The Quick Read: A low appraisal lowers the maximum loan the program allows, because the cap is a percentage of appraised value. Usually the loan shrinks, the closing costs you planned to roll in may have to come out of pocket, and mortgage insurance can enter the picture if the loan-to-value ratio crosses 80%. You can request one reconsideration of value, resize the loan, or change program, subject to lender guidelines and full file review.
How the Appraisal and the Cap Set the Loan
The appraised value is the bottom of the loan-to-value fraction. Loan-to-value (LTV) is the new loan divided by appraised value. The program cap is the highest LTV that program allows.

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.

Take a one-unit principal residence on a rate-and-term refinance. Across the wholesale programs placed through Lendmire, the cap is 95% LTV, and 97% where the existing loan is agency-owned and the first-time-buyer program allows it. The new loan pays off the existing first mortgage, the closing costs and any purchase-money second lien. Only incidental cash comes back to you. Terms depend on the lender's guidelines, the property type, the leverage, and a full review of the credit profile.
Here's the catch. If you size the request right at the cap and the value comes in light, the same loan now sits above the cap. The program does not bend. The loan has to shrink, or something else has to change.
Run it in percentages. Say you request a loan at 95% of the value you expected. The appraisal lands 3% under that value. Your same loan is now roughly 98% of the new value. That is over the cap by about three points, and those three points have to be made up in cash or a smaller loan. A 5% miss makes the gap bigger. Every point of lost value moves the ceiling down by about the same share of the home's price.
For the basics on what is available, see Lendmire's refinance programs. The mechanics below apply once a conventional file has a new appraisal in it.
What Actually Happens, Step by Step
On most files, the sequence runs like this.
1. Application and disclosures. The lender gives you a written notice that you can receive a copy of any appraisal. On conventional loans, the lender also gives a reconsideration-of-value disclosure.
2. Value is established. The appraiser reports a value. The lender reviews the report itself before relying on it.
3. The cap test. The underwriter divides the requested loan by the appraised value and compares the result with the program ceiling.
4. If the value comes in low, one of four paths follows: a reconsideration request, a smaller loan, a different program or transaction type, or stopping the deal.
5. The file is re-run at whichever path you choose, and the lender decides whether the result fits its guidelines.
Mortgage insurance is part of step 3. Insurance is required above 80% LTV. You can ask to cancel it at 80% of the original value, with good payment history, no subordinate liens and no decline in value. The servicer must end it automatically at 78%. If a low value pushes you from 79% to 83%, you now carry insurance you had planned to avoid. The premium is not a fixed number. It varies by lender, program, leverage and credit, so look for the actual figure on your Loan Estimate rather than assuming one.
Path One: Ask for a Reconsideration of Value
Fannie Mae's rules now require lenders to let borrowers appeal a value they believe is unsupported. Fannie Mae's Appraiser Update lays out the process. The lender does its own appraisal review first. An underwriter or appraisal specialist reviews your request and checks that it has enough evidence before it goes to the appraiser. Only one borrower-initiated request is allowed per appraisal.
One shot. Make it count.
A useful request is specific. It lists recent sales close to the home, similar in size and condition, that the appraiser did not use. It flags factual errors in the report: square footage, bedroom count, a finished basement left out, upgrades missed. Opinions about what the house "feels worth" do not move values.
Two limits matter. First, any change to the report must come from the appraiser who wrote it, per Fannie Mae's appraisal quality rules. The lender cannot edit the number. Second, Fannie Mae's reconsideration FAQ says the lender decides whether to accept the appraiser's conclusions. Nothing guarantees the value moves, and sometimes it does not.
Honestly, the strongest requests come on files where an obvious comparable was missed. Where the market simply softened, expect little change.
Path Two: Shrink the Loan
If the value stands, the maximum loan falls with it. On a limited cash-out refinance at the cap, the lender recalculates the ceiling off the new value and the loan has to come down to fit.
The pinch lands on closing costs. Many borrowers roll costs into the new balance. When the ceiling drops, that headroom can vanish, and you may have to pay those costs in cash at closing. You can also bring cash in to pay the balance down. That is a "cash-in" refinance. It keeps the program and the loan type, but it asks for money you may not have planned to spend.
Quick break-even check on your own file. Take your payoff balance plus the costs you planned to finance. Divide by the cap. The result is the minimum appraised value the deal needs. The gap between that number and what your home appraised for tells you how much cushion you had and how much cash a miss costs you. Lenders do this arithmetic the moment the report lands.
Path Three: Change the Program or Transaction Type
This path has a trap in it. If you restructure so cash goes to you, the file may no longer be a limited cash-out.
A conventional limited cash-out lets the new loan pay off the existing first mortgage and fund closing costs, with only small cash back. Under Fannie Mae's current cash-back cap, that cash back can't exceed the lesser of 1% of the new loan balance or $2,000. Older websites still show the former formula, so check the date on anything you read.
Paying off a second lien that was not used to buy the home also changes the file. Fannie Mae's Selling Guide allows only purchase-money second liens inside a limited cash-out. Anything else makes it a cash-out refinance.
The consequences are large. Conventional cash-out tops out at 80% LTV on a one-unit principal residence and 75% on two- to four-unit principal residences, second homes and investment property. Seasoning also applies: the first mortgage being paid off must be at least 12 months old, note date to note date, and a borrower must have been on title for 6 months, with exceptions for delayed financing, inheritance and legal awards. So switching lanes after a low appraisal usually means a lower ceiling, not a higher one. Treat it as a last resort, not a rescue.
Path Four: Pause or Withdraw
You can stop. If you do, you are still entitled to a copy of the appraisal. The CFPB's rule on appraisal copies requires lenders to provide it at no charge, whether credit is extended, denied or withdrawn. Waiting and letting the market or your balance catch up is a legitimate decision. So is refinancing later with a different structure.
Small Miss or Large Miss?
The size of the shortfall decides which path is sensible.
| Size of miss | Typical effect | Usual first move |
|---|---|---|
| Small (about 1-2%) | Loan slightly over cap | Trim loan or pay costs in cash |
| Moderate (about 3-5%) | Costs can't be financed; insurance band may shift | Reconsideration request, then resize |
| Large (above 5%) | Cap may be out of reach | Rethink the refinance or wait |
Those bands are rules of thumb for explaining the math, not program limits.
Your Options in Order
A clean sequence saves you from burning your one reconsideration request.
| Step | Action | Trade-off |
|---|---|---|
| 1 | Read the report for factual errors | Free, and it can settle things |
| 2 | Submit one well-documented reconsideration | One shot per appraisal |
| 3 | Pay down or pay costs in cash | Uses savings |
| 4 | Accept a smaller loan | May miss your goal |
| 5 | Change program or transaction type | Usually a lower cap |
| 6 | Wait and refile later | Keeps your current loan |
Where the General Rule Breaks
Government streamlines don't test value. An FHA Streamline on an existing FHA loan carries no appraisal requirement and uses a net tangible benefit test instead, as HUD's streamline page describes. A VA IRRRL on an existing VA loan works the same way, with no VA appraisal, a 0.5% funding fee unless exempt, and seasoning of the later of 210 days and six payments. A low value can't break those loans, though a lender may still add its own requirements. FHA rate-and-term, the option for a non-streamline FHA borrower, goes to 97.75% LTV with an appraisal, so it is exposed to the same value risk as a conventional loan. Final terms depend on the lender's guidelines, the property type, and the borrower's complete credit picture.
Occupancy changes the cap. The same appraisal gap hurts more on a second home or investment property, where the caps sit lower than on a principal residence. Occupancy decides the leverage.
Manufactured homes carry their own limits. Fannie Mae's eligibility matrix shows different LTVs for manufactured housing, so a low value reads differently there.
Jumbo loans. Above the conforming limit, the jumbo lanes take over, with leverage to 90% and loans to $5,000,000, and a 660 decision score. The same cap-and-value logic applies.
Mortgage insurance can end the problem. On some files, the sensible answer to a modest miss is accepting insurance above 80% and letting it cancel at 80% later, rather than bringing in cash.
Why the Number Came In Low
Causes matter because each one points to a different remedy.
| Cause | What to check | What to submit |
|---|---|---|
| Missed comparable sales | Sales near you in the same range | A short list of comps |
| Wrong home facts | Square footage, rooms, upgrades | Documentation of the facts |
| Condition issues | Repairs flagged in the report | Proof of completed work |
| Market softening | Whether nearby values fell | Little to submit; plan to resize |
Plan Ahead With a Cushion
Don't size the request at the cap. Leave room. If the loan sits a few points under the ceiling, a modest miss breaks nothing. Before the appraiser visits, gather a list of improvements with dates, note anything the public record may have wrong, and make sure the appraiser can reach every room.
Know your seasoning too. Files that assume it away get kicked back.

Frequently Asked Questions
Can I refinance if the appraisal comes in low?
Often yes, with a smaller loan or more cash at closing. The program cap is a share of the new value, so the ceiling drops and the loan must fit under it. Mortgage insurance may apply above 80% LTV. Everything is subject to lender guidelines and full file review.
How many times can I challenge a low appraisal?
Once per appraisal on a conventional loan, under Fannie Mae's process. The lender reviews the request first, then the original appraiser decides. Only that appraiser can change the report. Put your best comparable sales and any factual corrections into that single request.
Do FHA Streamline and VA IRRRL loans care about a low appraisal?
Generally no. Both are for existing government loans and are built around net tangible benefit rather than value. FHA Streamline carries no appraisal requirement, and the VA IRRRL has no VA appraisal. A lender can still add its own conditions, so confirm before assuming.
Will a low appraisal make me pay mortgage insurance?
It can, because insurance is required above 80% LTV, so a lower value that pushes the loan past that line triggers it. You may request cancellation at 80% of the original value with good payment history, no subordinate liens and no decline in value. The servicer must end it at 78%. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
Can I switch to cash-out to fix a low appraisal?
Rarely helpful. Cash-out caps are lower, at 80% on a one-unit principal residence and 75% on the other property types, and seasoning rules apply. Switching usually shrinks the ceiling further. Cash going to you, or a non-purchase second lien being paid off, turns a limited cash-out into a cash-out.
