FHA Loan on a Duplex in Orlando: Limits and Rent Math

A duplex can be a way to buy a first home and start investing in the same purchase. You live in one unit, rent the other, and the tenant's rent helps with the payment. It is how Sergio got started, and FHA financing is one of the most common ways buyers do it. This article covers the limits, the rent math, and the catch.

What FHA allows

FHA insures mortgages on properties with one to four units, as long as you live in one of the units as your primary residence. The maximum loan depends on the county and the number of units. HUD set the 2026 limits in Mortgagee Letter 2025-23, with a national floor of $541,287 for a one-unit home and $693,050 for a two-unit home. Orange County is not a high-cost county, so lenders report that the Orlando area sits at those floors. Limits are set county by county, so confirm the current number for your target area with your lender or on HUD's announcement before you shop.

FHA also allows a down payment as low as 3.5 percent for qualifying borrowers, with credit score requirements set by the program and your lender. Because the loan is insured, FHA charges mortgage insurance. There is an upfront premium of 1.75 percent of the base loan amount and an annual premium paid monthly, with the annual rate depending on your loan term, loan amount, and down payment. HUD publishes the premium tables.

The rent math

For a duplex, a lender can generally count part of the projected rent from the unit you will not live in when it decides whether you qualify. The lender will want a lease or an appraiser's market rent estimate, and the exact treatment is the lender's call, so ask early.

Three- and four-unit properties add a self-sufficiency test from HUD's FHA handbook. Seventy-five percent of the appraiser's market rent for all units, including the one you will occupy, must at least cover the full monthly payment: principal, interest, taxes, insurance, and mortgage insurance. Duplexes are exempt from that test.

Here is an example with invented numbers. Say a fourplex has four units with a market rent of $1,600 each. Seventy-five percent of $6,400 is $4,800. If the total monthly payment is $4,500, the property passes. If it is $5,200, it fails.

Your own math matters as much as the lender's. Suppose, again with made-up numbers, that the full payment on a duplex is $3,600 a month and the other unit rents for $1,900. Your net housing cost would be $1,700 a month. That figure is before vacancy, repairs, and any insurance surprises, so keep a reserve for the months the unit sits empty.

The catch

• You have to live there. An FHA loan is for a primary residence, so it does not work for a pure investment purchase. Ask your lender how long you must occupy the property before you can move out and rent both units.
• The property must pass FHA standards. The appraiser checks safety, soundness, and condition, and an older duplex may need repairs before the loan can close.
• You become a landlord. That means tenant screening, maintenance, and following Florida's landlord and tenant law in Chapter 83 of the Florida Statutes.
• Insurance and taxes change the payment. Get an insurance quote and a property tax estimate before you write an offer, since both feed the payment the lender qualifies you on.

Where to start

Begin with a pre-approval from a lender who does FHA loans on two- to four-unit homes, then search with the loan limit in mind. Central Florida markets with more accessible entry prices and steady rental demand, such as Kissimmee, Saint Cloud, and Meadow Woods, are where many first-time investors look first. For the bigger picture, read the guide on turning your first home into your first investment and the multi-family financing page, or talk it through with Sergio.
