Dallas Mortgage Calculator
Your real payment in Dallas is more than principal and interest. Property tax here often runs 2 percent of the price or more a year, so it belongs in the number from the start. The rate is preset to the Freddie Mac Primary Mortgage Market Survey 30 year fixed average of 7.40 percent as of October 15, 2026; change it to your own quote.
Year by year schedule
How the numbers work
- Principal and interest use the standard fixed rate payment formula for the term you pick.
- Property tax: our estimate takes the rate times the price, divided by twelve. Your real bill uses the appraisal district taxable value after any homestead exemption, so it is often lower. The Dallas preset is the 2026 rate the Dallas County Tax Office lists (2.25076 per $100), which includes a county rate on the November 3, 2026 ballot; the Frisco and Rockwall presets are 2026 rates from our Collin County and Rockwall County pages. All are before any homestead exemption. For one address, use the total rate on its county tax bill; the Home Check shows whether it sits in a MUD or water district.
- PMI applies only below 20 percent down on a conventional loan. Enter the rate from your lender quote.
- Extra principal shows how much interest you save and how much sooner the loan is paid off.
Questions people ask
How is a mortgage payment calculated?
Principal and interest come from the loan amount, the monthly rate and the number of payments. Property tax, insurance, HOA dues and PMI are added on top to get the full monthly payment.
What property tax rate should I use in Dallas?
For 2026, inside the City of Dallas and Dallas ISD the total is about $2.25 per $100 of value (2.25076, which includes a Dallas County rate on the November 3, 2026 ballot). Suburbs and other school districts differ, and a homestead exemption lowers the taxable value once the home is yours.
When does PMI go away?
On a conventional loan, federal law ends PMI automatically when the balance is scheduled to reach 78 percent of the original value, as long as you are current on payments. You can ask in writing to remove it at 80 percent if your payment history is good, there is no second lien and the home has not lost value.
