The Quick Read: An FHA cash-out refinance on a duplex you live in replaces your entire current mortgage with one new loan. You get the difference in cash. That means the low rate you have now is gone, because the new terms apply to the whole balance. The loan tops out at 80% of the home’s appraised value, and you must have owned and lived in the duplex for the prior 12 months.
Key Takeaways
- A cash-out refinance is one new first mortgage. It is not a second loan stacked on top of your old one.
- The FHA cash-out is limited by a maximum LTV (loan-to-value, the loan as a share of the home’s value). Any second lien that stays in place counts toward that cap.
- You must live in one unit as your main home, and you must have owned and occupied the duplex for 12 months before the case number is assigned.
- The other unit’s rent can help you qualify, but only to the extent the lender can count it.
- If protecting your current low rate is the priority, a loan that sits behind your first mortgage may fit better than a cash-out. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
What Does “Locked-In Mortgage” Mean Here?
“Locked-in” is a borrower’s phrase, not a loan term. It means you hold a first mortgage with terms you would not get today, usually a low rate, and you feel stuck with it. Moving or refinancing would trade that loan for current terms.
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.
That is different from locking the terms of a new loan during the application. Here we are talking about the old loan you already have and what happens to it.
With an FHA cash-out, the old loan is paid off at closing. The new loan carries a new note, a new term, and a fresh payment schedule. The cash you take comes from the same new loan. So you cannot keep your low rate on your existing balance and borrow the extra at a different rate. The whole balance moves to the new terms.
That is the trade-off at the heart of this topic. It is also why many duplex owners decide against a cash-out once they see the full picture.
How Does an FHA Cash-Out Work on a Duplex, Step by Step?
Lendmire is a mortgage broker, so lenders review and approve the file. Here is how it unfolds for a two-unit home. Everything is subject to lender guidelines and full file review.
1. The eligibility check. The lender confirms you have owned the duplex and lived in it as your principal residence for 12 months before the FHA case number is assigned. The case number is the ID that FHA gives the loan file.
2. The payment history check. The lender reviews how you have paid the mortgage you are about to replace. A recent late payment can stop a cash-out cold.
3. The appraisal. An appraiser values the whole duplex. That value sets the ceiling, since the loan cannot exceed 80% of it. When rent from the second unit is used to qualify, the appraisal also supports the market-rent figure.
4. Sizing the loan. The new loan pays off your first mortgage, covers closing costs and the upfront mortgage insurance premium, and leaves your cash. County loan limits apply and can cap the loan before the 80% test does.
5. Underwriting. The lender reviews your credit, income, assets, and debt ratios. The new mortgage insurance payment counts in those ratios.
6. Disclosures and closing. You receive a Loan Estimate early on and a Closing Disclosure before you sign. Compare the numbers on them line by line.
How Much Cash Can You Actually Take Out?
Less than most owners expect. The cap is 80% of the appraised value, and the cash is what remains after the loan pays everything else.
Run the numbers in percentages. Say your duplex appraises at 100% of its value. Your current first mortgage is 55% of that value, and you have no other liens. The most the new loan can reach is 80%. Subtracting 55% from 80% leaves 25% of the value of room, before closing costs and the financed insurance premium come out.
Now change one fact. Suppose you also have a home equity line (a revolving loan secured by the house) that is 10% of the value, and it stays in place. That line counts toward the same 80% cap, so the 80% limit covers the first mortgage and the line together. Your room shrinks from 25% to 15% of value, before costs. Many owners are surprised by this, because the equity on paper looks larger than the equity the program lets them reach.
The county loan limit for a two-unit home is the other ceiling. It changes every year, so check HUD’s current figures for your county rather than relying on an old number.
Why Is the Cap 80%?
FHA used to allow higher leverage on cash-out loans. Then HUD Mortgagee Letter 2019-11 lowered the maximum LTV and combined LTV on cash-out refinances to 80% of the adjusted value. HUD pointed to the fast growth in cash-out endorsements and said the goal was to strengthen the equity position behind those loans.
The practical effect is simple. You keep at least 20% equity after closing, counting every lien on the home. If you read an older guide that quotes a higher cap, it is out of date.
What Mortgage Insurance Comes With It?
FHA loans carry two kinds of mortgage insurance, and both apply here.
- The upfront premium is 1.75% of the base loan. It can be financed into the loan, so you do not pay it out of pocket, but it raises the balance. HUD Mortgagee Letter 2023-05 sets the schedule.
- The annual premium is charged monthly. Depending on term, loan amount, and LTV, it falls between 0.15% and 0.75% of the balance per year.
A cash-out is capped at 80% LTV, so it lands in the at-or-below-90% tier. On a thirty-year loan in that tier, the annual premium ends after eleven years. On a loan in the higher-leverage tier, it lasts for the full term. This is a program fact, not a price quote. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
One more point matters for a duplex owner. The premium counts in your debt ratios, so it affects how much you can qualify for.
How Does the Rental Income From the Other Unit Count?
It can help, but it is not a blank check. The lender generally counts only part of the rent from the unit you do not live in. The figure depends on the appraiser’s market rent and on the lease or rental history you can document. Expect to provide leases and possibly other records.
Because you live in one unit, this is an owner-occupied loan. Your income and credit are underwritten the way any home buyer’s are. The rent is a supporting piece, not a replacement for your own income.
The ratio picture looks like this. The base pair on FHA is 31/43, with no compensating factors. That means your housing payment is up to 31% of income and your total debts are up to 43%. Documented compensating factors, such as strong savings or a low-risk payment history, can raise the limits, reaching 40/50 at the top tier. The automated underwriting finding governs most files. Credit score requirements apply as well, and some lenders set a higher floor than others.
One thing is worth checking before you apply: whether the cash you take out can count toward reserves (savings left over after closing). Guidelines differ by lender, so ask early.
Where Does the General Rule Break?
| Situation | Does a standard FHA cash-out fit? |
|---|---|
| You live in one unit, owned 12+ months | Yes, if you meet the other tests |
| You moved out and rent both units | No, it is no longer your principal residence |
| You own it free and clear | Yes, it can still be a cash-out |
| You inherited the duplex | Possibly; see below |
| You owned it under 12 months | Not yet |
| You hold a HELOC on the property | Yes, but the HELOC counts toward the 80% cap |
Inherited property. The usual rule is that you must have owned and occupied the home for 12 months before the case number. Some inherited-property files may be treated differently, but only if you have not treated the property as an investment since inheriting it, and the lender decides after reviewing the file. If you rented it out after the inheritance, you would generally need to live in it for 12 months first. Lenders read these files closely.
An existing loan that is not FHA. The loan you are replacing does not have to be an FHA loan. A conventional first mortgage can be paid off with an FHA cash-out.
Two separate clocks. The 12-month ownership and occupancy test is one check. The payment history review is another. You can pass one and fail the other.
Streamline refinances. The FHA Streamline refinances an existing FHA loan with no appraisal and a limited credit review. It requires a net tangible benefit and brings no cash out. The FHA rate-and-term refinance, with an appraisal, reaches 97.75% on a principal residence you occupied for the previous twelve months. Neither gives you cash.
Is Giving Up the Low Rate Worth It?
It depends on what the cash does for you. This is the honest answer, and the right answer changes by borrower.
Consider a duplex owner who needs money to fix a failing roof or heating system. The cash solves a real problem, and the cost of the new terms may be worth paying. Compare that to an owner who wants cash for a vacation or to pay off credit cards. The CFPB explains that a cash-out replaces your mortgage with a bigger one and gives you the difference. Paying off unsecured debt with your house as collateral puts the house at risk if the new payment becomes hard to keep.
Here is how the main options stack up.
| Option | What happens to your current loan | Equity limit |
|---|---|---|
| Keep it, borrow nothing | Stays in place | None |
| HELOC or home equity loan | Stays in place; new loan sits behind it | Set by that lender |
| FHA cash-out | Paid off and replaced | 80% LTV |
| Conventional cash-out | Paid off and replaced | Set by that program |
| FHA Streamline | Replaced; no cash out | No appraisal needed |
A loan that sits behind your first mortgage leaves the low rate alone. The trade-off is that it is a separate loan with its own terms, and it can carry its own costs. Whether that beats a cash-out is a matter of comparing the full terms on each Loan Estimate.
What Does Your Monthly Budget Look Like Afterward?
You cannot judge this from the cash amount alone. Here is what changes.
- A bigger balance. The new loan includes your old payoff, your cash, financed costs, and the upfront premium.
- A reset schedule. If you were ten years into your loan, you start over on a new term. You may pay interest for longer overall.
- Mortgage insurance. The monthly premium is new if you did not have it before.
- One payment. If you had a first mortgage plus a second loan, they merge into one.
- Closing costs. These are based on the whole new loan amount, not just the cash you take.
The right test is total cost, not just the monthly payment. Ask for the Loan Estimate and compare it against what you pay today.

Is This Right for You? A Quick Checklist
Answer these before you apply.
- Do you live in one unit and have you for at least 12 months?
- Has your payment history on the current mortgage been clean?
- Will 80% of the appraised value, minus all liens, leave enough cash for your goal?
- Have you compared the full terms of the cash-out against a loan that leaves your first mortgage alone?
- Can your budget carry a larger balance, a reset term, and mortgage insurance?
- Is the reason for the cash worth giving up your current terms?
If you can answer yes to the first four and the last two are close calls, run both sets of numbers side by side before you decide.

Frequently Asked Questions
Do I need an existing FHA loan to get an FHA cash-out?
No. The mortgage you are paying off can be conventional or FHA. The new loan is what carries the FHA insurance. You still need to meet the 12-month ownership and occupancy test and the other qualification checks.
Can I do an FHA cash-out on a duplex I rent out entirely?
Not with the standard program. FHA cash-out is for your principal residence, so you must live in one of the units. If you have moved out and rent both, occupancy rules decide what leverage and programs are open, and an owner-occupied FHA cash-out is not one of them.
Will a HELOC I already have reduce my cash-out?
Yes. A second lien that stays on the property counts toward the 80% combined cap. In the example above, a line equal to 10% of the home’s value cut the available room by that same 10%. If the line is paid off at closing, it no longer counts, but then the payoff comes out of your cash.
Does the rent from my other unit help me qualify?
Yes, it can. The lender typically counts only a portion of it, based on the appraiser’s market rent and your lease or rental records. It supports your file but does not replace your own income and credit.
Is a cash-out the same as a second mortgage?
No. A cash-out is one new first mortgage that replaces the old one. A second mortgage, like a home equity loan, is added behind your first mortgage and leaves it in place.
