a waiver on a cash-out refinance?
Sometimes on a conventional loan, if your loan-to-value is low enough and the property qualifies. On a VA cash-out refinance, no. VA requires an appraisal on that product.
What if the assigned value looks too low?
Request the written valuation, which you are entitled to receive at no cost. Review the comparable sales and the property details used. If something is factually wrong, such as square footage, bedroom count, or unpermitted versus permitted work, bring the documentation to your loan officer and ask what the reconsideration process looks like on your file.
Does skipping the appraisal mean my loan closes faster?
Usually yes, on the order of a week and a half based on recent agency data. It does not remove the other timelines in a mortgage refinance, including title work, payoff statements from your existing servicer, and the required disclosure waiting periods.
