Houston First-Time Home Buyer Guide: Loans & Programs (2026)

Houston is one of the more attainable major metros for a first purchase — but Texas property taxes and local assistance programs change the math in ways a generic national guide misses. Here is how the numbers actually work.

TL;DR

• Down payment is smaller than you think — 3% conventional or 3.5% FHA, and Texas assistance programs can cover much of it.
• Property taxes drive the payment. Harris County combined rates commonly run 2% to 2.7% of assessed value because Texas has no state income tax. This can add hundreds per month.
• Two statewide agencies help first-time buyers: TDHCA (My First Texas Home) and TSAHC (Homes for Texas Heroes / Home Sweet Texas), plus a Harris County program for buyers outside the City of Houston limits.
• First-time is defined loosely — most programs mean "no primary residence owned in the last three years," with waivers for veterans and target areas.
• File your homestead exemption after closing to cap assessed-value growth and lower the tax portion of your payment.

What "first-time buyer" means in Texas

The label is more generous than it sounds. Under the rules used by TDHCA and most bond programs, a first-time buyer is anyone who has not owned and occupied a primary residence in the previous three years. If you rented after a divorce, sold a home years ago, or only ever co-signed on someone else's mortgage, you likely still qualify.

Two additional carve-outs matter in the Houston area:

• Veterans are exempt from the first-time requirement on most Texas programs.
• Federally designated target areas — certain census tracts inside Harris County — waive the three-year rule for any buyer.

So before you assume you have missed the window, check the specific program's definition. It rarely matches the everyday meaning of "first home."

The real Houston down payment picture

The single most common myth is that you need 20% down. You do not. Here is what the entry points actually look like on a representative Houston-area purchase.

| Program | Minimum down | On a $340,000 home | Notes | | --- | --- | --- | --- | | Conventional 97 | 3% | $10,200 | At least one borrower must be a first-time buyer | | HomeReady / Home Possible | 3% | $10,200 | Income limits apply; reduced mortgage insurance | | FHA | 3.5% | $11,900 | Score as low as 580; flexible on credit | | VA (eligible veterans) | 0% | $0 | No monthly mortgage insurance | | USDA (eligible outlying areas) | 0% | $0 | Household income caps; rural/suburban zones |

The 20% figure only matters for avoiding mortgage insurance, not for getting approved. For a deeper comparison of the two main paths, see our FHA vs conventional guide and the conventional loan overview. If you want a Texas-specific lender view, browse Texas conventional loan officers or Texas FHA specialists.

Why Texas property taxes change everything

This is the part national calculators get wrong for Houston. Texas collects no state income tax, so it leans on property tax to fund schools, counties, and municipal utility districts. Harris County combined effective rates commonly land between 2% and 2.7% of assessed value, and newer master-planned communities carrying MUD (Municipal Utility District) debt can run higher in their early years.

That difference is not a rounding error — it can be the largest swing in your monthly payment.

Worked example: two identical loans, different tax worlds

Consider a $340,000 home financed with a conventional loan at 5% down (a $323,000 loan). We will use a hypothetical 6.5% rate for illustration only — this is not a rate quote or prediction.

| Line item | Houston (2.4% tax) | Lower-tax metro (1.0% tax) | | --- | --- | --- | | Principal & interest | ~$2,041 | ~$2,041 | | Property tax (monthly) | ~$680 | ~$283 | | Homeowners insurance | ~$210 | ~$150 | | Private mortgage insurance | ~$135 | ~$135 | | Estimated monthly (PITI) | ~$3,066 | ~$2,609 |

Same house price, same loan, roughly $457 more per month in Houston — almost entirely from taxes and insurance. The lesson: when you run affordability, plug in a realistic Harris County tax rate, not a national average. Our affordability calculator lets you set the tax and insurance inputs directly.

Two things soften this over time:

1. The homestead exemption reduces your taxable value and caps annual assessed-value increases at 10% once the home is your primary residence. File it with the Harris County Appraisal District after closing.
2. Insurance shopping matters more here because Gulf Coast wind and flood exposure raises premiums. Get quotes early; flood zone status can change the number substantially.

Texas down payment assistance programs

Two statewide agencies dominate, and both layer on top of a normal first mortgage.

TDHCA — Texas Department of Housing and Community Affairs

• My First Texas Home — a 30-year fixed loan (FHA, VA, USDA, or conventional) paired with down payment and closing-cost assistance, typically up to 5% of the loan amount. Reserved for first-time buyers and veterans.
• My Choice Texas Home — similar assistance without the first-time restriction, so repeat buyers can use it.
• Texas Mortgage Credit Certificate (MCC) — a federal tax credit worth up to $2,000 per year against your mortgage interest, claimed via IRS Form 8396. It can be combined with the loan programs above.

TSAHC — Texas State Affordable Housing Corporation

• Homes for Texas Heroes — enhanced assistance for teachers, first responders, corrections officers, nurses, EMS, and veterans.
• Home Sweet Texas — the general-population version for buyers under the income limits.
• Assistance usually comes as a grant (never repaid) or a forgivable/deferred second lien covering 3% to 5% of the loan, plus an optional MCC.

Both agencies set income limits that vary by county and household size, and both require you to work through an approved participating lender and complete a homebuyer education course. Because the eligibility bands and occupation bonuses differ, it genuinely pays to price a TDHCA package and a TSAHC package side by side.

Harris County assistance

For homes located in unincorporated Harris County or participating cities outside the City of Houston limits, the county's Community Services Department has periodically offered down payment assistance for income-eligible first-time buyers, often structured as a forgivable loan. Funding is grant-cycle dependent, so availability changes — confirm current status directly with the county before you build it into your plan. Buyers inside Houston city limits should check the City of Houston's own homebuyer assistance program separately.

Comparing your loan options for a Houston purchase

| Feature | FHA | Conventional | VA | USDA | | --- | --- | --- | --- | --- | | Minimum down | 3.5% | 3% | 0% | 0% | | Minimum credit (typical) | 580 | 620 | 580–620 | 640 | | Mortgage insurance | Upfront + monthly, often for life of loan under 10% down | PMI, cancels at 78% LTV | None | Guarantee fee, lower than FHA | | Best fit | Lower credit, higher DTI | Stronger credit, long-term hold | Eligible veterans | Eligible outlying Houston areas | | Pairs with TX assistance | Yes | Yes | Yes | Yes |

For the mortgage insurance mechanics that drive lifetime cost, read our PMI explainer. If your debt load is tight — student loans, a car payment — the DTI ratio guide shows what underwriters actually count, and FHA's more forgiving back-end limits can be the deciding factor.

A realistic Houston buyer scenario

Meet a hypothetical first-time buyer earning $78,000, with a 690 credit score and about $15,000 saved.

• Target price: $340,000, a common range for a starter home in Houston's suburban belt.
• Loan choice: Conventional 97 at 3% down = $10,200 down, leaving room for closing costs.
• Assistance: A TSAHC Home Sweet Texas grant of 4% ($13,600 on the roughly $329,800 loan) covers the down payment and a chunk of closing costs, freeing the $15,000 in savings for reserves and moving.
• MCC: A mortgage credit certificate returns up to $2,000 a year at tax time.
• Payment reality: With Harris County taxes and Gulf Coast insurance, budget a PITI closer to $3,000 than the $2,000 principal-and-interest figure a bare mortgage calculator shows.

The takeaway is not the exact numbers — rates and program terms move — it is the shape: modest down payment, assistance layered on top, and taxes plus insurance as the line items that actually determine what you can afford.

Before you shop: three Houston-specific moves

1. Pull your credit and check program floors. Most Texas assistance requires 620 to 640. See our credit score guide for the pricing bands.
2. Underwrite the tax rate, not the average. Look up the specific rate for the neighborhood and any MUD district before you fall in love with a house.
3. Verify your loan officer's license. Every legitimate Houston MLO is searchable on NMLS Consumer Access. Confirm the license is active in Texas before you share documents. Our questions to ask a loan officer list is a good screening tool.
