Can You Get an FHA Loan on a Duplex? Limits, Occupancy, and Income

Yes, you can get an FHA loan on a duplex, as long as you live in one of the two units as your primary home. The program lets you buy with as little as 3.5 percent down, and in 2026 the loan limit for a two-unit property ranges from $693,050 in lower-cost counties up to $1,599,375 in the highest-cost markets.¹ You can rent out the second unit and count most of its projected rent toward your qualifying income.

2026 Loan Limits for Two-Unit Properties

FHA sets loan limits county by county and updates them each year. For 2026, the two-unit floor is $693,050 and the ceiling is $1,599,375.¹ Your county sits somewhere in that range based on local home prices. These figures are meaningfully higher than the single-family limits, which floor at $541,287 and cap at $1,249,125.

To find your county’s exact number, use HUD’s lookup tool at entp.hud.gov. Pick your state, county, and CY2026 as the limit year, and the tool returns the maximum FHA loan amount by property type.² If the duplex you want costs more than the two-unit limit for your area, you’ll need a conventional loan or a larger down payment to cover the gap.

The Owner-Occupancy Rule

FHA loans are for buying a home, not an investment property. At least one borrower has to move into one of the units within 60 days of closing and intend to live there for at least a year.³ You pick which unit is yours and rent out the other. After the first year you can move out and keep the FHA loan in place, converting both units to rentals if you choose.

This residency rule is the whole reason FHA duplex financing exists on such favorable terms. Conventional investment property loans usually demand 15 to 25 percent down. The tradeoff: you actually have to live there, and lenders verify that intent during underwriting.

What Happens If You Don’t Move In

Claiming you’ll occupy a duplex and never moving in is federal mortgage fraud under 18 U.S.C. § 1014, which carries penalties of up to $1,000,000 in fines and 30 years in prison.⁴ Criminal cases against individual borrowers are rare, but the civil side does the damage. If a lender discovers the fraud, it can accelerate the loan, making the entire balance due at once. If you can’t pay, foreclosure follows. Servicers use post-closing audits, property inspections, and mail-forwarding checks to confirm occupancy, and a foreclosure triggered by fraud stays on your credit report for seven years.

Credit, Down Payment, and DTI

Financial qualification for a duplex works the same as for a single-family FHA loan. A credit score of 580 or higher qualifies you for the minimum 3.5 percent down payment. Scores between 500 and 579 require 10 percent down. Lenders also review at least two years of employment history to confirm stable income.

Your debt-to-income ratio generally has to stay at or below 43 percent, counting the new mortgage payment against gross monthly income. Higher ratios can still get approved with compensating factors: a larger down payment, minimal payment shock compared to your current rent, documented cash reserves, or a track record of handling similar housing costs.⁵

One point worth flagging: FHA does not require cash reserves on one- or two-unit properties. The three-month reserve rule kicks in only at three- and four-unit buildings.⁶ Having reserves still strengthens your file, particularly with a higher DTI.

Counting Rental Income From the Second Unit

This is the piece that makes duplex buying work for a lot of borrowers. FHA lets you count 75 percent of the projected market rent from the unit you won’t occupy toward your qualifying income. The appraiser estimates fair market rent, and the lender applies a 25 percent haircut to account for vacancies and maintenance.⁶ The remaining 75 percent is added to your income for DTI purposes.

If the appraiser puts market rent at $1,600 a month, you get credit for $1,200 in monthly income. On a tight DTI, that boost can be the difference between approval and denial. You don’t need a signed lease or an existing tenant. The appraiser’s market rent estimate is enough.

Duplexes also skip FHA’s self-sufficiency test, which requires three- and four-unit properties to generate rent that covers the whole mortgage payment. That test doesn’t apply to two-unit buildings.⁶

Mortgage Insurance Costs

Every FHA loan carries mortgage insurance, and on a duplex it’s often the biggest ongoing cost surprise. You pay it twice: once upfront at closing, and again as an annual premium spread across monthly payments.

The upfront premium is 1.75 percent of the base loan amount.⁷ On a $650,000 loan, that’s $11,375. Most borrowers roll it into the loan balance rather than paying cash at closing, which means you pay interest on it over time.

The annual premium depends on your loan term, loan-to-value ratio, and whether your base loan amount is above or below $625,500. For a 30-year loan with a down payment of 3.5 percent (LTV above 95 percent), the annual rate is 0.85 percent when the base loan is at or below $625,500 and 1.05 percent when it’s above. With 5 to 10 percent down (LTV between 90 and 95 percent), the rates are 0.80 percent and 1.00 percent respectively.⁷

Because the 2026 duplex floor is $693,050, many duplex loans clear the $625,500 threshold and land in the higher tier. At 1.05 percent on a $670,000 loan, that’s roughly $586 a month in mortgage insurance alone.

If you put down less than 10 percent, annual MIP stays on the loan for its entire life. There is no automatic cancellation based on equity or payment history. With 10 percent or more down, MIP drops off after 11 years.⁷ Many duplex owners end up refinancing into a conventional loan once they’ve built 20 percent equity to shed the insurance entirely.

Property Condition Requirements

The FHA appraisal covers market value and physical condition. Each unit needs its own working kitchen (sink, running water, stove hookup), at least one bathroom, adequate heating, hot water, and sufficient electrical service. Each unit also needs a continuing supply of safe, potable water and proper sewage disposal.⁶ The appraiser also inspects the roof, foundation, and walls for significant damage.

For duplexes built before 1978, deteriorating lead-based paint (peeling, chipping, cracking) is flagged as a hazard that has to be addressed before closing.⁸ Intact paint is generally fine.

The FHA appraisal is not a home inspection. It checks for specific safety and habitability problems, not aging HVAC, minor plumbing wear, or roof issues that haven’t yet caused visible damage. The appraisal protects the lender. A separate home inspection protects you. Get both.

You Become a Landlord at Closing

The moment a tenant moves into the second unit, you’re a landlord with tax and fair housing obligations. Rental income has to be reported on Schedule E (Form 1040), and shared costs like mortgage interest, property taxes, and insurance are split between your unit and the rental unit, typically by square footage. Expenses tied only to the rental side are fully deductible against rental income, and you can depreciate the rental portion of the building over 27.5 years.⁹

On the fair housing side, the Fair Housing Act prohibits discrimination based on race, color, religion, sex, national origin, familial status, and disability. Owner-occupied buildings with four or fewer units qualify for a narrow exemption under 42 U.S.C. § 3603(b)(2), sometimes called the Mrs. Murphy exemption, but it’s conditioned on not using a real estate agent and not publishing discriminatory advertising, and state laws often eliminate it entirely.¹⁰ Treating every applicant consistently and documenting your screening criteria is the safest approach.

Applying and Closing

Start by finding an FHA-approved lender that regularly writes multi-unit loans. Not every lender does. You’ll complete the Uniform Residential Loan Application (Fannie Mae Form 1003) and hand over standard documentation: two years of federal tax returns with W-2s or 1099s, 30 days of pay stubs, two months of bank statements, and government-issued ID.¹¹ Bring any existing lease for the second unit, or a schedule of proposed rents if it’s vacant. Make sure the application shows two units and lists the projected rental income; missing that detail slows things down.

Once your file is in, the lender requests an FHA case number and an FHA-approved appraiser evaluates the property. Underwriting reviews your income, credit, assets, the property’s condition, and the projected rent. Any habitability or safety issues the appraiser flags have to be repaired before final approval. From application to closing usually runs 30 to 45 days, longer if repairs are needed.

After closing, the 60-day clock to move in starts running.³ Update your address with the postal service, your driver’s license, and voter registration. That paper trail matters if your servicer ever audits occupancy.
