Most online real estate calculators are national. They ignore the things that actually move your numbers in Texas: property tax rates that run 1.8–2.3% of value depending on the county, a homestead exemption that knocks $140,000 off school taxes, owner's title policies priced by a state-promulgated rate schedule, and no state income tax or transfer tax. Every tool here uses those Texas rules, so the estimate you see is the one your lender and title company will recognize.
How KAT Realty's flat fee changes the math
KAT Realty Group is a full-service flat fee real estate service: buyer representation for $4,999 and seller listing for $5,999, anywhere in Texas. On the seller side that replaces a 2.5–3% listing commission. On the buyer side, when the seller pays a buyer-agent fee, we keep the flat $4,999 and the rest is rebated to you at closing. Several calculators show both the traditional number and the flat-fee number so you can see the difference on your own home.
Frequently asked questions
Are these calculators free?
Yes. Every tool is free, requires no sign-up, and never asks for your email. Results appear instantly as you type.
How accurate are the estimates?
They use current Texas rules — TDI title rates effective March 1, 2026, typical county tax rates, the $140,000 school homestead exemption — but they are estimates. Your lender's Loan Estimate and the title company's settlement statement are the final numbers.
Do the tools work anywhere in Texas?
Yes. County tax rates cover the Austin, Dallas–Fort Worth, Houston and San Antonio metros with an 'Other Texas county' option, and every tool lets you override the rate.
Is flat fee real estate legal in Texas?
Flat fee real estate is fully legal in Texas. KAT Realty agents operate under the same TREC licensing requirements as traditional agents.
