15-Year vs. 30-Year Mortgage in Texas

The choice between a 15-year and 30-year mortgage in Texas comes down to monthly cash flow versus total cost. On the $310K median home with 10% down, a 30-year mortgage at 6.5% gives you a total PITI of $2,545/mo. A 15-year mortgage at 6.0% (15-year rates are typically 0.5-0.75% lower) pushes that to $3,136/mo — about $591 more per month. But you save approximately $211K in total interest and own the home free and clear in half the time.

At Texas's moderate price level, the $591 monthly difference between loan terms is a genuine decision point. Consider your career trajectory and income stability: if you expect steady income growth, the 15-year term locks in forced savings through faster principal reduction. If income is variable or you have other financial priorities (retirement savings, children's education), the 30-year term provides breathing room while you can still make occasional extra payments when cash flow allows.

With Texas's 1.8% property tax rate adding $465/mo to the payment regardless of loan term, the tax component narrows the relative difference between 15 and 30 years. Taxes and insurance are constants in both scenarios — only the principal and interest portion changes. This means the percentage increase from choosing a 15-year term is smaller than it appears from the P&I numbers alone, because taxes and insurance are already a large share of the total in a high-tax state like Texas.

Whichever term you choose, the TDHCA My First Texas Home program (up to 5% dpa grant) can ease the upfront burden. Use the full 15 vs 30 year mortgage comparison tool to model both scenarios with your actual numbers — including Texas-specific property taxes and insurance — and see the month-by-month difference in equity growth, interest paid, and total cost.

Common Questions

Is a 15-year mortgage worth it in Texas?+
A 15-year mortgage on the Texas median home saves approximately $211K in total interest compared to a 30-year term, but the monthly PITI jumps from $2,545 to $3,136 — an increase of $591/mo. It is worth it if you can comfortably afford the higher payment while still saving for retirement and maintaining an emergency fund. If the higher payment would strain your budget, the 30-year term with occasional extra payments is a safer approach.
What is the rate difference between 15 and 30 year mortgages?+
15-year mortgage rates are typically 0.5% to 0.75% lower than 30-year rates. As of 2026, if 30-year rates are near 6.5%, 15-year rates would be approximately 5.75%-6.0%. This rate advantage compounds the savings: you pay less interest per dollar borrowed AND you borrow for half as long. On the $310K Texas median home, this combination produces savings of roughly $211K over the life of the loan.
Can I refinance from a 30-year to a 15-year mortgage in Texas?+
Yes. If rates drop or your income increases after purchase, refinancing from a 30-year to a 15-year mortgage is a common strategy. Closing costs for a refinance in Texas typically run 1-2% of the loan balance. The breakeven on those costs is usually 2-3 years, so it makes sense if you plan to stay in the home at least that long. Alternatively, you can simply make extra payments on your 30-year loan to achieve a similar effect without paying refinance fees.
