The Quick Read: Two separate tests cap a conventional cash-out refinance on a duplex, triplex or fourplex you live in. The new loan must stay under the county loan-size ceiling, and it must stay at or below 75% of the appraised value. Whichever test is tighter sets your maximum. On a one-unit home the value cap is 80%, so a 2-4 unit starts with five fewer points of equity to borrow against, subject to lender guidelines and full file review.
Key Takeaways
- The value cap on a 2-4 unit principal residence is 75%. A one-unit home gets 80%.
- Any second lien that stays in place, such as a HELOC, counts toward that 75%.
- The loan you are paying off must be at least 12 months old, and one borrower must have been on title for 6 months. There are exceptions.
- Rent from the other units can help you qualify, but lenders discount it, and the full housing payment still counts against you.
- Cash-out is a loan purpose of its own, with its own pricing and timing tests. It is not a rate-and-term refinance with a bigger balance.
What Counts as a 2-4 Unit Home?
A 2-4 unit home is a duplex, triplex or fourplex. Conventional loans treat one to four units as residential. Five or more units move into commercial lending, which runs on different rules.
For this article, you live in one of the units. That is the owner-occupied case, often called a house hack.
If you own a rental or second home and the question is how much leverage it gets, the answer is short. In the programs Lendmire arranges, occupancy decides the leverage, and the cash-out cap on two to four units is 75% for a principal residence and for an investment property. A second home is not a 2-4 unit product in these programs. The rest of this article stays with the home you live in.
The Two Limits, Explained
Think of the two limits as two doors. Your loan has to fit through both.
The leverage cap is a percentage of the appraised value. Lenders compare your total debt to the value of the property. On a conventional cash-out refinance of a two- to four-unit principal residence, that ceiling is 75%. A one-unit principal residence gets 80%. Brokers in this space call it loan-to-value, or LTV. The agency matrix measures it a bit more broadly, as combined loan-to-value, which adds in any second mortgage or HELOC that stays on the property. The Fannie Mae Eligibility Matrix lists 75% for two to four units and 80% for one unit. Freddie Mac’s Guide, section 4203.1 shows the same 75% for a 2- to 4-unit primary residence.
The loan-size ceiling is a dollar limit. It is set by county, and a federal regulator publishes it each year. A conventional loan above the limit is a jumbo loan and moves into a different set of programs. The Federal Housing Finance Agency publishes the numbers in its annual conforming loan limit announcement. Limits for two to four units run higher than for one unit. In high-cost counties, the agency builds them from the local median home value and a multiplier for each unit count. Look up your county on the FHFA’s list instead of trusting a number from a blog post. The limits change on a yearly cycle, and the next set normally comes out in the late fall.
The two limits measure different things. One is a percentage of value. The other is a fixed dollar line for the county. Most guides blur them together.
Which Limit Controls?
The tighter one wins. That is the whole rule.
In most counties, the 75% test binds first. The loan-size ceiling sits well above what a typical duplex or triplex supports at 75% of value. In a high-cost county with a pricey fourplex, it can flip. The dollar ceiling stops the loan before 75% of value does. You would then have equity left over that you cannot reach with a conventional loan.
A quick way to check is to take 75% of your expected appraised value. Then compare it to your county’s limit for your unit count. If the first number is higher, the county ceiling is your real cap. If it is lower, the 75% test is.
A Worked Example
These numbers are modeled assumptions, not market data. Say a triplex appraises at 100% of value. You live in one unit and rent the other two.
- The maximum total debt is 75% of value.
- Your current first mortgage is at 55% of value.
- A HELOC you plan to keep is at 5% of value.
- Room under the cap is 75% minus 60%, or 15% of value.
That 15% is not your cash. Closing costs, prepaids and escrow deposits come out of it. If the new loan also pays off the HELOC, the first mortgage and the second lien both leave the picture, and the cap applies to one new loan. Pay the HELOC off at closing and your room under the cap grows by those five points of value. Leave it in place and it eats into the same 75%.
Now run the same property as a one-unit home. The cap is 80%, so the room is five points larger. That gap is the cost of the extra units.
One more wrinkle: the appraised value is the denominator. A new appraisal is part of this loan. If the appraiser comes in lower than you expected, every number above moves with it.
How the Loan Is Underwritten, Step by Step
Here is how a cash-out file on a 2-4 unit moves through the wholesale programs Lendmire works with. Each step can stop the file.
1. Classify the loan purpose. Cash-out means the proceeds have no restrictions on use. A property with no mortgage at all is also treated as cash-out when you refinance it.
2. Check the timing tests. The loan being paid off must be at least 12 months old, counted from note date to note date. At least one borrower must have been on title for at least 6 months before the new loan is disbursed. Both are measured to closing, not to your application date.
3. Check occupancy. For an owner-occupied cash-out, the borrowers must live in the property. Move out and the loan shifts into a different category with different limits.
4. Order the appraisal. Expect a new appraisal and inspection. On 2-4 units, the appraiser also reports market rents for the other units, which feeds the income calculation.
5. Run the ceiling. The lender takes 75% of value, subtracts second liens that stay, and sets the maximum new first loan.
6. Underwrite the income. Your personal income counts. So can a share of the rent from the units you do not occupy, if it is documented.
7. Price the loan. Cash-out loans carry pricing adjustments that grow with LTV and drop with stronger credit. Your broker quotes this live, and it appears on your Loan Estimate.
How Rent From the Other Units Counts
Rent helps, but it is discounted. A lender does not credit the full rent. Leases, traditional personal-income documentation and the appraiser’s rent schedule are the usual proof. The full housing payment still counts as a debt on your side.
The reason is simple. Tenants leave, units sit empty, and roofs leak. A lender will not pretend your rental income arrives every month at 100%.
Credit and Ratios
The wholesale conventional programs generally start at a 620 decision score. The automated underwriting finding governs most files, with a total debt-to-income ceiling of 50%. Manually underwritten loans run at 36% or 45%, depending on score and reserves. Reserves are cash left after closing. They matter more when your ratio is high or when you are carrying several units.
Mortgage insurance is required above 80% LTV. A 2-4 unit cash-out tops out at 75%, so it normally does not apply here. That is one small mercy of the lower cap.
The Tests at a Glance
| Test | What it checks | Common exception |
|---|---|---|
| Loan age | Loan being paid off is 12+ months old | Second liens, co-owner buyouts |
| Title time | A borrower on title for 6+ months | Inheritance, legal award, delayed financing |
| Occupancy | Borrowers live in the property | None for owner-occupied |
| Value cap | Total debt at or below 75% of value | None |
| Loan size | New loan under the county ceiling | Jumbo programs above it |
The Fannie Mae Selling Guide, section B2-1.3-03 sets the seasoning rules and lists the exceptions. Borrowers confuse the two clocks all the time. The 12-month clock is about the age of the loan. The 6-month clock is about how long you have owned the home. A nine-month-old loan fails the first test even if you have owned the building for years.
Where the General Rule Breaks
The 75% cap is a rule with edges. These are the ones that come up most.
- Delayed financing. Bought the building with cash? If you purchased within the last six months, you may be able to refinance and pull out your purchase cash, when the delayed-financing conditions are met. A cash buyer has no first mortgage, so the 12-month loan-age test does not come into play.
- Inheritance or a legal award. There is no ownership waiting period if you acquired the property by inheritance, or were awarded it in a divorce, separation or dissolution of a domestic partnership.
- Paying off a second lien. The 12-month test does not apply to a subordinate lien you pay off. A co-owner buyout under a legal agreement is also exempt.
- Revocable trust. Time held in a revocable living trust can count toward the six months, when you are the primary beneficiary.
- Property listed for sale. It must come off the market on or before the date the new loan is disbursed.
- Ineligible structures. Loans with a temporary buydown, loans that pay off an installment land contract, and certain properties with a PACE lien are not eligible for conventional cash-out. PACE is a type of energy-improvement assessment that sits on the property.
- Student loan payoff. The agency waives its cash-out pricing adjustment when proceeds pay off eligible student loans. Ask your broker whether the file qualifies.
- Affordable-housing programs. Income-limited programs like HomeReady and Home Possible are built mainly for purchases and limited-cash-out refinances. Check the current guide for the product you have in mind before assuming cash-out is on the menu.
- Texas. A cash-out on a Texas homestead also has to follow the state constitution’s own homestead rules, which sit on top of the agency limits. Lendmire’s wholesale 89.99% no-mortgage-insurance lane is not written there. Ask your broker what applies to your file.
Wholesale programs vary at the edges. A lender can set a stricter floor than the agency does. That is why a file that fits the agency rule on paper can still hit a lender overlay.
What Pulls Your Cash Below the Cap
The cap is a ceiling, not a payout. Your net cash is the new loan minus several things:
- The payoff of your existing first mortgage.
- Any second lien paid at closing.
- Closing costs and prepaids, such as taxes and insurance collected in advance.
- Escrow deposits set up at closing.
The costs can be rolled into the loan if you choose. That raises your balance and uses up some of your 75% room. So the amount that lands in your account is smaller than the cap suggests.
Appraisal risk is the other leak. A value that comes in lower shrinks the cap on the same day.
Cash-Out, Rate-and-Term, HELOC: How to Decide
Here is the decision as it usually plays out in practice.
| Option | Best when | Trade-off |
|---|---|---|
| Cash-out refinance | You need a large sum and want one loan | Value cap of 75%, new appraisal |
| Rate-and-term refinance | You want a new loan or term, with only incidental cash | Much higher leverage allowed, little cash |
| HELOC or second loan | You like your current first mortgage | Counts toward the same cap |
A rate-and-term refinance replaces your first mortgage and pays closing costs, with little cash back. It allows much more leverage than cash-out does, because the lender is not putting new money in your hands. The Lendmire cash-out refinance programs page lays out the choices in more detail.
A second loan on top of a first mortgage you want to keep can make sense. But the combined balance still has to fit under the same 75%. If your current loan carries a payment structure you value, keep it in mind. Cash-out replaces the old loan on new terms and a larger balance.
Weighing the Risk
A cash-out loan swaps equity for debt. The Consumer Financial Protection Bureau points out that a cash-out refinance may stretch out the time it takes to pay off your mortgage. The monthly payment may rise because the new loan is larger. The same guide notes that none of the home-equity options lets you turn 100% of your equity into cash.
Using the money to pay off unsecured debt, like credit cards, turns that debt into debt secured by your home. If something goes wrong, the lender can foreclose. That is the trade. Think hard before you make it.
On a 2-4 unit, there is one more risk. Your qualifying income counts rent that tenants may not pay. Run your own budget on the days when one unit sits empty.
Tax treatment can depend on your situation; borrowers should speak with a qualified tax professional before relying on any deduction or credit.
Key Terms Defined
LTV (loan-to-value): Your loan balance divided by the appraised value of the property, shown as a percentage.
CLTV (combined loan-to-value): Total of all liens on the property, including a HELOC, divided by the appraised value.
Seasoning: The waiting period a lender wants before a loan or ownership counts for a refinance.
Cash-out refinance: A new mortgage that pays off your old one and gives you the leftover cash to use as you choose.
Note date: The date you sign the loan paperwork. Seasoning clocks are counted to it.
Reserves: Cash and liquid assets you still hold after closing.
Conforming loan limit: The county dollar ceiling for loans that Fannie Mae and Freddie Mac can buy.
How to Prepare, Step by Step
Start with the appraised value, because everything else hangs on it. Then list every lien on the property, including the HELOC you may have forgotten about. Check the dates on your current loan and your deed. If you are inside the 12-month or 6-month window, wait or ask about an exception.
Gather leases, two years of traditional personal-income documentation if you have rental income, and proof of the units you rent. Check your county’s loan-size ceiling on the FHFA site. Then ask a broker to run both tests side by side, so you see which one binds before you order an appraisal.
Frequently Asked Questions
How much can I borrow on a duplex with a conventional cash-out refinance?
Up to 75% of the appraised value, counting any second lien you keep, and no more than your county’s loan-size ceiling. Whichever number is lower is your cap. Lender guidelines and full file review decide the final figure.
Why is a duplex capped lower than a single-family home?
More units mean more reliance on tenant income, and lenders price that risk into leverage. The programs Lendmire arranges allow 80% on a one-unit principal residence and 75% on two to four units. It is a risk rule, not a penalty for having rental income.
Do I need to own the building for 12 months?
Not exactly. The loan you are paying off must be at least 12 months old. Separately, one borrower must have been on title for at least six months. Inheritance, a legal award and delayed financing have their own exceptions.
Does a HELOC count against my limit?
Yes. The 75% cap applies to total debt on the property, so a HELOC you keep reduces how much a new first loan can reach. Paying the HELOC off at closing frees that room.
Can I move out and keep the owner-occupied limit?
No. For an owner-occupied cash-out, the borrowers must occupy the property. If you move out, the loan is treated under different occupancy rules, and a different lender review applies.
