The Quick Read: A conventional cash-out refinance on a duplex, triplex or fourplex you live in lets the new loan reach 75% of the appraised value. Your cash is what is left after that new loan pays off your old mortgage and covers closing costs. The cap applies to the whole loan, not to your equity. That is why the check is always smaller than the equity you feel you have.
Key Takeaways
- The cash-out cap on a 2-4 unit principal residence is 75% of appraised value. A one-unit home gets 80%.
- The formula is simple: value times 75%, minus your payoff, minus costs.
- Duplex, triplex and fourplex share the same cap. Unit count changes the appraisal, reserves and loan-size test, not the percentage.
- At 75%, conventional mortgage insurance does not apply, because it starts above 80%.
- The 95% figure you hear for buying a duplex does not apply to cash-out.
What “Releases” Means (and What It Does Not)
“Releases” means cash that lands in your hands. It does not mean equity. Equity is value minus what you owe. Cash released is a smaller number, because the lender will not let the new loan climb past a set share of value.
Here is the picture. You own a fourplex and live in one unit. The appraiser says it is worth 100 units of value. You owe 50 units. Your equity is 50. But the cap on a 2-4 unit principal residence is 75% of value, so the new loan can reach 75 at most. Pay off the 50 you owe, and 25 of room is left. Closing costs come out of that 25 if they are rolled into the loan.
So 50 of equity became, at most, 25 of cash. Most surprises in this loan trace back to that gap.
Lendmire, a mortgage broker, arranges these loans through wholesale lenders. Its cash-out refinance programs follow the agency caps below, and the numbers here come from that same set of guidelines. Every figure here is subject to lender guidelines and full file review. Nothing here is a commitment to lend.
Where Does the 75% Cap Come From?
The cap comes from the agency matrix that conventional loans follow. Fannie Mae’s Eligibility Matrix lists cash-out refinance at 80% for a one-unit home and 75% for two to four units. The cap is measured as LTV, meaning loan-to-value, the loan balance divided by appraised value. Any second loan or HELOC counts toward the same limit.
The wholesale programs Lendmire places files with use the 75% figure for two- to four-unit principal residences.
Occupancy changes the picture. A second home or investment property also sits at 75% on these programs, but the rules about who must live in the property are strict. All borrowers must occupy a primary residence. A “live in one unit” claim has to be true.
How the Loan Is Underwritten, Step by Step
Think of the file as a series of gates. Each one can shrink the check or stop the loan.
Step 1: The appraiser values the whole building
For a 2-4 unit home, the appraiser uses a small residential income report, Fannie Form 1025. It values the property as a whole and records the market rent for each unit. Value is the number everything else multiplies. A lower appraisal cuts your room.
Step 2: The lender sets the maximum loan
Maximum loan equals appraised value times 75%. In the indexed example, 100 of value supports a loan up to 75.
Step 3: The old mortgage gets paid first
The new loan pays off your existing first mortgage. Any HELOC or second lien on the property is paid off too. These payoffs are required, and they come out before you see a dollar.
Step 4: Costs come out next
Title fees, origination charges, the appraisal and prepaid items are all part of closing. If you roll them into the loan, they use up room under the cap. If you pay them from savings, your check is bigger but your out-of-pocket is higher. Your Loan Estimate shows the real numbers.
Step 5: Pricing adjustments add cost
Fannie Mae applies a loan-level price adjustment, called an LLPA, to certain cash-out refinances. It depends on LTV and credit score. A higher LTV and a lower score mean a higher cost. That cost either trims your net cash or shows up in your pricing. The Selling Guide’s cash-out section explains the adjustment applies on top of other price adjustments.
Step 6: Credit, ratios and reserves
Pricing and available terms vary by lender, borrower profile, property type, and full underwriting review. The automated finding governs most files, with a total debt-to-income ceiling of 50%. Manually underwritten loans run tighter, at 36% or 45%, with score and reserve factors from the Eligibility Matrix.
Reserves are the savings left over after closing. A one-unit principal residence file can have no reserve requirement. A 2-4 unit file generally does. That difference catches households whose wealth is mostly the building itself.
Step 7: Disclosures and the right to cancel
You receive a Loan Estimate and a Closing Disclosure. A refinance on your primary residence also carries a short right to cancel after signing. Cash-out funds generally are not released until that window passes, so the money does not arrive at the closing table.
Worked Example: Indexed Numbers, Not Dollars
These are modeled assumptions, not market data. Value is set to 100 units and the payoff to 50 units. Costs are left as a line item because your Loan Estimate holds the real figure.
| Scenario | Value | Cap | Max loan | Payoff | Room before costs |
|---|---|---|---|---|---|
| 2-4 unit, base case | 100 | 75% | 75 | 50 | 25 |
| 2-4 unit, low appraisal | 92 | 75% | 69 | 50 | 19 |
| One-unit, same value | 100 | 80% | 80 | 50 | 30 |
Final cash equals the room, minus whatever costs you finance.
Two lessons sit in that table. First, the one-unit home yields more cash from the same value and balance, because its cap is five points higher. Second, the appraisal dropped 8 units and the room fell 6. The check falls by less than the value drop, but it still falls.
Duplex, triplex or fourplex?
The cap is the same for all three. What differs is the appraisal, the rent the building earns, and how the file is reviewed. Larger buildings tend to have more rent in play, but that rent does not raise your loan amount. It matters only when the lender checks whether you can afford the payment.
Why mortgage insurance rarely shows up here
On the conventional programs, mortgage insurance is required above 80% LTV. A 2-4 unit cash-out is capped at 75%, so it normally stays under that line. That is one quiet benefit of the lower cap.
What Shrinks the Check
Four things cut the number between “available equity” and “cash in hand.”
- A low appraisal. Every point of value lost takes room away from the loan, and the loss compounds against the allowed loan-to-value.
- Financed costs. Costs rolled into the loan use room one for one.
- Junior liens. A HELOC or second mortgage must be paid off, and it comes out ahead of your cash.
- Pricing adjustments. The LLPA grows with a higher LTV and a lower score.
Run the subtraction in that order and you will land close to the real figure.
How Rental Income Fits In
Rent affects qualifying. It does not raise the maximum loan. Those are two separate tests.
On a 2-4 unit home you live in, rent from the unit you occupy cannot be used to qualify. Rent from the other units can help, but the lender nets it against the full housing payment on the building. Fannie’s Selling Guide rental income topics set the rules. If the rent minus that payment comes out negative, the shortfall is added to your monthly obligations.
Documentation depends on your history. With a rental track record, expect the appraisal’s rent schedule plus traditional personal-income documentation with Schedule E. Without history, expect the schedule plus current leases. Lenders also report the market rent to Fannie Mae on these loans, whether or not you use it to qualify.
One more rule is worth knowing. The rental income allowance for an accessory dwelling unit applies only to one-unit homes. It does nothing for a 2-4 unit cash-out.
Where the General Rule Breaks
The 75% cap is the rule. These cases bend it or block it.
Recently purchased homes. The mortgage being paid off must be at least 12 months old, measured note date to note date. At least one borrower must have been on title for 6 months. Bought the building last season? Cash-out is usually off the table. Fannie Mae’s Selling Guide states both tests.
Delayed financing. This exception waives the six-month title rule when you bought the property with cash. The purchase must be at arm’s length and documented by a settlement statement showing no mortgage was used. The proceeds are limited, and the details turn on the file.
Inheritance and legal awards. Both are exceptions to the seasoning rules on the programs Lendmire works with.
Listed for sale. If the property was on the market, it must be off before the loan disburses. Owners who “tested the market” get caught here.
Special programs. HomeReady has its own matrix row, and cash-out refinances are not permitted with Community Seconds.
Texas homestead. The state constitution caps a cash-out on a homestead at the agency figure, so the higher-leverage wholesale lane is not written there.
Five or more units. That is commercial territory. This article covers only two to four.
Is Loan Size a Limit Too?
The loan-size limit and the LTV cap are two separate tests. The lower one controls. The Federal Housing Finance Agency sets conforming loan limits each year, and the limits rise with unit count. In high-cost areas the multi-unit limits are higher still.
For most 2-4 unit cash-outs, the LTV cap binds first. The loan limit matters on high-value buildings. If yours is one, the jumbo programs take over above the conforming limit, with their own score and leverage rules. Check your county’s current figure rather than assuming.
Do You Need to Take Cash at All?
A cash-out is not the only way to refinance. Consider three paths.
| Path | What the new loan does | Cash back |
|---|---|---|
| Cash-out | Pays off the old loan plus costs, returns the rest | Yes, up to the 75% cap |
| Rate-and-term (limited cash-out) | Pays off the old loan and costs | Only incidental |
| Keep your loan | Nothing changes | None |
The agency matrix lists limited cash-out at a much higher cap than full cash-out. If you only want a different term or payment structure, that route keeps you from taking a larger balance than you need.
Cash-out replaces your whole first mortgage with a bigger one. A larger balance and a cash-out price adjustment generally push the payment up compared with a rate-and-term refinance. Ask yourself what the cash is for, and whether the larger balance is worth it. 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): the loan balance divided by the appraised value of the property.
Cash-out refinance: a new mortgage larger than your old one, with the extra paid to you at closing.
Limited cash-out (rate-and-term): a refinance that pays off the old loan and costs, with only incidental cash back.
Seasoning: the minimum time a loan or title must be in place before you can refinance.
LLPA: a loan-level price adjustment, an added cost tied to LTV and credit score on some loans.
Reserves: savings left after closing that show you can keep paying.
Form 1025: the appraisal report for two- to four-unit properties, with a rent schedule for each unit.
Frequently Asked Questions
Can I take 80% of my equity out?
No. The cap is on the whole new loan, not your equity. On a 2-4 unit principal residence the new loan can reach 75% of value, and your old mortgage comes out of that first. What remains is your cash, before costs.
Why is my check smaller than my equity?
Because the lender caps the total loan at 75% of value, leaving a 25% cushion. Your payoff, any HELOC and financed costs all sit inside that cap. A low appraisal shrinks the room further.
Can I do a cash-out soon after buying the building?
Usually not. The loan being paid off must be at least 12 months old, and a borrower must have been on title for 6 months. Delayed financing is the exception if you bought with cash and can document it.
Does rent from the other units raise how much I can borrow?
No. Rent affects whether you qualify, not the cap. Rent from the unit you live in does not count at all. Rent from other units is netted against the building’s full housing payment.
Do I need extra savings for a duplex, triplex or fourplex?
Generally yes. A 2-4 unit principal residence file carries a reserve requirement that a one-unit file does not. The amount depends on the program and the automated finding, so confirm it early.
