How much is a monthly mortgage payment in Texas?
Here's a worked example for Texas. On a $400,000 home with 20% down ($80,000), you'd borrow $320,000. At a 6.55% 30-year fixed rate — the current U.S. national average — the principal and interest come to about $2,033 per month. Adding Texas's average effective property tax of 1.4% ($5,600 a year, or $467 a month) brings the core housing cost to roughly $2,500 per month, before home insurance and any HOA dues. Enter your own price, down payment, and rate in the calculator above to get your exact number.
Property taxes in Texas
Texas's average effective property-tax rate is 1.4%, which is above the U.S. average of 0.90% and ranks among the higher of all states. On the $400,000 example home that's $5,600 per year. Rates are set locally, so your actual county or city rate can differ — check your county assessor's site and adjust the property-tax field above to match. Texas also levies no state income tax, which can meaningfully change how much home you can afford compared with a high-income-tax state at the same salary.
The levers that move this number — deposit size and PMI, rate shopping, insurance, HOA dues — work the same way everywhere. We cover them properly in how mortgage payments work and down payment & PMI rather than repeating them on every state page.

Conforming loan limits in Texas — when you cross into jumbo
Limits are set county by county, not state by state. For 2026 the national baseline is $832,750; above your county's limit you're into jumbo territory.
Texas is straightforward here: all 254 counties sit at the national baseline of $832,750. There are no high-cost designations anywhere in the state, so the same threshold applies whether you're buying in a metro or a rural county. With 20% down that's a purchase price of roughly $1,040,938 before a conventional loan becomes a jumbo — above most of the state's market, so relatively few Texas buyers hit it.

Frequently asked questions
Is property tax the same everywhere in Texas?
No — property tax rates vary by county and even by city within Texas. The calculator starts from Texas's statewide average effective rate of 1.4%, so check your local assessor's site for your exact county rate and adjust the field to match.
What's the conforming loan limit in Texas?
All 254 counties in Texas use the 2026 national baseline of $832,750 for a one-unit property — there are no high-cost designations in the state. Borrow above that and you're into jumbo territory, with different rates and underwriting.
Does Texas having no state income tax affect what I can afford?
It affects your take-home pay rather than the mortgage itself. The affordability table above works from gross income, so at the same salary a Texas buyer keeps more of it than someone in a high-income-tax state — which in practice supports a larger monthly payment than the gross-income maths alone suggests.
