The Quick Read: An FHA cash-out on a duplex replaces your whole first mortgage with one new, larger FHA loan, and you receive the difference in cash. It does not sit on top of your current loan, so a low-rate mortgage disappears when the new one funds. You must live in one unit, and the new loan generally tops out at 80% of the appraised value. Subject to lender guidelines and full file review, the other unit’s rent can help you qualify.
Key Takeaways
- The new loan pays off your old first mortgage. You cannot keep the old rate and add FHA cash on top.
- The home must be your principal residence, and you must have owned and lived in it for 12 months before the case number is assigned.
- Maximum financing is 80% of the home’s value. Cash is what remains after the payoff and costs.
- A duplex is appraised as a two-unit property, and rent from the other unit is counted at a discount.
- Whether the trade is worth it depends on how much your current loan’s terms are worth to you.
What Happens to a Locked-In Mortgage
Your old first mortgage ends. A cash-out refinance swaps it for a bigger loan and hands you the difference. That is true whether your current loan is FHA, conventional, or something else. A home with no mortgage at all can also be cashed out, in which case there is no old loan to give up.
FHA cash-out estimate
Seeded with an example value, a balance to match, and a round cash request; change any field.
Editable benchmark: 7.18% as of November 5, 2026 · Freddie Mac 30-year average via FRED®. A conventional market reference, not an FHA cash-out refinance quote.
Illustrative starting assumptions: a $350,000 home value, a $193,000 current balance, the FHA cap on a principal residence with the upfront premium financed, a thirty-year term at the current Freddie Mac benchmark, and property taxes and insurance estimated at typical national rates. Every field is editable.
An illustration, not a Loan Estimate, an approval, a quote, or a commitment to lend. The rate shown is the weekly Freddie Mac thirty-year conventional benchmark, used as a market reference; an FHA cash-out is priced by the lender at lock, and this is not an FHA cash-out refinance quote. HUD’s cap limits the base loan; the upfront premium is financed on top of the capped base loan; the monthly premium for the first year follows the snapshot’s schedule. Cash available means the base loan the cap permits less the balances retired, before closing costs, which this calculator leaves out. The line figure applies the line program’s combined loan-to-value ceiling to the same value and balance. Taxes and insurance are estimates you can edit. Licensed in sixteen states for consumer mortgages.
For a borrower with a low rate, “locked-in” means the rate you have is the thing you surrender. Your new loan gets new terms across the whole balance, not just the cash you pull out.
This is the first question to settle before any paperwork. The core trade is simple: you get access to equity, and you reset the entire loan to do it.
A practitioner’s note. Borrowers who regret it often took cash for a vague reason while holding a loan they would have been better off keeping. Same program, very different outcomes.
Does FHA Cash-Out Work on a Duplex?
Yes, with conditions. FHA covers one- to four-unit homes, but only when you live in the property. On a duplex, that means you occupy one unit and the other is yours to rent.
Three conditions matter most:
1. Owner-occupied principal residence. Second homes and pure rentals do not qualify for this cash-out. Occupancy decides the leverage.
2. Twelve months of ownership and occupancy. The clock runs back from the date the FHA case number is assigned. A recently purchased duplex generally has to wait.
3. A clean recent payment record. Lenders document that your mortgage payments were made on time over the prior year.
FHA is a program for people who live in what they own, so renting the second unit to a tenant fits the rules while you occupy the first.
How the Loan Is Underwritten, Step by Step
Here is the sequence a lender follows, in plain order.
1. Eligibility screen. The lender confirms you own the duplex, live in it, and meet the 12-month test. A non-occupant co-borrower’s income cannot be used on a cash-out, even though a purchase allows one.
2. Payment history. The lender pulls your mortgage history and checks that it is current. The existing lien’s age and payoff are reviewed too.
3. Credit review. Across the wholesale programs a broker places FHA loans with, the starting point is a 580 decision score. Some lenders set a higher floor. After a chapter 7 discharge, HUD’s waiting period is two years. After a foreclosure, it is three years. Those are HUD’s rules, not a promise from any lender.
4. Appraisal. A duplex is appraised on the small residential income property form. It reports the value and the market rent for each unit. HUD’s guidance on rental income names that form for two- to four-unit homes.
5. Income and ratios. The lender compares your housing cost and total debts to your income. The base pair is 31/43. Documented compensating factors can stretch that to 40/50 at the top tier, and the automated underwriting finding governs most files.
6. Payoff and cash math. The lender gets a payoff statement for every existing mortgage. The new base loan is capped at 80% of value. Whatever remains after payoff and costs is your cash.
7. Closing and cooling-off. You sign, then a federal cancellation window applies before funds are released. More on that below.
None of this guarantees approval. The outcome rests on the appraised value against your existing balance, your credit file, your ratios, and the county loan limit.
How Rent From the Other Unit Counts
It helps, but not dollar for dollar. HUD’s rental-income policy counts about 75% of the rent, not all of it, to allow for vacancy and upkeep. That policy is laid out in Mortgagee Letter 2023-17.
Say your tenant pays a solid rent for the second unit. The lender counts only a portion toward your qualifying income. The appraiser’s market-rent figure and your lease both feed that number. Where there is no rental history, the lesser of the two is the usual anchor.
Two cautions. First, the same letter says rent from an accessory dwelling unit on a one-unit property cannot be used to qualify for a cash-out. A true duplex is a different property type, but a duplex with a third, add-on unit can be treated differently. Second, confirm with your loan officer at the start how the lender applies these rental rules to your particular file.
Duplexes also avoid a hurdle that three- and four-unit homes face. Those larger properties have to pass a self-sufficiency test and carry extra reserves. A duplex generally does not.
How Much Cash Can You Actually Take?
The ceiling is 80% of the appraised value. That is HUD’s cap on cash-out for loan-to-value (LTV, the new loan as a share of the home’s worth) and combined loan-to-value, per HUD’s FHA knowledge base. It replaced an older 85% limit. The cap is a ceiling, not a promise of that amount.
Run the numbers in percentages. Picture a duplex that appraises at 100% of its value. Your current mortgage balance equals 55% of that value. The new loan can reach up to 80%. That leaves up to 25 points of the home’s value as gross cash.
Then subtract the costs:
- Closing costs, which appear on your Loan Estimate.
- The upfront mortgage insurance premium, which is 1.75% of the base loan and is financed into the balance.
- Any other liens being paid off.
What is left is your check. The upfront premium is added to the loan, so it raises your balance even though you never write a check for it.
Two other limits apply. The first mortgage plus any second liens cannot exceed the county loan limit. And any second lien sitting behind an FHA first counts toward that 80% combined cap. County limits change every year, so ask your loan officer for the figure that applies to your county.
What FHA Mortgage Insurance Means for You
You pay two kinds. The upfront premium is 1.75% of the base loan, and it is financed. The annual premium runs between 0.15% and 0.75% of the balance, depending on term, loan amount, and LTV.
Duration matters here. On a thirty-year loan above 90% LTV, the annual premium lasts for the full term. At or below 90% LTV, it ends after eleven years. Because a cash-out tops out at 80%, a thirty-year cash-out generally falls in the second group. Your lender confirms how it applies to your file.
Your old mortgage insurance, if you had it, ends with the old loan. The new loan starts its own.
Cash-Out vs. Keeping Your Loan: The Decision Table
You have more than two paths. This table compares them side by side.
| Option | What happens to your first loan | Cash access |
|---|---|---|
| FHA cash-out | Fully replaced | Lump sum at closing |
| Home equity loan | Stays in place | Lump sum, second lien |
| HELOC | Stays in place | Credit line, second lien |
| Keep as is | Stays in place | None |
Home equity loans and HELOCs are separate second mortgages. They come from lenders and are not FHA products. The Consumer Financial Protection Bureau notes that a cash-out replaces your mortgage with a bigger one, and that depending on the terms, it can cost more or less than a HELOC. No option wins on cost by default.
Here is the break-even logic, without pricing. A cash-out makes the most sense when the use of the cash earns or saves you more than the value of your old loan’s terms. A second lien leaves the first loan alone, but you carry two payments and a second set of terms. Keeping your loan costs nothing and gives you nothing.
Where the General Rule Breaks
Real files hit edges. These are the common ones.
- You bought within the last year. The 12-month ownership and occupancy test generally blocks a standard cash-out. Wait it out.
- You moved out and rented both units. The home is no longer a principal residence. This cash-out is off the table, and occupancy decides the leverage.
- Your current loan is already FHA. You can still cash out, but there are other FHA refinances to compare. The FHA Streamline refinances an existing FHA loan with no appraisal and a limited credit review. It requires a net tangible benefit, and the mortgage insurance premium continues. It gives no cash.
- You only want a better term, not cash. The FHA rate-and-term refinance, with an appraisal, reaches 97.75% on a principal residence occupied for the previous twelve months. A cash-out is a different product.
- Your current loan is conventional. A cash-out can pay it off. HUD’s definition covers any mortgage, FHA or not, per HUD Handbook 4000.1.
- You own the duplex free and clear. You can still cash out. The payoff step is just skipped.
- A third unit exists. A duplex with an add-on unit may be treated differently. Raise it before the appraisal.
- The county limit binds. In a high-cost area the limit may be higher. In a lower-cost one it may cap you below 80%. Ask which applies.
The Three-Day Cooling-Off Window
You get to change your mind. On a refinance of your primary home, you have until midnight of the third business day to cancel. Saturdays count, while Sundays and legal public holidays do not. The CFPB explains when the window starts.
Funds are not released until the window ends. That is the reason cash-out is a poor fit for a true emergency.
If you cancel, you still owe your original loan. The old mortgage is not erased. The only exception is a bona fide personal financial emergency, in which case you may waive the window with your own written statement.
Key Terms Defined
Cash-out refinance: A new mortgage that pays off your old one and gives you the difference in cash.
LTV (loan-to-value): The loan balance as a percentage of the home’s appraised value.
Combined LTV (CLTV): All loans against the home, first and second liens together, as a percentage of value.
Owner-occupancy: You live in the property as your main home. On a duplex, that means one of the two units.
Upfront and annual mortgage insurance premium (MIP): FHA’s insurance charges. One is financed at closing, and the other is billed over time on the balance.
Decision score: The credit result a lender’s underwriting system uses to judge a file, not just a single bureau score.
Right of rescission: Your three-business-day window to cancel a refinance of your primary home.
What the Decision Looks Like in Practice
Start with the purpose. Name what the cash will do. A repair that raises the property’s value, a payoff of debt that costs more than your mortgage, and a one-time need are different cases from “extra cushion.”
Then compare three things on paper: what you give up in the old loan, what you add in mortgage insurance and costs, and what the cash earns or saves. Your Loan Estimate shows the costs line by line, so you can compare offers on full terms rather than a single number.
Then test your leverage. At up to 80% LTV, you keep at least 20% equity. A drop in value or a higher balance later narrows that cushion. Be honest about whether you would be comfortable with a bigger balance on both sides of the duplex. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
If you are weighing a cash-out refinance against keeping the loan you have, Lendmire can help you compare the programs and the equity each one reaches.
Frequently Asked Questions
Can I keep my low rate and still take FHA cash-out on my duplex?
No. The cash-out loan replaces your whole first mortgage, so the old rate and term go away. If keeping the first loan matters most, a second lien from another lender leaves it in place. Any second lien behind an FHA first still counts toward the 80% combined cap.
Do I have to live in the duplex?
Yes. Standard FHA cash-out is for your principal residence, so you live in one unit. You must have owned and occupied the home for the 12 months before the case number. You can rent the other unit, and its rent can help you qualify at a discount.
What credit score do I need?
A 580 credit score is the usual starting point. Some lenders set a higher floor. HUD’s waiting periods after credit events are two years from a chapter 7 discharge and three years from a foreclosure. Everything stays subject to lender guidelines and full file review.
Does the upfront mortgage insurance premium come out of my cash?
It is financed into the loan, so it raises your balance rather than being paid in cash. The premium is 1.75% of the base loan. You still see it on your Loan Estimate and Closing Disclosure, along with every other cost.
Is a cash-out cheaper than a HELOC?
It depends on the terms. A cash-out resets your whole loan and often carries closing costs. A HELOC leaves your first mortgage alone but adds a second lien. Compare the full terms of each, not a single feature.
