The Quick Read: The cap on a duplex cash-out refinance comes from the loan program, not from the appraisal and not from the lender’s mood. On a conventional loan where you live in one unit, the ceiling is 75% of the home’s appraised value, compared with 80% on a one-unit home. The appraisal sets the value that percentage is applied to, and an individual lender can set a lower limit than the program allows.
What Does the Loan-to-Value Cap Actually Measure?
Loan-to-value (LTV) is the new first mortgage divided by the appraised value of the home. A cap of 75% means the new loan cannot exceed three-quarters of what the appraiser says the property is worth. Whatever remains after that limit pays off your existing loan and closing costs. What is left is your cash.
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: 7.24% as of October 29, 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.
On a refinance, the sales price from a past purchase no longer matters. Only the appraised value counts. That is why two owners with the same purchase history can walk away with very different cash amounts after the appraisals come back.
Two related terms show up on lender worksheets. Combined LTV (CLTV) adds any second liens that stay in place. Home equity combined LTV (HCLTV) counts the full credit line on a home equity line of credit, drawn or not. Fannie Mae’s loan-level price adjustment matrix notes that the undrawn part of a HELOC is left out of CLTV for one specific pricing test. Eligibility tests may treat the line differently, so ask how your lender counts it.
Who Sets the Cap? Four Layers
No single party decides. The number you see is the result of four layers stacked on top of each other.
| Layer | What it controls | Where you see it |
|---|---|---|
| Loan program | Maximum LTV by purpose, occupancy, units | Published eligibility matrix |
| Investor or buyer of the loan | Which loans it will purchase | Wholesale lender guidelines |
| Lender overlay | Stricter limits than the program | Lender’s own matrix |
| Broker channel | Which lender fits your file | Program match at application |
The program layer is the floor of the rules. Fannie Mae publishes its leverage limits in its Eligibility Matrix, which states the cap by loan purpose, occupancy and number of units.
A lender can then add an overlay, meaning a stricter rule than the program minimum. That is why one quote might sit lower than another for the same house. A broker’s job is to know which wholesale lenders apply which overlays and to place the file where it fits. Across the wholesale programs Lendmire places files with, the common pattern is that the program cap is the ceiling and a few lenders trim below it for certain credit or property profiles.
How Does a Lender Decide Which Cap Applies?
The lender walks through the same sequence on every file. Each step narrows the answer.
1. Classify the transaction. A cash-out refinance is a loan whose proceeds exceed the payoff, closing costs and prepaid items. A home with no existing mortgage is also treated as cash-out.
2. Confirm occupancy. If you live in one unit of the duplex, it is a principal residence. That is the most favorable occupancy category.
3. Count the units. A duplex is a two-unit property and gets its own row in the matrix.
4. Apply the program limit. For conventional cash-out, that is 75% on a two- to four-unit principal residence, versus 80% on a one-unit principal residence.
5. Apply any overlay. The lender may lower the number for credit, property or documentation reasons.
6. Order the appraisal and test the loan. The new loan plus any liens that stay in place must fit under the cap times the appraised value.
7. Run the rest of underwriting. Credit score, debt-to-income ratio, reserves and seasoning still apply.
Once the cap is known, the loan has to pay off the existing mortgage and any liens being paid. Cash to you is what is left after payoff and costs. If you finance the closing costs into the loan, they use up some of the room under the cap.
Why Does a Duplex Get a Lower Cap Than a Single-Family Home?
Risk is the reason. A two-unit property is harder to value, it can be harder to resell quickly in a down market, and its performance depends partly on a second household. Agencies price that extra uncertainty into a lower maximum on cash-out loans.
The gap is meaningful. At the program level, a one-unit principal residence reaches 80% on cash-out, while a two- to four-unit principal residence stops at 75%. On a home worth the same amount, the duplex owner can borrow five percentage points less of the value, and that difference comes straight out of the cash available.
Here is the catch for buyers. Purchase loans are more generous. Two- to four-unit principal residences can reach 95% on a purchase. So a duplex that was easy to buy with a small down payment may feel tight when you try to pull equity out later. Cash-out is the most conservative transaction, and a duplex is the more conservative property type.
Owner-Occupied Duplex vs. Other Occupancy
Occupancy decides which row of the matrix applies. Living in one unit of the duplex keeps you in the principal-residence category, and renting out the other half does not change that. Rental income from the second unit can help you qualify, but it does not raise the cap.
| Occupancy | Conventional cash-out cap | Notes |
|---|---|---|
| One-unit principal residence | 80% | Highest cash-out leverage |
| Duplex, you live in one unit | 75% | Rent from other unit helps qualifying only |
| Second home or non-owner-occupied | 75% | Occupancy rules differ |
If you move out, the property is no longer your principal residence, and the loan must be underwritten under the occupancy you actually have. Lenders ask you to certify your intent to occupy. Misstating it is a serious problem, so the cleaner path is to refinance while you still live there, if cash-out is your goal.
Cash-Out vs. Limited Cash-Out: Why the Caps Differ
Many owners confuse the two. A limited cash-out refinance, also called rate-and-term, pays off your current mortgage, closing costs and a purchase-money second lien, with only incidental cash back. Because you are not taking equity out, the cap is higher. On a one-unit principal residence, a rate-and-term refinance can reach 95% LTV. Two- to four-unit homes get their own limits, and the Fannie Mae HomeReady matrix shows that 2-4 unit principal residences are eligible for HomeReady on purchase and limited cash-out transactions, not on cash-out. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
| Factor | Limited cash-out | Cash-out |
|---|---|---|
| Purpose | Lower balance cost, change term or rate | Take equity as cash |
| Cash back | Incidental only | Proceeds beyond payoff and costs |
| Leverage | Higher cap | Lower cap |
| Mortgage insurance | Required above 80% LTV | Not needed within the cash-out caps |
The pricing grids also differ. Fannie Mae’s loan-level price adjustments have separate tables for limited cash-out and cash-out, by credit score and LTV band, so cash-out generally costs more for the same score and leverage.
A Worked Example in Percentages
Take a duplex where you live in one unit and the appraisal comes back at 100% of what you expected. Under a 75% cap, the new loan can be no more than 75% of that value. Say your current mortgage is 50% of value and closing costs are 3% of the new loan balance. Roughly 25 points of value sit under the cap. After you pay off the old loan and the costs, cash to you lands around 22 points of value.
Now run the low-appraisal version. The appraisal comes in 5% below your expectation. The same 75% cap now applies to a smaller number, so the maximum loan shrinks. Your payoff balance did not change, so the entire reduction comes out of your cash. A modest appraisal miss can eat a large share of the proceeds. Cash-out is the loan type most sensitive to appraisal.
Add a second lien. If a HELOC stays in place, its balance counts toward combined leverage. Every point of value tied up in that lien is a point you cannot take as cash unless the lien is paid off in the refinance. In many files, folding the second lien into the new first mortgage makes the numbers cleaner.
The Seasoning Clocks That Can Block You Before Equity Matters
Equity alone does not qualify you. Across the wholesale programs we place files with, two clocks come up constantly. The first mortgage being paid off generally must be at least 12 months old, measured from note date to note date. A borrower must also have been on title for at least 6 months. Exceptions exist for delayed financing for cash buyers, inheritance and legal awards. Delayed financing limits the proceeds to your documented purchase costs rather than the current appraised value, and it still carries cash-out pricing and caps.
A wholesale lane also exists that reaches 89.99% LTV with no mortgage insurance. It requires a 680 score, a 50% ratio and a thirty-year fixed rate on a primary residence at a conforming balance, with its own six months of seasoning. It is a specific lane, and whether a duplex fits depends on the lender’s guidelines and full file review. In Texas, a cash-out on the homestead is capped by the state constitution at the agency figure, and that wholesale lane is not written there.
Other Programs Set Their Own Caps
Each program sets its own limit, and the figures differ by program, occupancy and unit count. FHA and VA also offer streamline refinances for existing loans, but those are no-cash-out products. If you hold an FHA or VA loan today, a streamline may fit a lower-payment goal, while a conventional cash-out fits an equity goal. They solve different problems.
Key Terms Defined
Loan-to-value (LTV): The new first mortgage divided by the appraised value of the home.
Combined LTV (CLTV): The total of the first mortgage and any remaining second liens divided by the appraised value.
Overlay: A lender rule that is stricter than the loan program’s minimum.
Seasoning: The required age of your existing loan or your time on title before you can refinance.
Limited cash-out refinance: A refinance that pays off the old loan and costs with only incidental cash back.
Principal residence: The home you occupy as your main address, including a duplex where you live in one unit.
Common Reasons Your Quoted Cap Differs
- Lender overlay. The lender sets a number below the program cap.
- Loan type. FHA, VA, conventional and jumbo each have their own limits.
- Appraisal. A lower value shrinks the dollar amount under the same percentage.
- Liens. Second liens that remain count against combined leverage.
- Occupancy or unit count. A misclassified property uses the wrong row of the matrix.
Credit score and debt-to-income ratio mostly affect eligibility and pricing, not the cap itself. A wholesale conventional program starts at a 620 decision score, and the automated finding governs most files with a total ratio ceiling of 50%.
What Should You Do Before You Apply?
Pull your current mortgage statement and note the origination date so you can check the 12-month clock. Confirm how long your name has been on title. Decide whether you truly need cash or only a better term, because the second goal allows much higher leverage. If you do need cash, compare the amount you want against 75% of a realistic value, not an optimistic one.

Frequently Asked Questions
What is the maximum LTV on a duplex cash-out refinance?
On a conventional loan where you live in one unit, the cap is 75% of appraised value. A one-unit principal residence reaches 80%. Individual lenders may set a lower limit, and every figure is subject to lender guidelines and full file review.
Does renting the second unit raise or lower my cap?
Neither. Living in one unit keeps the property a principal residence, so the occupancy row stays the same. Rent from the other unit can help with qualifying, but the cap is set by the program, not by your rental income.
Can I get a higher percentage with a rate-and-term refinance instead?
Yes, but you get no meaningful cash back. A rate-and-term refinance on a one-unit principal residence can reach 95% LTV. Two- to four-unit properties have their own limits, so the right number depends on program and unit count. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
Does a low appraisal change the cap?
It changes the dollar amount, not the percentage. The same cap applies to a smaller value, so the maximum loan drops and your cash shrinks, since the payoff and costs stay the same.
Do I have to wait before refinancing a duplex for cash?
Often, yes. The loan being paid off generally needs to be at least 12 months old, and a borrower must have been on title for 6 months. Delayed financing, inheritance and legal awards are exceptions with their own rules.
