The Quick Read: There is no single ratio limit for an FHA cash-out refinance. The limit depends on how your file is underwritten. A computer scores most files, and that finding governs. A file that gets kicked to a human underwriter lands on a fixed ladder, from a base of 31/43 up to 40/50 when the borrower documents strong compensating factors.
Key Takeaways
- Two ratios matter: housing payment to gross income, and total debts to gross income. The base pair is 31/43.
- The automated finding governs most files. A “Refer” result sends the file to manual underwriting, which is not a denial.
- Documented compensating factors can lift manual limits as high as 40/50 at the top tier.
- Cash-out reaches 80% loan-to-value on a home you have owned and lived in for 12 months before the case number.
- Taking cash out raises your payment, so it raises both ratios. Taking less cash is the fastest lever.
Key Terms Defined
Front-end ratio (housing ratio): Your proposed total housing payment divided by your gross monthly income. The housing payment includes principal, interest, taxes, insurance and FHA mortgage insurance.
Back-end ratio (total ratio): Your housing payment plus your other monthly debts, divided by gross monthly income.
Loan-to-value (LTV): The loan amount divided by the home’s appraised value. For cash-out, the cap is 80%.
Automated underwriting: Software scores your credit and application data and returns a risk finding, such as Accept or Refer.
Manual underwriting: A human underwriter reviews the file against a fixed ratio matrix. Compensating factors can lift the limits.
Compensating factors: Documented strengths, such as cash reserves or a small payment change, that justify higher ratios.
Decision credit score: The score the lender uses to place you in a tier. Pricing and available terms vary by lender, borrower profile, property type, and full underwriting review.
Overlay: A lender’s own rule that is stricter than the FHA minimum.
Reserves: Savings left after closing, counted in months of mortgage payments.
What Decides Which Ratios Apply?
One fork decides it: did the file stay automated, or did it go manual?
Here is how the two paths compare.
| Factor | Automated path | Manual path |
|---|---|---|
| Who decides | Scoring software | A human underwriter |
| Trigger | Default for cash-out | Refer finding, downgrade, or no score |
| Ratio limits | Whole risk profile, no single cap | 31/43 base, up to 40/50 |
| Documentation | Standard file | Standard file plus factors |
Most cash-out files start on the automated path, though files with no credit score begin in manual underwriting instead. Lenders submit the file after they pull credit, document income, assets and debts, and determine your decision score. The software weighs the whole picture. It looks at credit history, the size of the new payment, and how much equity stays in the home.
The program itself is described on Lendmire’s FHA cash-out refinance program page. This article covers only the ratio side.
Across the wholesale programs Lendmire places FHA files with, the automated finding governs most files. Manual underwriting is the exception. It still decides the outcome often enough that you should know the ladder.
How the Underwriting Runs, Step by Step
Think of the process as a short sequence.
1. Eligibility screen. FHA cash-out is for a home you live in as your main residence. A co-borrower who does not live there cannot add income to qualify the loan.
2. Ownership and payment history. You need to have owned and occupied the home for 12 months before the case number. Lenders also review your recent mortgage payments. A clean record matters.
3. Credit and documents. The lender pulls credit, sets your decision score, and verifies income, assets and debts.
4. Automated scoring. The file goes through HUD’s TOTAL Mortgage Scorecard, an algorithm HUD built to evaluate credit history and application data. HUD says forward mortgages must be scored through it, except streamline refinances and assumptions. Cash-out is not exempt.
5. The finding. An Accept can stay automated. A Refer moves the file to manual review.
6. Appraisal. The appraised value sets the ceiling at 80% of the adjusted value.
7. Closing. The new loan pays off the old mortgage. You receive the difference as cash.
What decides the result? Mostly five things: the finding, your decision score, any documented compensating factors, the appraisal against the 80% cap, and lender overlays.
How Do the Ratios Work Under Automated Underwriting?
Automated approvals do not carry one published maximum. The software judges the whole risk profile, so a borrower with strong credit, savings and a modest payment change can be approved at ratios that would fail on the manual ladder.
This is why you see conflicting numbers online. Some pages say 43%. Others say the limit is much higher. Both can be right, because they describe different paths.
Do not treat a high automated result as a promise, though. The lender still applies its own overlays. It also reviews occupancy, payment history and the appraisal before it moves forward.
Here is what tends to move an automated finding:
- Your decision score and the depth of your credit history
- The size of the payment change after the cash-out
- Reserves left after closing
- Stability of income
- How much equity remains in the home
What Is a Manual Underwriting Referral?
A “Refer” is not a decline. It means a human underwriter must apply HUD’s matrix. According to HUD Mortgagee Letter 2014-02, manual loans include the following groups:
- Borrowers with no credit score
- Files that get a Refer from the scorecard
- Files that get an Accept but are downgraded to Refer by the underwriter
Under manual rules, the limit depends on your decision score and on your compensating factors. The base pair is 31/43. That means your housing payment should stay at or under 31% of gross income. Your total debts should stay at or under 43%.
Documented compensating factors raise those limits in steps. At the top tier, the pair reaches 40/50. Most borrowers do not get there without strong support in the file.
Common compensating factors include:
- Cash reserves after closing
- A small increase over your current housing payment
- Little or no other debt
- Substantial documented income beyond what you already counted
The same letter sets reserve requirements. They are higher for 3-4 unit homes than for 1-2 unit homes. Your lender can tell you the current months required. Reserves are one of the few levers you can pull before applying. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.

How Do You Calculate Your Own Ratios?
You can estimate both ratios with four steps.
1. Find gross monthly income. Use income before taxes. Lenders document it with pay records and similar proof.
2. Estimate the new housing payment. Add principal and interest on the new loan, taxes, homeowners insurance, and FHA mortgage insurance. Your lender can supply this figure.
3. Divide housing by income. That is your front-end ratio.
4. Add monthly debts and divide again. Include car loans, student loans, credit card minimums and other required debts. That is your back-end ratio.
Here is a quick way to tell which ratio binds. If your front-end ratio is over its limit but your back-end is comfortable, the housing payment is the problem. Taking less cash helps most. If the back-end is over but the front-end is fine, other debts are the problem. Paying them off at closing may fix it.
Debts paid off with cash-out proceeds at closing generally leave your ratio, which is why some borrowers use proceeds to clear high-minimum accounts. Your lender confirms how each debt is counted.
What Does a Cash-Out Do to Your Ratios?
It raises your payment, which raises both ratios. Four forces drive that.
- A bigger balance. You borrow more than you owe today.
- Mortgage insurance. FHA charges an upfront premium of 1.75% of the base loan, which is typically financed into the balance. It also charges an annual premium between 0.15% and 0.75% of the balance, depending on term, loan amount and LTV. At or below 90% LTV on a thirty-year loan, the annual premium ends after eleven years.
- A reset term. A new loan starts a new term. A CFPB research note says a typical cash-out loan has a longer term and larger monthly payment than the paid-off mortgage.
- Closing costs. CFPB staff research says cash-out closing costs can be substantial. They include origination fees, appraisal fees and title insurance. Costs rolled into the loan shrink the cash you receive.
Cash available is the 80% cap, minus your payoff, minus costs. Two borrowers with the same equity can get different answers. Income and other debts decide it.
A Walk-Through: Refer, Then Rescue
Picture a homeowner with a decision score above 580. The home has been owned and lived in for well over 12 months. The existing balance is about 55% of the appraised value. The owner wants a new loan near 78% of value.
Run the ratios in percentages of gross income. Before the refinance, housing sits near 24% and total debts near 38%. After a large cash-out, housing climbs to about 34% and total debts to about 48%.
The automated finding comes back Refer. The ratios are heavy and reserves are thin. On the manual ladder, 34/48 sits above the base pair. It would need a strong set of compensating factors, and this file does not have them.
The owner has three moves:
1. Take less cash. Cutting the new loan to a lower share of value drops the payment. Housing falls toward 31%.
2. Pay off debts at closing. Clearing small accounts drops other monthly debts. In this picture, other debts fall from 14% of income to about 4%.
3. Document reserves. Savings left after closing strengthen the file.
After those changes, the ratios land near 31/35. That sits inside the base pair, with room to spare. The outcome is still the lender’s call after full file review. It is not a commitment to lend. But the path is clear: the borrower changed the file instead of arguing with the result.
This is a genuine toss-up for many borrowers. A larger cash-out solves one problem and creates another. Many files do better with a smaller draw than first planned.
Why Do Quoted Ceilings Differ?
Sources disagree because they describe different things. The usual reasons:
- Different paths. One page may describe automated approvals. Another describes manual.
- Different score bands. Manual tiers shift with the decision score.
- Different factors. The same score gets a higher limit with documented compensating factors.
- Overlays. A lender can set stricter limits than FHA does. Some lenders also set a higher score floor. This is why two lenders can give different answers on the same file.
- Old information. FHA has changed cash-out rules before. HUD Mortgagee Letter 2019-11 lowered the cash-out LTV cap to 80% from a higher figure. The letter says HUD did so to reduce risk to the FHA insurance fund. Pages that still say a higher cap are out of date.
A common myth is that one FHA ratio rule covers everything. It does not. The honest answer is “it depends, and here is exactly on what.”
Conventional cash-out has its own tradeoffs. For a side view, see Lendmire’s piece 5 Myths About Qualifying for a Conventional Cash-Out Refinance.
Where the Rule Bends
A few cases change the picture.
- No credit score. These borrowers are manually underwritten from the start. The tighter base ratios apply, and compensating factors do not lift them. Note that the wholesale programs Lendmire works with start at a 580 decision score.
- Non-occupant co-borrower. Their income cannot be used to qualify a cash-out. That differs from FHA purchase loans, where a non-occupant co-borrower is allowed.
- Home with an accessory unit. Rental income from an accessory unit does not count toward qualifying for cash-out.
- 3-4 unit homes. Older HUD reference guidance calls for a self-sufficiency test and more reserves. Check current rules with your lender.
- Free-and-clear homes. A home with no mortgage can still be refinanced as cash-out. The same archived guidance supports this.
- Inherited homes. Some lenders waive the occupancy wait for an inherited home that was never an investment property. Overlays vary.
- Second homes and rentals. They are not eligible. Occupancy decides the leverage.
- Hawaiian Homelands (Section 247). These loans are exempt from the 80% cap.
- Streamline refinance. It is a different product. It refinances an existing FHA loan with no appraisal and a limited credit review. Do not mix its rules with cash-out.
If you hold a current FHA loan and just want a lower payment or better terms, a streamline may fit better. If you need equity out, cash-out is the tool. And if you want a smaller step, the FHA rate-and-term with an appraisal reaches 97.75% on a principal residence occupied for the previous twelve months.
What If You Don’t Qualify?
Work the list in order of impact.
1. Take less cash. This lowers the payment and both ratios.
2. Pay down or pay off debts. Revolving accounts help most. Paying off debts at closing may count.
3. Build reserves. Savings left after closing are a strong compensating factor.
4. Raise your score. A higher decision score opens higher manual tiers.
5. Check the appraisal. A higher value leaves more room under the 80% cap.
6. Ask about overlays. A different lender may use looser rules than the one that declined you.
Be careful about turning unsecured debt into mortgage debt. CFPB research notes that securing non-mortgage debt with your home can put the home at risk if payments become unsustainable. Defaulting on a credit card is unlikely to cost you the house. Defaulting on the mortgage can.
Tax treatment can depend on your situation; borrowers should speak with a qualified tax professional before relying on any deduction or credit.
Frequently Asked Questions
Is there a maximum DTI for an FHA cash-out refinance?
Not one number. On the manual path, the base pair is 31/43, and compensating factors can lift it up to 40/50 at the top tier. Automated approvals have no single published cap, because the software weighs your whole profile. Lender overlays can be stricter than either.
Does an automated approval override the manual limits?
Yes, when the file stays automated. The manual ladder applies only if the finding is Refer, the underwriter downgrades the file, or you have no credit score. Even then, the lender reviews occupancy, payment history and the appraisal.
What happens if I get a Refer finding?
The file goes to a human underwriter who applies the manual matrix. It is not a decline. You can strengthen the file with reserves, lower debts or a smaller cash-out amount.
Do paid-off debts help my ratios?
Yes, they can. Debts paid off at closing from the proceeds generally leave your monthly obligations, which lowers the back-end ratio. Your lender confirms how each account is treated. Paying off debts does not shrink the housing payment, so it will not fix a front-end problem.
Is 80% loan-to-value enough to be approved?
No. The 80% cap is a ceiling. It is not a promise. The lender also reviews occupancy, payment history, credit, income, the new payment and the appraisal, subject to lender guidelines and full file review.
