Understanding a Houston Mortgage Payment
Buyers moving to Texas often anchor on the sticker price and get caught by the monthly number. There is no state income tax here, which is genuinely a saving — but the trade-off is property tax, and Fort Bend County sits at the higher end of it. A combined rate between roughly 2.5% and 3.5% of assessed value is typical, which on a $450,000 home is somewhere near $940 to $1,310 a month before principal, interest, or insurance.
Most of that variation comes from Municipal Utility Districts. A MUD is a special taxing entity that financed the water, sewer, and drainage infrastructure for a subdivision, and its levy sits on top of the county, city, and school district rates. Newer master-planned sections generally carry higher MUD rates because the underlying bonds are younger. It is one of the few costs that reliably falls over time as those bonds are paid down.
Insurance is the other Houston-specific line. Flood zone designation materially changes the premium, and it is parcel-level — being outside a mapped floodplain is not the same as your neighbours being outside it. Get a real quote on the specific address before you are under contract, not after.

Frequently Asked Questions
What is included in a Houston monthly mortgage payment?+
Principal, interest, property tax, homeowners insurance, and — in most Fort Bend County master-planned communities — HOA dues. Buyers putting less than 20% down also pay mortgage insurance. Property tax is the line that surprises people relocating to Texas: there is no state income tax, but effective property tax rates are among the highest in the country.
Why are Fort Bend County property taxes so high?+
Texas funds local services through property tax rather than income tax, and many Fort Bend County subdivisions sit inside a Municipal Utility District (MUD) that adds its own levy to fund water, sewer, and drainage infrastructure. A combined rate in the 2.5% to 3.5% range is common, and it varies by subdivision — two homes at the same price a mile apart can differ by hundreds of dollars a month.
Does this calculator include HOA dues?+
Yes. HOA dues are a separate input because they vary widely across Houston-area communities — from nothing in older unincorporated areas to several thousand dollars a year in amenity-heavy master-planned communities like Telfair, Riverstone, and Sienna.
How much do I need for a down payment in Houston?+
Conventional loans start at 3% down for qualifying buyers, FHA at 3.5%, and VA and USDA loans can require nothing down for eligible borrowers. Twenty percent avoids mortgage insurance but is not a requirement. Texas also offers first-time buyer and down payment assistance programs.
Is this estimate good enough to make an offer on?+
No. It is a planning tool. Actual payment depends on your credit profile, the lender, the specific tax rate for that parcel, and the insurance quote for that structure — flood zone matters in Houston. Get a written pre-approval from a licensed lender before making an offer.
