Texas Mortgage Calculator

Texas mortgage calculator: estimate the full payment, not just the loan

The calculator on this page estimates a monthly payment for a home anywhere in Texas. In Texas, the loan itself is often the predictable part. Property tax, homeowners insurance, and HOA dues can swing the total far more from one neighborhood to the next, so this guide explains which numbers to plug in, where to find them, and how FHA, VA, and conventional loans change the result. Summit Lending LLC (NMLS 2394434) is a mortgage broker licensed in Texas. We compare loans from multiple wholesale lenders and can turn your estimate into a real quote.

Texas numbers to start with

Redfin reported a statewide median sale price of about $333,611 for August 2026, down 1.3% from a year earlier. About 26,159 homes sold, the typical home took around 68 days to sell, and roughly 180,524 homes were listed, about six months of supply (Redfin Texas data). The Texas Real Estate Research Center at Texas A&M put the July statewide median at $339,000 (TRERC Texas Housing Insight). More inventory and longer selling times give buyers room to negotiate, including seller-paid closing costs or a rate buydown, which you can test in the calculator by lowering the rate.

Rates set the base of every estimate. Freddie Mac's weekly survey put the average 30-year fixed rate at 7.28% for the week of October 1, 2026, up from 7.03% a week earlier and 6.34% a year ago. The 15-year average was 6.60% (Freddie Mac PMMS; history on FRED). Those are national averages for borrowers with strong credit and roughly 20% down, not Texas quotes. Freddie Mac publishes a new reading every Thursday (PMMS page), so if you are running numbers a few weeks from now, update the rate first.

Why property tax deserves its own line

Texas property taxes are set locally by counties, cities, school districts, and special districts such as MUDs, which are common in newer subdivisions around Katy, Conroe, and Pearland. Two homes at the same price can carry very different tax bills. Use the tax rate for the exact address, which you can find on the appraisal district or tax office website, rather than a statewide average.

A homestead exemption lowers the taxable value of your primary home. After voters approved Proposition 13 in 2025, the school district homestead exemption is $140,000 (Ballotpedia on Proposition 13; Texas Comptroller exemptions). You apply with your appraisal district after you move in, so a seller's tax bill may reflect exemptions you will not have in your first year. We build the escrow estimate around what you will actually pay.

Worked example: a $335,000 Texas home

Take a $335,000 home, close to the statewide median, with 10% down. The loan is $301,500. At 7.28%, principal and interest on a 30-year fixed is about $2,063 a month. A year ago, at 6.34%, it would have been about $1,874. A 15-year fixed at 6.60% raises the payment to about $2,643 but brings total interest over the full term down to about $174,238, versus about $441,144 on the 30-year at 7.28%.

On top of that come property tax, homeowners insurance, PMI with less than 20% down, and HOA or MUD charges. In much of Texas, taxes and insurance together can add a large share on top of principal and interest, so get an insurance quote and the tax rate for the address before you settle on a price.

How the loan type changes your Texas result

Most online calculators assume a conventional loan with a fixed rate, which can make the number look better or worse than what you would actually get. Here is how the same $335,000 Texas home changes by program, using the 7.28% survey average as a stand-in rate. Your actual rate will differ by program and profile.

Conventional

Qualified buyers can put as little as 3% down on a one-unit primary home, which is $10,050 on $335,000 (Fannie Mae eligibility matrix). Below 20% down you pay private mortgage insurance, and you can ask to cancel it once the balance reaches 80% of the original value (CFPB on PMI). PMI is priced by credit score and down payment, so add it as a separate line in the calculator rather than guessing.

FHA

FHA requires 3.5% down with a 580 or higher score (HUD FHA overview). It also adds two insurance costs a basic calculator often skips: an upfront premium of 1.75% that is usually financed into the loan, and an annual premium paid monthly. For a base loan of $726,200 or less with more than 95% loan-to-value, the annual rate is 0.55% (HUD Mortgagee Letter 2023-05). On $335,000 with 3.5% down, the base loan is $323,275, the upfront premium adds $5,657, and principal and interest on $328,932 is about $2,251 at 7.28%. The monthly premium adds roughly $148, for about $2,399 before taxes and insurance. For 2026, one-unit FHA limits are $571,550 in the Austin metro, $563,500 in Dallas-Fort Worth, and $557,750 in San Antonio, so this price fits in every major metro.

VA

Eligible veterans and service members can buy with no down payment and no monthly mortgage insurance (VA purchase loans). A one-time funding fee applies unless you are exempt, and for first use with less than 5% down it is 2.15% of the loan (VA funding fee). Financing that fee on $335,000 brings the loan to about $342,202, with principal and interest near $2,341 at 7.28%.

USDA

USDA guaranteed loans allow no down payment in eligible rural areas for households under the income limits (USDA guaranteed loans). Many communities outside the major metros can qualify, while most of the large cities do not. Check an address on the USDA eligibility map before you count on it.

2026 loan limits in Texas

The 2026 conforming loan limit is $832,750 for a one-unit home in all 254 Texas counties (FHFA announcement, FHFA county file). FHA limits vary by metro, from the $541,287 national floor in many counties up to $571,550 in the Austin area (HUD announcement, HUD lookup).

Closing costs and title insurance

Your down payment is not the only cash you need. Lender fees, appraisal, title, and prepaid taxes and insurance add up. In Texas, title insurance premium rates are set by the Texas Department of Insurance, so the base premium is the same no matter which title company you use (TDI title insurance). Lender fees and rates are where comparison shopping pays off, which is why we show you more than one lender.

Down payment help in Texas

The Texas Department of Housing and Community Affairs offers My First Texas Home and My Choice Texas Home, each with down payment assistance of up to 5% through participating lenders (TDHCA program chart). The Texas State Affordable Housing Corporation also offers up to 5% assistance through Homes for Texas Heroes and Home Sweet Texas (TSAHC programs). Income and price limits apply. Our Texas first-time home buyer guide covers the details.

From a calculator estimate to a real number

1. Run a few scenarios here. Try two prices, two down payments, and both a 30-year and 15-year term so you know your range.
2. Get preapproved. A preapproval means a lender checked your credit, income, and assets. The CFPB points out that lenders use the terms prequalification and preapproval differently, so ask what was verified (CFPB comparison). Several mortgage credit checks within 45 days count as one inquiry for most scoring models, so shopping does not hurt your score more than once (CFPB on credit checks).
3. Compare Loan Estimates. Lenders must send a Loan Estimate within three business days of your application, and the standard format makes side-by-side comparison easy (CFPB on Loan Estimates).
4. Watch your debt-to-income ratio. Lenders compare your monthly debts, including the new payment, to gross monthly income (CFPB on DTI). A payment that fits your budget can still be too high for a program limit, or the reverse.
5. Check the final numbers. Your Closing Disclosure arrives at least three business days before closing. Compare it to your Loan Estimate line by line (CFPB on Closing Disclosures).
