House Hacking in Dallas: FHA Duplex Loans and Limits in 2026

Can You Buy a Duplex in Dallas With an FHA Loan?

Yes. FHA loans allow you to buy a property with up to four units as long as you live in one of them. In Dallas and the DFW suburbs, the 2026 FHA loan limit for a two-unit property is $721,400, which covers a wide range of duplexes in Garland, Mesquite, Irving, and other markets where multifamily inventory is still active. You can bring as little as 3.5% down with a 580 credit score, and HUD lets you count 75% of the projected rental income from the other unit toward your qualification.

Buyers who want to build wealth through real estate usually see the down payment on an investment property as the biggest hurdle. With an FHA multifamily loan, that hurdle is smaller than most people expect, and the rental income from your tenant helps offset what you owe every month.

It is not a loophole. It is exactly what the program was designed for.

How FHA Multifamily Loans Work in Dallas

FHA insures loans on properties with one to four units. The rules are the same across all unit counts with one critical requirement: you must live in one of the units as your primary residence. That owner-occupancy requirement is what makes the program available to buyers rather than pure investors, and it is non-negotiable for at least the first twelve months.

The 2026 FHA loan limits for Dallas County, Collin County, Denton County, and Tarrant County are set by HUD based on area median home prices:

Down payment is 3.5% with a 580 or higher credit score. On a duplex at the limit, that is about $25,250. If your score falls between 500 and 579, FHA requires 10% down instead.

FHA also charges mortgage insurance. You pay 1.75% of the loan amount upfront at closing, and an annual premium that typically runs around 0.55% of the remaining balance on 30-year loans above 90% LTV. On a loan near the duplex limit, that upfront premium adds roughly $12,000 to your costs, which most buyers roll into the loan rather than pay in cash.

The Rental Income Rule

This is where FHA multifamily lending gets interesting.

HUD allows lenders to count 75% of the projected rental income from the units you will not occupy. That income goes toward your qualifying income, which means a duplex where the other unit rents for $1,800 per month adds $1,350 per month to your qualifying power. For buyers who are stretched on a single-family home purchase, that offset can be the difference between qualifying and not.

For three- and four-unit properties, FHA applies a self-sufficiency test. The total rental income from all units except yours must cover the full monthly PITI payment, including the FHA mortgage insurance premium. If the rents do not pass that test, you either need a larger down payment or a less expensive property. Two-unit properties are not subject to this test, which is one reason duplexes are the most common house-hack purchase in DFW.

Lenders calculate projected rental income using an appraisal and HUD Fair Market Rents for the Dallas-Plano-Irving metro. The appraiser provides a market rent estimate, and the lender uses the lower of that estimate or 75% of actual signed leases if a tenant is already in place.

One thing buyers often overlook: if you plan to buy down your interest rate to lower the monthly payment, that buydown affects your PITI but not the self-sufficiency calculation on three- and four-unit properties. The test uses the full market rate payment. Plan accordingly.

Running the Numbers on a Dallas Duplex

Here is how this plays out on a real purchase.

Say you find a duplex in Garland or Mesquite priced at $650,000. At 3.5% down, you bring $22,750 to closing. Your loan is $627,250, well under the $721,400 limit for Dallas County.

The other unit rents for $1,700 per month. Your lender counts $1,275 of that toward your qualifying income. That reduces the effective cost of carrying the loan each month, which is why buyers who could not qualify for a single-family home in the same price range can sometimes qualify for a duplex.

Your monthly costs will include principal and interest, the FHA mortgage insurance premium, property taxes, and insurance. Property taxes in Dallas County run roughly 2% to 2.5% of appraised value annually, so budget around $1,000 to $1,350 per month on a $650,000 property. Texas has no state income tax and no real estate transfer tax, which helps on the seller side, but property taxes are a meaningful line item in a house-hack analysis.

If you are weighing fixed versus adjustable rate options for this kind of purchase, most buyers opt for a fixed 30-year on the FHA loan. Adjustable rates introduce payment variability that complicates the house-hack math when you are counting on a predictable rental offset each month.

After the first year of owner-occupancy, you are free to move out and rent both units. Some buyers repeat the process, using the equity and rental history from the first property to help qualify for a second. That is the core of the house-hacking strategy: your first duplex pays you back while you live in it, and it becomes a full rental when you move on.

Frequently Asked Questions

Does FHA require you to live in the property after buying it?

Yes, for at least one year. FHA owner-occupancy rules require you to establish the property as your primary residence within 60 days of closing and live there for at least 12 months. After that period, you are free to move out and rent all of the units, and there is no requirement to refinance out of FHA at that point.

Can you use FHA on a triplex or fourplex in Dallas?

Yes, up to four units. The 2026 FHA limit for a three-unit property in Dallas County is $872,000, and for four units it is $1,083,650. The self-sufficiency test applies to both, meaning the combined rent from all units except yours must cover the total monthly payment. Triplexes and fourplexes are harder to underwrite but can generate significantly more rental offset than a duplex.

What credit score do you need for an FHA duplex loan in DFW?

580 for 3.5% down. Between 500 and 579, FHA requires 10% down. Most lenders in DFW also set their own overlays, often requiring a 620 minimum, so your credit score affects both your program eligibility and which lenders will work with you. Improving your score before applying is usually worth a few months of delay.

How long do I need to live in the property before I can rent out my unit?

The FHA standard is 12 months, beginning within 60 days of closing. There is no requirement that you stay after the first year. Many buyers use the first year to stabilize the property, establish a rental history with the other unit, and then move into a new purchase while keeping the duplex as a full rental.

Do I need a real estate agent who understands FHA multifamily in Dallas?

It makes a meaningful difference. FHA appraisals on multifamily properties are more involved than single-family, and the rental income documentation your lender requires adds complexity to the offer terms and inspection process. An agent who has closed FHA multifamily transactions in DFW can help you navigate the appraisal process, negotiate seller concessions that reduce your out-of-pocket costs at closing, and structure the contract to protect your option period rights under Texas law.
