Understanding Your Texas Mortgage Payment
A mortgage payment in Texas looks different from most other states — not because of income tax (Texas has none), but because of property taxes that are among the highest in the nation. The average effective rate in Texas hovers around 2.1%, nearly double the U.S. national average of 1.1%. This makes your total monthly housing cost significantly higher than what a basic principal-and-interest calculator would suggest.
How Texas Property Tax Impacts Your Monthly Payment
On a $350,000 home, the property tax difference between Texas and a state with the national average rate adds roughly $290/month to your payment. This is why it's critical to use a Texas-specific mortgage calculator that accounts for accurate county-level tax rates rather than a generic national tool.
Texas property taxes fund local services — schools, roads, emergency services — that other states pay for with income taxes. The trade-off: no state income tax on your paycheck, but a larger escrow payment each month. For many buyers relocating to cities like Dallas or Austin from high-income-tax states, the net effect is still favorable, especially at higher income levels. Some newcomers prefer to rent first to get to know the area before committing to a purchase.
The Homestead Exemption Advantage
If the property is your primary residence, Texas law provides a mandatory $140,000 homestead exemption on the school district portion of your property taxes (2026 figure). This can save homeowners $1,400-$1,700 per year depending on the local school tax rate. Additional exemptions are available for homeowners over 65 or with disabilities, which also freeze school tax amounts.
What's Included in PITI?
Your total monthly payment — often called PITI — includes four components:
- Principal: The portion that reduces your loan balance
- Interest: The cost of borrowing, determined by your rate and remaining balance
- Taxes: Property taxes collected through your escrow account
- Insurance: Homeowners insurance (and flood insurance if in a flood zone)
If your down payment is less than 20%, PMI (Private Mortgage Insurance) adds a fifth component until you reach 20% equity. HOA fees, while not technically part of PITI, are another recurring cost factored into affordability calculations.
Tips for Lowering Your Texas Mortgage Payment
- Protest your property tax appraisal annually — successful protests can save hundreds per year
- Put at least 20% down to avoid PMI (saves $100-$200+/month on most loans)
- Shop multiple lenders — even a 0.25% rate difference saves thousands over the life of the loan
- File your homestead exemption immediately after closing — don't leave money on the table
- Consider a 15-year term if you can afford the higher payment — you'll pay far less total interest
