Mortgage Calculator in Sullivan City, TX

In Sullivan City, Texas, most buyers use a 30-year fixed-rate mortgage. Your monthly payment has four components lenders call PITI: principal, interest, property taxes, and homeowners insurance. Texas property taxes average 1.6–2.2% of assessed value annually—on a $135,000 home that's roughly $203/month. Factoring in insurance and any HOA fees gives you your true monthly housing cost.

Down payment size dramatically affects both your monthly payment and whether you need private mortgage insurance (PMI). Conventional lenders waive PMI once you reach 20% equity. On a $135,000 home in Sullivan City, 20% down is $27,000. If that's out of reach, FHA loans allow 3.5% down, and first-time buyer programs in Texas can help with down payment assistance.

Use the calculator above to test different scenarios—what happens if you put 15% down instead of 10%? What if rates drop to 6.5%? Running these numbers before you make an offer in Sullivan City means you walk into negotiations knowing exactly what you can afford.

  • Move-up buyers evaluating a higher price point in a new neighborhood
