Houston Texas Mortgage Calculator 2026

Houston offers housing costs that fall below the national average. At a median home price of $327K -- about 22% below the U.S. median -- the city presents realistic home-ownership opportunities for a wider range of income levels.

The income-to-home-price ratio of 5.2x means buying is possible but requires disciplined budgeting. A household at the median income of $63K can qualify for the median-priced home, though the monthly payment may consume a larger share of take-home pay than is ideal.

The market in Houston has been relatively stable, giving buyers more time to evaluate options and negotiate terms without the urgency of a rapidly shifting price environment.

Houston has no zoning laws — the only major US city without them. This means a townhome development can appear next to a single-family neighborhood overnight, affecting property values unpredictably. Deed restrictions in specific subdivisions provide the only protection, and they expire (typically after 25-30 years). Flood risk is the other defining factor: homes in the 100-year floodplain require mandatory flood insurance ($1,500-$5,000/year), and Harvey in 2017 proved that even homes outside mapped zones can flood.

Monthly housing costs extend well beyond principal and interest. For a median-priced home of $327K with 20% down at approximately 6.8%, the principal-and-interest payment comes to around $1,705 per month. Add property taxes of roughly $450/mo (1.65% rate) and homeowners insurance near $136/mo, and the total PITI lands around $2,291 per month.

Using the 28% rule of thumb, a household would need a gross annual income of approximately $98,186 to comfortably carry that payment. These are estimates -- actual numbers depend on credit score, loan type, and lender terms.

The Energy Corridor (west Houston) offers executive homes at 40% below comparable properties inside the Loop, but faces boom-bust cycles tied to oil prices. The Heights and Montrose have gentrified fully — expect $700K+ for a renovated bungalow. For value, look at Spring Branch and Garden Oaks: inside Beltway 8, good schools, and still under $500K for updated 3-bedroom homes.

Texas levies no state income tax, which boosts take-home pay for residents of Houston. However, property taxes average 1.6% statewide, so the overall tax picture depends on whether you rent or own.

For a home priced at $327K, annual property taxes of approximately $5,396 are a significant recurring cost that lenders include in qualifying calculations. Understanding the full tax picture helps set realistic expectations for both monthly cash flow and long-term affordability.

1. Texas Housing Finance Authority (HFA) — offers below-market mortgage rates and down payment assistance for income-qualified buyers.

2. Texas has no state income tax, meaning more of your paycheck is available for housing costs and saving toward a down payment.

3. HUD-approved housing counseling agencies in Houston offer free or low-cost guidance on mortgage readiness and local assistance programs.

4. FHA loans are widely used in Houston — they require as little as 3.5% down ($11K on the median home) and are available to borrowers with credit scores as low as 580.

5. USDA and VA loans may apply to eligible buyers — USDA covers rural/suburban areas, VA loans require no down payment for qualifying veterans.

With a one-bedroom rental averaging around $1,199/mo and total ownership costs near $2,291/mo for the median home, buying carries a premium of roughly $1,092/mo in year one over renting. However, that gap narrows as equity builds and rent prices rise.

A common rule of thumb: if you plan to stay at least 3-5 years, buying in Houston is likely the stronger financial move. Shorter timelines typically favor renting given transaction costs (closing costs, agent commissions) that take time to recoup.

The local price-to-rent ratio — home price divided by annual rent — is approximately 23x. Above 20x often tips toward renting unless you plan a long-term stay.

Never skip the flood history check. Pull the property's FEMA flood zone designation AND check Harris County Flood Control District maps for actual Harvey inundation data. A home outside the 100-year floodplain that flooded in Harvey is a red flag that maps haven't caught up to reality. Budget $2,000-$4,000/year for flood insurance even if not required — it's cheap peace of mind in Houston.

1. Compare lender-reviewed estimates, not just rough pre-qualification ranges. In a competitive market, sellers often prefer buyers with stronger underwriting support.

2. Target homes priced 10-15% below the median ($284K) to give your budget more breathing room after move-in costs.

3. Property taxes here run above 1.5%. Ask your lender to include the exact PITI (not just principal and interest) in your approval letter so you see the true monthly cost.

4. Take advantage of the no-income-tax environment — redirect what you'd pay in state tax toward a larger down payment or bi-weekly mortgage payments to save on interest.

5. Compare offers from at least three lenders. A 0.25% difference in rate on $327K saves roughly $19,620 over 30 years.

6. Schedule a home inspection even in competitive markets — skipping it to win a bid can cost far more than the inspection fee if hidden issues emerge after closing.

7. Check your credit report 6 months before applying — disputing errors takes time, and each point above 740 can improve your rate meaningfully.
