Houston mortgage calculator
A median-priced Houston, TX home at 6.75% over 30 years, with Texas property tax of 1.63% and $3,400 a year of homeowners insurance. Every figure below is computed on our amortising engine — nothing is estimated in the browser.
$2,741 a month, all in
Principal and interest are $1,885; escrow and PMI add the rest. Over the full term the loan costs $388,071 in interest. Discounted at 5%, buying here has a net present value of $95,755 ($328,700 in today’s dollars).
Within Texas, Houston is 4th of the 10 Texas markets covered here, between Austin at the top and El Paso at the bottom of a 2.07x spread. A state-level median hides most of that.
Rents here are high relative to prices — a rent index of 1.05 against a price index of 0.95. That combination favours buying sooner, because the payment you avoid is larger relative to the price you pay.
At $323,000 to buy and $1,890 a month to rent, the price-to-rent ratio is 14.2 — low. Ownership tends to pull ahead quickly at that level, and the binding question is transaction costs rather than the monthly comparison.

Where these numbers come from
Texas medians come from editorial and are refreshed weekly. The Houston figures index those state medians to the local market, so they track the same feed rather than going stale. Insurance and the state income tax rate are editorial. Treat everything here as a planning estimate, not a quote.
