Houston Mortgage Calculator
Estimate your monthly payment and plan your budget with confidence.
Estimate a monthly payment below. One caution specific to this area: a calculator that only asks for price, down payment, and rate will understate a Houston-area payment, sometimes substantially.
Estimates are for planning purposes only. Contact a licensed lender for an accurate quote.
What a basic calculator leaves out here
Property taxes in Texas are levied by several overlapping entities — county, city, school district, and often a MUD and other special districts — and there is no state income tax. The combined rate for a specific address is the figure that matters, and it is not the county rate alone. Because there is no state income tax, Texas property tax rates are generally higher than in states that levy one, so the tax portion of a Houston-area payment is a larger share of the total than a national calculator's default assumes.
Homeowners insurance in the Gulf Coast region also reflects windstorm and flood exposure, and flood insurance may be required by your lender depending on the property's floodplain designation. Where a home is in an HOA, those dues are separate again and are usually not escrowed with the mortgage payment.
Get the real number before you shop
The practical step is to get a written estimate from a licensed lender for the specific price range and areas you're considering, so the tax rate and insurance figures reflect real addresses rather than defaults. That also tells you what you're actually approved for, which is a different question from what a calculator says you can afford.
Texas also offers a homestead exemption that reduces the taxable value of a qualifying primary residence, which affects the tax portion of the payment — but the exemption depends on your own circumstances and must be applied for, so don't assume the prior owner's tax figure will be yours.
Frequently Asked Questions
Why is my estimated payment higher than the calculator suggested?
+
Usually taxes and insurance. Texas has no state income tax and correspondingly higher property tax rates, levied by several overlapping entities — county, city, school district, and often a MUD. Gulf Coast insurance costs and any required flood coverage add more, and HOA dues are separate again.
What is the Texas homestead exemption?
+
It reduces the taxable value of a qualifying primary residence, lowering the property tax portion of your payment. It has to be applied for and depends on your own circumstances, so the previous owner's tax bill is not a reliable guide to what yours will be.
Should I get pre-approved before I start looking at homes?
+
Yes. A written pre-approval from a licensed lender tells you what you can actually borrow, gives you real tax and insurance figures for the areas you're considering, and makes your offer materially stronger when you find the right home.
Will I need flood insurance?
+
It depends on the specific property's floodplain designation, and lenders generally require it where a home sits in a designated flood zone. Because floodplain maps are revised over time, verify the current designation for the exact address rather than relying on the neighborhood's reputation.
