The Quick Read: A conventional cash-out refinance on a two-unit home caps the new loan at 75% of the appraised value. A one-unit home gets 80%. The cap is not your cash. Your existing mortgage payoff, any other liens, and the closing costs come out of the cap first, and what is left is what you receive.
A duplex that appraises at $400K and has little debt against it produces a large check. The same duplex with a big first mortgage produces a small one, or none. Everything below shows how to work out your own number.
Cash-out refinance estimate
The starting figures are an example value with a balance and a cash request in proportion. Replace them with yours.
Editable benchmark: 7.18% as of November 5, 2026 · Freddie Mac 30-year average via FRED®. A conventional market reference, not a cash-out refinance quote.
Illustrative starting assumptions: a $350,000 home value, a $193,000 current balance, the agency cap on a one-unit principal residence, 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 rate field carries the weekly Freddie Mac thirty-year conventional benchmark, a market reference and not a cash-out refinance quote; a cash-out loan is priced by the lender at lock. The cash available is the loan the program cap allows less the balances paid off, before closing costs, which are not included. The HELOC line is the program’s combined loan-to-value ceiling applied to the same value and balance. Taxes and insurance are editable estimates. Licensed in sixteen states for consumer mortgages.
What a Cash-Out Refinance Does on a Duplex
A cash-out refinance replaces your current mortgage with a new, larger one. The new loan pays off the old one, then hands you the difference in cash. It is not a second loan on top of the first. It is one new loan, so your whole mortgage is reset.
The usual comparison is a refinance. That one changes the interest rate or the length of the loan and brings only a sliver of cash back. On a rate-and-term refinance, the cash back is limited and incidental by design. Cash-out is the version built to turn equity into money.
A duplex adds one wrinkle. Two-to-four-unit homes sit lower on the leverage chart than single-family homes. The lender worries a bit more about a building with more moving parts, so it lends a smaller share of the value.
You can see the programs side by side on Lendmire’s cash-out refinance programs page. Every figure here is subject to lender guidelines and a full file review, and none of it is a commitment to lend.
The Formula: Value × Cap, Minus Everything Owed
The cash-out formula is simple. Multiply the appraised value by the cap. Subtract what you owe. Subtract the closing costs. The remainder is your cash.
Three details trip people up:
- Appraised value, not purchase price. The appraiser sets the value. What you paid, and what you think the duplex is worth, do not.
- All liens count. If you have a second mortgage or a home equity line, it counts against the cap alongside the first loan.
- Costs come out of the same pool. If you roll closing costs into the new loan, the loan grows and your net cash shrinks.
On a duplex, the conventional program the network uses sets the cap at 75% of value. On a one-unit primary home, the same program sets it at 80%. Occupancy matters here, because it sets the leverage. The 75% figure covers two-to-four-unit homes whether you live in one unit, use it as a second home, or rent both. This article assumes you live in one of the units. If you rent out both sides, your lender will treat the file differently, and that is a conversation to have before you apply.
The Fannie Mae Eligibility Matrix is the agency’s own chart. It sets maximum leverage by transaction type, occupancy and unit count. It lists cash-out and limited cash-out separately.
The Master Table: What Comes Back at Different Balances
Take a duplex that appraises right at $400K. The table below expresses everything as a percentage of that appraised value, so you can scale it to your own number. It uses the 75% cap.
| Existing debt (% of value) | Max new loan | Gross cash before costs |
|---|---|---|
| 0% (paid off) | 75% | 75% |
| 25% | 75% | 50% |
| 50% | 75% | 25% |
| 60% | 75% | 15% |
| 70% | 75% | 5% |
| 75% or more | 75% | — |
“Gross” means before closing costs. Costs generally run a few percent of the loan amount, so the check you actually receive is smaller than the gross column. At 70% existing debt, a few percent of costs can wipe out the entire 5% of gross cash.
That last row is the break-even. Once your debt reaches the cap, the formula leaves nothing to give you. A duplex bought recently with a small down payment may sit close to that row.
What Closing Costs Do to Your Check
Closing costs cut your net cash in two ways. If you pay them at the table, you bring money to closing. If you roll them into the loan, your balance goes up, and so does what you owe back.
CFPB research notes that cash-out proceeds are often used to cover closing costs. It lists origination, appraisal and title fees among them. It also warns that tapping equity can carry substantial costs.
You will see the financed amount on your paperwork. The CFPB’s guide to the Loan Estimate and Closing Disclosure explains the “Closing Costs Financed” line.
Cash-out loans on the agency path also carry a pricing adjustment. Freddie Mac’s cash-out page says a credit fee tied to your score and leverage applies, with an exception for special-purpose cash-out loans. Brokers see this as a cost of the loan structure, so it belongs in your comparison. It does not appear as a separate line you can negotiate.
When the Appraisal Comes In Low
The appraisal moves your cash by more than you expect. The cap is a percentage of value, but your payoff does not change. A small miss on value becomes a larger miss on cash.
Here is the same duplex expected at 100% of $400K, with existing debt at 50% of that value.
| Appraised value | Max new loan | Gross cash before costs |
|---|---|---|
| 95% of expected | 71.25% | 21.25% |
| 100% of expected | 75% | 25% |
| 105% of expected | 78.75% | 28.75% |
A 5% miss on the appraisal cuts the gross cash from 25% of the expected value to 21.25%, a drop of 15% of the cash you hoped to receive. On a duplex, the appraiser also looks at what each unit would rent for and compares the building to similar two-unit homes. Fewer true duplex sales nearby can make the value harder to pin down.
Who Qualifies: The Gates Before the Math
The cap only matters if you clear the gates in front of it. Across the wholesale conventional programs we place files with, these are the main ones.
Seasoning. Seasoning is the waiting period a lender wants before you can cash out. The mortgage you are paying off must be at least 12 months old, counted from note date to note date. You must have been on title for at least 6 months. Delayed financing, inheritance and legal-award exceptions exist, and a cash buyer who refinances soon after purchase may fit the delayed-financing exception.
This is where the word “first” in a first duplex bites. If you bought it recently, the clock may not have run out. The guidelines vary a little by lender, so check your note date before you spend time on numbers.
Credit and ratios. The wholesale conventional programs start at a 620 decision score. The automated finding governs most files, with a total ratio ceiling of 50%. Manually underwritten loans run tighter, at 36% or 45%. A “ratio” here means your total monthly debts divided by your monthly income, including the new payment.
Credit events carry waiting periods set by the agencies. These are four years from a Chapter 7 discharge, seven from a foreclosure, and four from a short sale or deed in lieu. They can be shorter with documented extenuating circumstances.
Rental income from the second unit. Whether the rent from the unit you don’t live in counts as income is a lender and program question. It is not a given. Some lenders count part of it, some count it under conditions, and some don’t. Ask before you assume it helps your ratio. That shapes how much new payment you can carry.
Structures and Variations
A duplex cash-out is not the only path. The version you pick sets your cap and your cash.
Limited cash-out refinance. This is the rate-and-term lane. It carries a higher leverage allowance than cash-out and pays only incidental cash. Fannie Mae allows the lesser of 2% of the new loan or $2,000. Freddie Mac allows the greater of 1% of the new loan or $2,000. The Fannie Mae matrix lists limited cash-out separately from cash-out.
FHA Streamline and VA IRRRL. These are no-cash-out products for people who already hold an FHA or VA loan. An FDIC summary of the FHA Streamline says no cash may be taken out, no new appraisal is required, and borrowers must meet payment-history and seasoning tests. VA lists the IRRRL as a separate product, and a new Certificate of Eligibility is not required. If your goal is cash, neither is the tool.
VA cash-out. If you hold a Certificate of Eligibility and live in the home, VA’s cash-out loan page says you can take equity out. It also says you can refinance a non-VA loan into a VA loan. The lender orders the appraisal, and the loan goes through a private lender, not through VA directly. The leverage on a VA cash-out differs from the conventional chart, and lenders set their own limits within the program.
FHA cash-out. Standard FHA cash-out is for owner-occupied principal residences. A non-occupant co-borrower’s income cannot be used to qualify.
Where the General Rule Breaks
The 75% figure is a good starting point. It is not universal. These named edge cases move the answer.
- No existing mortgage. A duplex you own free and clear still counts as a cash-out when you borrow against it. The cap applies the same way, and the table’s top row shows the result.
- Delayed financing. A cash purchase followed by a refinance can sidestep the six-month title wait. It is a named exception to the seasoning rule.
- A co-owner buyout. Buying out a co-owner under a written agreement is treated as a limited cash-out transaction at both Fannie Mae and Freddie Mac. Your cap and your cash-back limits follow the limited cash-out rules, not the cash-out rules.
- State rules. Some states add their own limits. In Texas, a cash-out on a homestead is capped at 80% of the home’s value by the state constitution. On a duplex, the 75% agency cap is the tighter limit. Other states have their own homestead rules, so state law can add limits beyond the agency chart.
- Appraisal surprises. A low value cuts the cap, and a high one raises it. See the table above.
- Rental use. If you rent both units, occupancy changes the file. The leverage is set by occupancy, so confirm the product with your loan officer before you apply.
What Your Decision Looks Like in Practice
Picture a homeowner who bought a duplex, lived in one unit, and rented the other. Two years later the building has gained value and the mortgage has dropped. Run through four questions.
What will the appraisal likely say? Look at recent two-unit sales near you, not single-family sales. That tells you whether your value assumption is realistic.
What do I owe in total? Add the first mortgage, any second lien and any line of credit. Divide by your expected value. If the result is near 75%, there is little or no cash to find.
What will the new payment do to my budget? A larger balance generally means a larger payment, even when the interest rate drops. The CFPB’s Should I refinance? Handout points out that a lower payment can come from a longer term, not a better deal. Your Loan Estimate shows the total cost and any prepayment penalty. Compare those lines, not just the monthly figure.
What is the cash for? Cash that pays down higher-cost debt or funds a repair can make sense. Cash that disappears into everyday spending usually doesn’t. The CFPB’s home equity guide is blunt: a cash-out loan is debt you must repay, with your home as collateral and a risk of foreclosure if you can’t pay. It suggests comparing options with lower up-front costs, such as a home equity line, and it points to HUD-approved housing counseling before you borrow.
Here’s a genuine toss-up. A home equity line of credit often has lower up-front costs and leaves your first mortgage alone. A cash-out resets everything but can give you more cash in one move. Which one wins depends on what you owe now and how long you plan to stay.
Key Terms Defined
Cash-out refinance: A new mortgage that pays off your old one and gives you the leftover equity in cash.
LTV (loan-to-value): The new loan balance divided by the appraised value. A 75% LTV means the loan is three-quarters of the home’s value. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
Seasoning: The waiting period a lender requires before you can cash out, counted from your loan date or the date you took title.
Limited cash-out: A refinance that pays off the existing loan and costs, with only a small amount of cash back.
Appraised value: The figure a licensed appraiser assigns to the home. It sets your cap, not your purchase price.
Lien: A legal claim against the property for a debt, such as a first mortgage or a second loan.
Frequently Asked Questions
How much cash will I get on a $400K duplex?
It depends on your existing debt. The new loan can reach 75% of the appraised value on the conventional program. Subtract your payoff, any other liens and the closing costs. If you owe about half the value, roughly a quarter of the value is the gross figure before costs. If you owe 75% or more, nothing is left.
Why does a duplex get less than a single-family home?
Two-to-four-unit homes carry a lower cash-out cap, 75% against 80% for a one-unit primary home. The lender sees more risk in a building with more units. Occupancy also sets the leverage, so the cap follows how the property is used.
Do I need to wait before I can cash out?
Usually, yes. The first mortgage being paid off must be at least 12 months old, and you need to have been on title for 6 months. Delayed financing, inheritance and legal-award exceptions exist. A recent purchase may not clear the clock.
Can I use the rent from the other unit to qualify?
Sometimes. Whether that rent counts as income depends on the lender and program. Ask early, since it changes how much new payment your ratio can carry.
Is a cash-out the same as an FHA Streamline or VA IRRRL?
No. Those are no-cash-out products for existing FHA or VA loans. They lower costs on the loan you have. They are not a way to reach equity.
Next Step
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.
A first duplex is still one property with one appraised value, and the cap applies to the whole building. The closer your debt sits to 75% of value, the less there is to take.
