🏠 Houston Mortgage Calculator

Use our Houston mortgage calculator to estimate monthly payments in America’s fourth-largest city. Houston offers a median home price of approximately $325,000 and no state income tax, but buyers face higher property tax rates averaging 1.80% and potential MUD (Municipal Utility District) taxes that can add significantly to your monthly payment. Houston is also the only major US city with no zoning ordinances, which affects property values and neighborhood character in unique ways. Flood insurance is an essential consideration given the region’s hurricane and heavy rainfall exposure. Enter your loan details below to see a complete breakdown including estimated taxes and insurance for Houston-area properties.

Houston Housing Market Overview

Houston’s sprawling metro area offers exceptional value compared to coastal markets, with a median home price around $325,000. The market spans an enormous geographic area across Harris, Fort Bend, Montgomery, and Brazoria counties. Inner-loop neighborhoods like the Heights, Montrose, and River Oaks range from $600,000 to well over $2,000,000. Midtown and EaDo (East Downtown) offer condos and townhomes from $250,000 to $500,000.

Suburban communities like Katy, Sugar Land, and The Woodlands provide family-friendly neighborhoods with newer construction and highly rated school districts, typically priced between $300,000 and $550,000. More affordable options exist in Cypress, Pearland, and Spring, with homes available from $250,000. Houston’s lack of zoning means land use can be unpredictable — a commercial establishment or multi-family development can be built adjacent to single-family residential properties without the buffer zones and use restrictions common in other cities.

Property Taxes and Local Costs

Texas has no state income tax, but property taxes are among the highest in the nation. Harris County’s effective property tax rate averages approximately 1.80%, though the total rate depends on which taxing entities your property falls under:

  • Harris County base rate: Approximately 0.35%–0.40%
  • City of Houston: Approximately 0.52%
  • School district: 0.90%–1.20% depending on the ISD
  • MUD taxes: Municipal Utility Districts add 0.20%–1.00% in many suburban developments, potentially pushing total rates above 2.50%
  • Homestead exemption: Texas offers a mandatory $100,000 school district exemption plus additional exemptions from other taxing entities

On a $325,000 home at a 1.80% effective rate, annual property taxes would be approximately $5,850. With MUD taxes, this could reach $7,500–$8,000 or more. Use our Percentage Calculator to estimate your specific tax burden.

Insurance and Special Considerations

Flood risk is the defining insurance consideration in Houston. The city experienced catastrophic flooding during Hurricane Harvey in 2017, and many areas remain vulnerable to both tropical storms and heavy rainfall events. Insurance costs include:

  • Homeowners insurance: $2,000–$4,500 per year, higher than the national average due to storm risk
  • Flood insurance: $800–$5,000 per year depending on flood zone designation. Even properties outside FEMA flood zones should consider coverage, as approximately 50% of Harvey flooding occurred outside mapped flood zones
  • Windstorm and hail coverage: Typically included in standard policies for the Houston metro, unlike the Texas coast where it requires separate coverage through TWIA

First-Time Buyer Resources in Houston

  • TDHCA My First Texas Home: The Texas Department of Housing and Community Affairs offers below-market rate mortgages with up to 5% in down payment and closing cost assistance for first-time buyers.
  • Houston Housing Authority Homebuyer Program: Provides down payment assistance and homebuyer education for income-eligible families in the City of Houston.

Tips for Houston Homebuyers

Always check flood zone maps and the property’s flooding history before making an offer. Ask whether the home flooded during Hurricane Harvey or Tropical Storm Imelda — Texas sellers are required to disclose known flooding events. Investigate MUD taxes thoroughly — newer suburban developments often fall within MUDs that can add $2,000–$5,000 or more to your annual tax bill beyond the base property tax.

Since Houston lacks zoning, research the surrounding area and any planned developments that could affect your property’s value. Deed restrictions in your subdivision provide some land-use protections, but verify they are current and enforceable. Get multiple insurance quotes and consider elevation certificates for properties in or near flood-risk areas. An elevation certificate that shows your home sits above the base flood elevation can dramatically reduce flood insurance premiums. The savings from Texas’s lack of income tax can offset the higher property tax burden, but only if you budget for the full tax and insurance picture.

Frequently Asked Questions

What are MUD taxes in Houston?
Municipal Utility Districts (MUDs) are special taxing entities that finance water, sewer, drainage, and road infrastructure in newer suburban developments. MUD tax rates range from 0.20% to 1.00% of assessed value, potentially adding $1,000–$5,000+ per year to your property tax bill on top of county, city, and school district taxes.
Do I need flood insurance in Houston?
Flood insurance is strongly recommended for all Houston properties, even those outside FEMA-designated flood zones. During Hurricane Harvey, approximately 50% of flooding occurred outside mapped flood zones. If your property is in a FEMA Special Flood Hazard Area and you have a federally backed mortgage, flood insurance is required. Premiums range from $800 to $5,000 per year.
How does Houston's lack of zoning affect homebuyers?
Houston is the only major US city without zoning ordinances, meaning there are fewer restrictions on how land can be used. A commercial business or multi-family development could be built near your single-family home. Deed restrictions in subdivisions provide some protection, but they expire and may not be renewed. Always research the surrounding area and planned developments before purchasing.
What is the property tax rate in Houston?
The effective property tax rate in Harris County averages approximately 1.80%, with total rates varying by location and taxing districts. County, city, school district, and MUD taxes combine to create your total rate. Texas’s $100,000 homestead exemption for school taxes provides meaningful relief, saving roughly $1,000–$1,400 per year.
Is Houston affordable for first-time buyers?
Yes, Houston is one of the most affordable major US cities for homebuyers. The $325,000 median price, combined with no state income tax and various down payment assistance programs (up to 5% through TDHCA and SETH), makes homeownership accessible. However, budget carefully for property taxes and insurance, which can add $800–$1,200 per month to your housing costs.
