The Quick Read: The appraisal sets the bottom of the loan-to-value ratio, so a low number can leave your new loan above the 80% line where mortgage insurance stops. Your payoff and any rolled-in costs stay the same while the value shrinks. That pushes the ratio up. You can still pay the gap down, challenge the value with evidence, keep the insurance, or walk away.
Key Takeaways
- One ratio decides this: the new loan amount divided by the appraised value.
- On a conventional loan, mortgage insurance is required above 80% of value.
- A small miss can often be fixed with a modest paydown. A large miss usually can’t.
- You can challenge a value, but only with facts and comparable sales.
- FHA and VA refinances follow different rules, and a low value matters less for them.
- Sometimes the right move is to stop. The break-even math tells you when.
How Does the Appraisal Decide Whether the Insurance Drops?
The appraisal is the denominator in the only ratio that matters here. Divide the new loan amount by the appraised value. If the result is 80% or lower, conventional mortgage insurance is no longer required on the new loan. If it lands above 80%, the insurance stays.
Refinance savings and break-even estimate
The starting figures are an example value with a balance in proportion and a placeholder for costs. Replace them with yours, and enter the current rate from your statement.
Editable benchmark: 7.32% as of October 22, 2026 · Freddie Mac 30-year average via FRED®. A conventional market reference, not a refinance quote.
Illustrative starting assumptions: a $350,000 home value, a $245,000 current balance, a current rate you enter and a remaining term seeded at twenty-five years, closing costs seeded at $5,000 as an editable placeholder (not a fee quote) and rolled into the new loan, a thirty-year term at the current Freddie Mac benchmark, and property taxes and insurance estimated at typical national rates. Every field is editable.
Illustrative estimate only — not a Loan Estimate, approval, quote, or commitment to lend. The new rate field carries the weekly Freddie Mac thirty-year conventional benchmark, a market reference and not a refinance quote; a refinance is priced by the lender at lock, and the current rate, the remaining term and the closing costs are figures you enter. The current payment is estimated from the balance, the current rate and the remaining term; the break-even divides the closing costs by the monthly saving and ignores the interest effect of a longer term. On the VA IRRRL the funding fee is added to the loan unless the veteran is exempt. Taxes and insurance are editable estimates.

The new loan amount is more than your current balance. It includes the payoff, plus any closing costs you roll in, plus any financed fees. A homeowner who expects a clean 78% can land above 80% with a lower value, or with costs added on top.
Here is the formula in plain form:
LTV = (payoff + rolled-in costs + financed fees) ÷ appraised value
Loan-to-value, or LTV, is the share of the home's value you owe. Lendmire's refinance programs are built around that test. Across the wholesale lenders Lendmire places files with, a rate-and-term refinance on a one-unit primary residence can reach 95% LTV, and 97% where the existing loan is agency-owned and a first-time-buyer program allows it. Mortgage insurance applies above 80% in both cases. All of it is subject to lender guidelines and full file review.
That 95% figure is the ceiling, not the goal. If your goal is to drop the insurance, 80% is your number. A low appraisal pulls you away from it.
How Is the Refinance Underwritten, Step by Step?
The lender sets a target, orders a value, recalculates the ratio, and then decides what the file can support. Here is the sequence on a typical conventional refinance.
1. Set the target. You want a new loan at or below 80% of value. Add up the payoff, rolled-in costs, and financed fees.
2. Decide how value will be set. Sometimes the automated system accepts an estimated value and no appraisal is ordered. That is a per-file result. You can't count on it.
3. Order the appraisal. The appraiser works for the lender, and you usually pay for the report. The fee is generally owed even if the refinance doesn't go ahead.
4. Receive the report. You are entitled to a copy of the appraisal. Under the CFPB's appraisal rule, lenders must deliver it promptly after it is completed, and the exact timing varies by file and lender. You can waive the timing.
5. Recalculate the ratio. The underwriter divides the new loan amount by the appraised value, not by the value you hoped for.
6. Pick the outcome. The file closes as planned, closes with insurance, closes with a paydown, or stops.
The same value also feeds the credit side of the file. Most wholesale conventional programs start at a 620 decision score, and the automated finding governs most files. The value itself doesn't change your score. It changes how much room you have under the leverage cap.
What Does a Low Number Actually Do? Three Scenarios
Run the numbers on a homeowner whose new loan, with costs rolled in, equals 78% of the value they expected. These are modeled assumptions, not market data. They show how the ratio moves.
| Appraisal vs. your estimate | Resulting LTV | Insurance drops? | Best next move |
|---|---|---|---|
| 2% lower | About 79.6% | Yes, barely | Stop rolling in costs to keep a cushion |
| 5% lower | About 82.1% | No | Pay down about 2% of the expected value |
| 10% lower | About 86.7% | No | Pay down about 6%, or reconsider |
The close miss is the dangerous one, because it looks fine. A tiny change in rolled-in costs can tip it back over 80%. A medium miss is often fixable with cash. A large miss needs a different plan, because the paydown starts to look like a down payment on a loan you already have.
(The paydown figures are percentages of the value you expected. Your lender converts them to dollars on your actual file.)
First Moves After a Low Number
Start by reading the report, not by reacting to the headline figure. A methodical review often matters more than a fast decision.
1. Get the full report. You have a right to a copy of the appraisal, and the report lists the comparable sales behind the value.
2. Check the facts. Look for the wrong square footage, wrong bedroom or bath count, missed upgrades, or comps that don't resemble your home.
3. Recalculate your own ratio. Use the new value and the real loan amount, including every rolled-in cost.
4. Decide the lane. A close miss points to a paydown. A medium miss points to a challenge or a paydown. A large miss points to stopping or switching strategy.
5. Talk to the loan officer, not the appraiser. Appraisers work through the lender, so feedback goes through the lender.
One pattern shows up often across the wholesale files Lendmire places. Borrowers fixate on the appraisal fee they've already paid. The better question is whether the new loan still beats the one you have, once the paydown is counted.
Can You Challenge the Value?
Yes, but a challenge needs evidence, not frustration. The formal route is a reconsideration of value, which means asking the lender to have the value looked at again. Federal interagency guidance on reconsiderations of value says the requester should submit comparable sales with the address, sales price, sale date, and gross living area, plus listing details where they apply.
What makes a request credible:
- Factual errors in the report, such as a wrong room count or lot detail.
- Closer, more recent comparable sales that the appraiser didn't use.
- Specifics about condition or updates that the report missed.
What doesn't help: a high online estimate, a neighbor's asking price, or a feeling that the number is unfair. A challenge can also come back with the same value. Some lenders limit how many requests they accept on one appraisal, so make the first one count.
Ordering a second appraisal sounds tempting. Know that it can cost you another fee, and it may land close to the first. Usually it's a last resort.
Is Paying Down the Loan Worth It?
A paydown, sometimes called a cash-in refinance, means bringing cash to closing so the new loan lands at or under 80%. It works when the cash you need is modest compared with what the insurance costs you over time.
The break-even math has three steps:
1. Find the paydown. Take 80% of the appraised value and subtract it from your planned loan amount. The difference is the cash needed.
2. Find the monthly insurance you'd stop paying. Published typical annual mortgage insurance premiums run from 0.58% to 1.86% of the balance. That is a range, not a quote, and your own premium depends on your file.
3. Divide. Cash needed divided by the monthly insurance saved gives the months to recover the paydown.
If that recovery period is shorter than the time you expect to stay in the home, the paydown can make sense. If it's longer, you may do better keeping the insurance or leaving the loan alone. Ending PMI does lower monthly costs, as the Consumer Financial Protection Bureau (CFPB) notes, but the savings only matter once you net out the cash you put in.
Don't forget the other costs. Closing costs, the appraisal fee, and the reset of your loan term all count. A refinance that drops insurance isn't automatically a refinance that saves money.
Your Exits Depend on the Insurance Type
Not every kind of mortgage insurance ends the same way. Before you chase a refinance, know which kind you carry.
| Insurance type | How it usually ends | Is refinancing the only exit? |
|---|---|---|
| Conventional PMI (borrower-paid) | Cancellation at 80% or automatic at 78%, or refinance | No |
| Lender-paid PMI | Built into the loan terms, so generally a refinance | Often yes |
| FHA mortgage insurance | Depends on the original down payment and loan date | Often yes |
| VA loan | No monthly insurance; a one-time funding fee | Not applicable |
The federal PMI cancellation law covers conventional loans. It doesn't cover FHA insurance, which follows its own rules. Fannie Mae's consumer site notes that FHA mortgage insurance may involve refinancing. Lendmire's piece How to Refinance Out of FHA Mortgage Insurance on a Low Appraisal covers that exit in more depth.
If you hold conventional PMI, a low appraisal doesn't close every door. You can ask your servicer to cancel instead. The servicer must terminate it automatically at the scheduled 78% point. A servicer must grant a request if you meet four conditions:
- The request is in writing.
- Your payment history is good.
- You have no junior liens.
- You can show the value hasn't fallen below the original value, for example with an appraisal.
Some lenders and servicers allow removal under their own standards too. This route tests a different value than the refinance does, so a low refinance appraisal doesn't automatically end it.
Where the General Rule Breaks
The "low value blocks the drop" rule holds for the common case. Here are the named exceptions.
FHA Streamline. An existing FHA loan can often be refinanced with no appraisal, limited credit review, and a net tangible benefit, meaning the borrower must come out measurably better. A low value barely matters. The catch is that the new loan stays in FHA, so the mortgage insurance stays. It isn't an exit. HUD's older handbook guidance on streamline refinances describes the same principle: an appraisal is optional, and the annual premium continues.
FHA rate-and-term with an appraisal. This path goes to 97.75% LTV, so the appraisal does shape what you can borrow. It still keeps you in FHA. Every figure here varies by lender and program, and guidelines, property type, leverage, and credit profile all apply.
VA IRRRL. An existing VA loan can be refinanced with no VA appraisal, a net tangible benefit, and seasoning of the later of 210 days and six payments. The funding fee is 0.5% unless you're exempt. VA loans carry no monthly mortgage insurance, so there is nothing to drop, and a low value matters little.
Value acceptance. Sometimes the automated underwriting system accepts an estimated value and no appraisal is ordered. That removes the low-appraisal risk, but you can't request it. The system decides.
Occupancy and units. The agencies set lower maximum leverage on two- to four-unit homes, second homes, and investment properties, and the limits differ by loan type. Freddie Mac's Guide section 4203.1 lists them. Occupancy decides the cap.
Limited cash-out rules. A rate-and-term refinance is technically a limited cash-out loan. It can pay off the first mortgage, closing costs, and a purchase-money second lien, with only incidental cash back. Title rules apply too: at least one borrower must generally be on title at application, with exceptions for inheritance, divorce, a revocable-trust beneficiary, and a few others.
Cash-out refinance. A true cash-out carries a lower cap: 80% LTV on a one-unit primary residence and 75% on two- to four-unit homes. A low appraisal squeezes both the insurance goal and the cash you can take. Cash-out also needs the first mortgage to be at least 12 months old. Final terms depend on lender guidelines, property type, leverage, and the borrower's complete credit picture.
Jumbo loans. Above the conforming limit, jumbo lanes take over, with a 660 decision score and leverage up to 90% on the programs Lendmire places. The appraisal still sets the ratio. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
Does the Low Number Follow You?
It can. A refinance appraisal is a data point about your home's value, and a low number may make a later PMI cancellation request harder. The servicer-side route asks you to show the value hasn't dropped below the original. A fresh appraisal that comes in under it is evidence against you.
A failed refinance also leaves your existing loan alone. Your current insurance, the 80% request point, and the 78% automatic termination all stay on their own schedule. Nothing resets unless a new loan closes.
Here is the reset to watch: when a refinance does close, it creates a new loan with a new original value. The 80% and 78% marks then count from that new value and new schedule. Mortgage insurance on the new loan runs on a new clock.
When to Stop
Stopping is a legitimate result. Treat the refinance as a trade. If the paydown, closing costs, and a reset loan term outweigh the insurance savings over the time you'll stay, the answer is no.
Walk away or wait when:
- The paydown needed is large compared with your cash reserves.
- The insurance on the new loan, if kept, would cost about the same as what you pay now.
- Your recovery period runs longer than the time you plan to keep the home.
- The challenge has no real evidence behind it.
- Your current loan already has a clear cancellation date coming.
Why Appraisals Come In Low
Most low numbers trace back to a short list: comparable sales that don't match your home, a market that shifted after those sales, condition issues, or an appraiser who doesn't know the neighborhood well. Check the report for each one before you decide it's simply "wrong." Sometimes the number is accurate and your expectation was off.
Key Terms Defined
Loan-to-value (LTV): The new loan amount divided by the home's appraised value, shown as a percentage.
Mortgage insurance (PMI): Coverage that protects the lender, paid by the borrower, when a conventional loan starts above 80% LTV. Terms depend on the lender's guidelines, the property type, the leverage, and a full review of the credit profile.
Reconsideration of value: A formal request that the lender have the appraised value looked at again, backed by comparable sales or factual corrections.
Cash-in refinance: A refinance where you bring cash to closing to reduce the new loan amount and hit a target LTV.
Net tangible benefit: A test on government streamline loans that requires the borrower to come out measurably better after the refinance.
Original value: The lower of the price paid or the appraised value when the loan was made. PMI cancellation by law counts from it.
What to Do Next
If you are weighing a refinance and want the break-even run on your own numbers, Lendmire can help you compare the programs on the same home. Do that before the appraisal is ordered, not after.
Frequently Asked Questions
Can a second appraisal change the outcome?
Sometimes, but not reliably. A second appraisal may use different comps and land higher, or it may match the first. It costs another fee, and the lender may or may not accept it. A reconsideration of value with specific evidence is usually the better first step.
Do I lose the appraisal fee if the refinance falls through?
Generally yes. The appraiser did the work, and the fee is usually owed whether or not the loan closes. That is a reason to run the break-even before the appraisal is ordered.
Do I have to refinance to remove PMI?
No. On a conventional loan you can request cancellation once your balance is scheduled to reach 80% of the original value, if you meet the servicer's conditions. The servicer must end it automatically at 78%. Refinancing makes sense when you want to remove it sooner and the math supports it.
Will an FHA Streamline get rid of my mortgage insurance?
No. A streamline stays inside FHA, so premiums continue. It can work regardless of value, which is its appeal, but it isn't a way out of the insurance. Dropping FHA insurance generally requires a move to a conventional loan with enough equity.
What if the appraisal is below what I owe?
Then the new loan can't be sized to fit, and a conventional rate-and-term refinance generally can't proceed without a large paydown. Some existing government loans have streamline paths that don't depend on value. A loan officer can tell you which option, if any, your loan allows, subject to lender guidelines.
