Texas Mortgage Calculator Guide

The temptation with a mortgage calculator is to focus on principal and interest and call the job finished. In Texas, I would use this page to keep the other moving parts visible: down payment, property-tax assumptions, insurance, possible PMI, and cash-to-close assistance. The current benchmark is $299,400, and this guide covers 50 city calculators. That sequence keeps the first estimate simple without hiding the local details that can change a real monthly payment.

Down-payment comparison

What 5%, 10%, and 20% down could look like in Texas

These examples use the $299,400 statewide benchmark, a 6.75% 30-year fixed planning rate, the 1.58% midpoint property-tax assumption, and 0.35% annually for homeowners insurance. PMI is illustrated at 1% annually below 20% down.

The examples do not include HOA dues, closing costs, discount points, lender fees, flood insurance, or property-specific insurance adjustments. Change the city calculator inputs before using a result for a budget.

Local variation

Why one Texas estimate should not represent every city

The available city-page tax assumptions run from 1.27% for Midland to 2.06% for Pearland, with a midpoint of 1.58% used in the statewide examples. That spread is a reminder to verify the parcel, assessment, exemptions, and taxing district before relying on a monthly number. Midland and Dallas and Pearland are useful starting points for seeing how the planning assumptions vary inside Texas.

These are effective-rate planning assumptions from 2024 public data, published in this system in 2026. Actual tax bills depend on assessed value, exemptions, levies, and the property's taxing districts.

Cash-to-close research

Homebuyer assistance in Texas

The state-level research list currently contains 6 programs. Homes for Texas Heroes Program (TSAHC) and Home Sweet Texas Home Loan Program (TSAHC) are included as a place to begin, not as a promise of approval. Funding, income limits, first-time-buyer definitions, participating lenders, and eligible locations can change, so I would confirm the current rules before counting assistance as cash available at closing.

Offers down payment assistance and mortgage credit certificates to teachers, police officers, firefighters, EMS personnel, and veterans.

A practical review

Before relying on a Texas payment estimate

01

Replace the statewide Texas benchmark with the price of the homes actually being considered.

02

Open the relevant city calculator and verify the property-tax assumption against the parcel or local assessor.

03

Get a property-specific homeowners-insurance estimate and add HOA dues when they apply.

04

Compare several interest rates and down payments instead of budgeting from one optimistic scenario.

05

Confirm assistance rules with the official program source before reducing estimated cash to close.

Common questions

Planning a mortgage in Texas

How much is an estimated mortgage payment in Texas?

Using the current $299,400 statewide home-value benchmark, 20% down, a 6.75% 30-year planning rate, the 1.58% midpoint property-tax assumption, and a 0.35% insurance assumption, the estimated monthly payment is $2,034. Actual property, loan, tax, and insurance details can differ.

Does the Texas mortgage estimate include property taxes?

Yes. The statewide examples use a 1.58% midpoint from the available city-page assumptions. A property-specific estimate should use the actual parcel, assessment, exemptions, and local taxing districts.

How much down payment should I compare in Texas?

The page compares 5%, 10%, and 20% down. A smaller down payment reduces upfront cash but can increase the loan balance and may add mortgage insurance. Program and loan requirements vary.

Where should I verify Texas homebuyer assistance?

Start with each linked official program source. Verify current funding, income limits, purchase-price limits, property rules, participating lenders, and first-time-buyer definitions before relying on assistance.
