The mortgage is half the payment.
Texas has no state income tax, and property taxes carry that load. In Tarrant County the combined rate lands in a band that depends on the city and school district. Run an address and the worksheet pulls the actual appraised value from Tarrant Appraisal District public records and shows the honest range.
Estimate the taxes on an address.
Three levers that change the real bill
File the homestead exemption
If you live in the house, this is free money: it cuts the taxable value (the school-district exemption is $140,000) and caps annual appraised-value increases at 10%. It does not transfer with the sale. New owners must file with TAD, and filing costs nothing. (Tex. Tax Code 11.13(b); $140,000 since tax year 2025)
Protest the appraisal
The appraised value is an opinion and you can contest it every year. The window is short: typically May 15 or 30 days after your notice arrives, whichever is later. A well-documented protest with comparable sales regularly moves the number.
Know your taxing units
Two houses a mile apart can carry meaningfully different rates because city, school district, and special districts stack differently. That is why this tool gives a band and not a quote. The exact stack is on the parcel's TAD page.

Want the full carrying-cost picture?
Taxes are one line. Insurance, HOA, and the exemption math decide whether a house actually fits the budget, and that read changes block by block. If you are pricing a purchase or wondering whether your current appraisal is worth protesting, leave your info and I will run the numbers on the specific property. No charge for the read.
