FHA vs Conventional Loan for Multifamily in Texas: Which Puts You in the Door for Less?

What You're Actually Choosing Between

Almost every first-time investor in Texas small multifamily hits the same wall: they find the deal, run the numbers, and then discover the down payment requirement is the thing that kills it. That's where the FHA 203(b) loan — the standard FHA purchase mortgage for 1-4 unit owner-occupied properties — enters the picture.

The core split is this: FHA is an entry program, conventional is a scaling program. FHA gets you in the door with 3.5% down if your credit score is 580 or above. On a $400,000 Houston duplex, that's $14,000 at closing instead of $60,000 at a standard 15% conventional down payment. For a buyer without a war chest of capital, that gap is the difference between owning a deal this year and waiting four more years to save up. The trade-off is that FHA requires you to live in one of the units — the owner-occupancy requirement — and carries mortgage insurance that doesn't go away on its own. Conventional financing asks for more cash upfront, demands a stronger credit profile, and doesn't require you to be a resident. It scales better once you're building a portfolio. Understanding which one fits your situation right now is the decision this page helps you make.

2026 FHA and Conforming Loan Limits in Texas

FHA sets maximum loan amounts by county and unit count. For 2026, the FHA loan limits in Austin (Travis County) are $731,700 for a duplex, $884,450 for a triplex, and $1,099,150 for a fourplex. Houston and Dallas sit at different county limits — buyers should verify their specific county before assuming the Austin figures apply.

On the conventional side, the 2026 conforming loan limits for Texas are $1,032,650 for a 2-unit, $1,248,150 for a 3-unit, and $1,551,250 for a 4-unit. No Texas county has been designated high-cost, so these limits are uniform statewide. The conforming loan limit is the maximum mortgage size that Fannie Mae and Freddie Mac will purchase from lenders — loans above that threshold become jumbo loans with different underwriting requirements.

The practical takeaway: most 2-4 unit deals in Texas fall well under both ceilings. A $650,000 fourplex in a Houston suburb is within FHA limits in most counties and well under the conventional conforming ceiling. The loan limit is almost never the binding constraint on a Texas small multifamily deal. What binds buyers is the down payment, the credit score, or the debt-to-income ratio — not the ceiling.

The Insurance Cost That Compounds Quietly

Here's the part most comparison articles mention but don't actually show you: the mortgage insurance math.

FHA charges two layers of MIP (Mortgage Insurance Premium). The upfront MIP is 1.75% of the loan amount, financeable into the loan — on a $400,000 purchase that adds $7,000 to your balance on day one. Then there's annual MIP running between 0.55% and 0.75% per year, collected monthly. For a buyer who puts less than 10% down, that annual MIP is permanent — it does not cancel. Ever. Not at 20% equity, not at 22% equity. The only way out is to refinance into a conventional loan or sell the property.

Conventional loans carry PMI (Private Mortgage Insurance), which has no upfront charge and cancels automatically by law when the LTV (Loan-to-Value ratio) — the outstanding balance divided by the property's value — reaches 78%. Under the Homeowners Protection Act, servicers must drop conventional PMI at that threshold without the borrower doing anything. A buyer who puts 15% down on a conventional loan in a normal-appreciation market typically hits 78% LTV in five to seven years. After that: zero insurance cost, permanently.

Run the crossover forward and the picture sharpens. The FHA buyer who puts 3.5% down saves $46,000 at closing on that $400,000 duplex. But at 0.55% annual MIP on a roughly $393,000 loan, they're paying around $180/month in insurance indefinitely. The conventional buyer at 15% down pays PMI for several years, then nothing. Depending on appreciation rate and how long you hold, the FHA buyer can pay more in cumulative insurance than they saved on the down payment. If you're buying with FHA, build the refinance into the plan from day one — not as a someday option, but as a dated milestone.

The Rental Income Trap (and How FHA Fixes It)

Take a hypothetical buyer — call him Eitan — who has solid income, decent credit, and has never owned a rental property. He wants to buy a fourplex in the Houston suburbs. His income alone barely covers the PITI (principal, interest, taxes, and insurance on the property), and he needs the rents to qualify.

Under conventional lending, Eitan has a problem. Fannie Mae guidelines generally require 12 months of documented rental income on tax returns before a first-time landlord can count rents toward their DTI (Debt-to-Income Ratio — the share of gross monthly income going to debt payments). Since Eitan has never been a landlord, that income doesn't count. His DTI comes out too high, and the loan is denied.

Under FHA, Eitan qualifies. FHA allows 75% of appraiser-projected gross rents from non-owner units to count toward qualifying income immediately — no prior landlord history required. On a fourplex where the three rental units collectively rent for $4,500/month, that's $3,375 in qualifying income added to his application from day one. That single rule difference is often the deciding factor for first-time investors with a regular W-2 income and no rental history. It's not a minor advantage — it's frequently the only path through.

DTI limits add another dimension. FHA allows DTI up to 57% via automated underwriting. Conventional Fannie Mae caps at 50%. A buyer carrying a car payment, student loans, and a regular mortgage can find their DTI sitting at 52% — which closes the conventional door entirely and still qualifies under FHA.

The FHA Self-Sufficiency Test — Where Austin Deals Break Down

If you're buying a triplex or fourplex with FHA financing, there's an additional test that the duplex buyer doesn't face. The Self-Sufficiency Test requires that 75% of gross market rents across all units — including the unit you'll occupy — equals or exceeds the full PITI payment. Duplex (2-unit) buyers are completely exempt from this test.

Work through a real Austin example. Suppose a buyer is looking at a fourplex priced at $550,000 in Austin. The fully amortized PITI on a 3.5%-down FHA loan at current rates comes to roughly $3,800/month. The appraiser estimates gross market rents at $1,400/unit across four units, or $5,600/month total. Seventy-five percent of $5,600 is $4,200 — that clears the $3,800 PITI. The deal passes.

Now consider what happens when the market shifts. Austin's multifamily vacancy rate ran approximately 14.5% in Q3 2025 — the highest among major Texas metros — and asking rents declined 4.3% year-over-year. If the same appraiser marks rents at $1,250/unit instead of $1,400, gross rents become $5,000 and 75% of that is $3,750. The test fails — even though the buyer's income is strong and the property pencils as a deal.

This is happening in Austin right now. The Self-Sufficiency Test is a rent-to-price solvency check, and in a market where prices remain elevated while rents have softened, the math stops working before the buyer's finances do. Houston and DFW, where rents relative to purchase prices are more favorable, tend to pass this test more consistently. Austin triplex and fourplex FHA buyers should run this math before falling in love with a property, not after.

Credit Scores, DTI, and Who Each Program Actually Serves

FHA's floor is 580 for the 3.5% down path. Borrowers between 500 and 579 can still qualify, but the required down payment jumps to 10%. Below 500, FHA is unavailable. Conventional financing starts at 620 in principle, but lender overlays — the additional requirements individual banks layer on top of agency guidelines — regularly push effective minimums to 700 or higher for investment properties. A buyer sitting at 640 FICO with a decent income and some savings has essentially one path through conventional underwriting: they will struggle to find a lender willing to approve a multifamily purchase. FHA is the only realistic door.

The house hacking strategy — buying a 2-4 unit property, living in one unit, and collecting rent from the others to offset the mortgage — is almost exclusively an FHA play for buyers without established credit or significant capital. It's how most small multifamily investors build their first unit of inventory. The owner-occupancy requirement, which demands genuine intent to occupy one unit as a primary residence, is what makes FHA available for these deals in the first place. Lenders and appraisers flag buyers who purchase a fourplex in a market with no evident connection to their life — buyers should be prepared to document legitimate intent.

The credit score needed to buy a fourplex with FHA in Texas is 580 for the standard path. What that doesn't tell you is that lender overlays can push the practical floor higher — many FHA lenders won't approve multifamily under 620 or 640. Shop multiple lenders, not just one.

When Does FHA Mortgage Insurance Go Away — and What to Do About It

The straight answer: for a buyer who puts less than 10% down, FHA annual MIP does not cancel on its own. Ever. The only exit routes are refinancing into a conventional loan once you have sufficient equity or selling the property. For buyers who put 10% or more down on an FHA loan, MIP cancels after 11 years — but at 10% down you're already within reach of conventional financing, which makes the FHA path less compelling to begin with.

The practical playbook for investors who use FHA to house-hack and then want to scale:

• Buy the 2-4 unit with 3.5% down using FHA and occupy one unit
• After 12 months of genuine owner-occupancy, the owner-occupancy requirement is satisfied — you can move out and rent all units
• Continue building equity through appreciation and principal paydown for another year or two
• When LTV reaches the point where a conventional refinance eliminates MIP and produces an acceptable rate, execute the refinance
• The old FHA loan is retired, you now hold a conventional loan with no PMI, and you've freed up your FHA eligibility for the next acquisition

This two-step sequence — FHA entry, conventional refi exit — is the deliberate scaling playbook that gets investors from zero to multiple units without needing a large capital base at the start. One FHA loan at a time, with the refi as the planned exit, not an afterthought.

On the question of holding multiple FHA loans simultaneously: FHA generally limits borrowers to one FHA loan at a time. There are narrow exceptions — documented relocation for employment, increased family size that renders the current home insufficient — but for an investor trying to build a portfolio, the intended path is to use FHA once, refinance out when equity allows, and then do it again. Using FHA as a bridge, not a permanent mortgage, is how it scales.

Is FHA or Conventional Better for a Texas Duplex or Fourplex?

The answer depends entirely on where you are financially, not on which loan sounds better in theory.

FHA tends to be the right call when:

• Your down payment is limited and the 3.5%-vs-15% delta is the difference between buying now and buying in several years
• Your credit score is below 700 and conventional lenders are adding overlays that make qualification difficult
• You have no landlord history and need projected rents — not documented history — to make the DTI work
• You're buying a duplex (exempt from the Self-Sufficiency Test) in a Houston or DFW submarket where rents support the math

Conventional makes more sense when:

• You have 20% or more to put down, which eliminates PMI entirely and removes the permanent MIP drag
• Your credit score is 720 or above, putting you in range for competitive conventional rates
• You're buying strictly as an investor — no occupancy required, no occupancy restriction
• You plan to hold the property long-term without refinancing, and you don't want MIP compounding over a decade or more
• You're building a portfolio and need to hold multiple financed properties simultaneously, which the one-FHA-loan rule constrains

The NOI (Net Operating Income — gross rents minus operating expenses, before debt service) and cap rate (NOI divided by purchase price) math on the property doesn't change between FHA and conventional, but the financing layer underneath it does. A property with a cap rate of 5.5% in a Houston suburb looks different when you're carrying permanent MIP versus no PMI. Run both scenarios with real numbers, including the insurance cost in each, before committing to either path.

The investors who get this decision wrong usually make one of two mistakes: they choose FHA for the low down payment without modeling the long-term insurance cost, or they rule out FHA because of the owner-occupancy requirement without recognizing that 12 months of occupancy is a very small ask for a lifetime of rental income from that unit. Both are recoverable mistakes — but knowing the trade-offs before closing is considerably cheaper than learning them after.
