What Does a $400,000 Home Cost Per Month in Houston?

The parts of a monthly payment

Your monthly payment is not one number. It is a stack of costs, and each one moves for different reasons. The CFPB walks through what is included in a mortgage payment. Here is the short version:

Principal and interest

Principal is the part of the loan you pay down. Interest is the cost of borrowing the money. Together they are the core of the payment, and the interest portion is driven by your rate, which is set at application and changes with the market.

Property taxes

Property taxes are collected with your payment and held in escrow, then paid to the county each year. In Texas they are a big line, and they vary by county, city, and school district.

Homeowners insurance

Homeowners insurance protects the home and is also typically escrowed. In the Houston area it runs higher than in many parts of the country because of wind, hail, and flood risk. Flood insurance is separate and often required in flood zones.

HOA dues, where they apply

Homeowners association dues cover shared amenities and neighborhood upkeep. They vary widely by community, from a few hundred to a few thousand dollars a year, and they are not part of the loan payment itself. Some communities have them, some do not.

Why Texas property taxes matter

Texas has no state income tax, and local governments lean heavily on property taxes to fund schools, roads, and services. As a result, typical effective property tax rates in Texas are among the nation's highest. A common planning range is roughly 1.8% to 2.5% of the home's value per year, depending on the county and the exemptions you qualify for. That is a typical range to plan around, not a quote for any one property.

The exact rate depends on where the home sits, so the Harris County Appraisal District (or the appraisal district for the county the home is actually in) is the authoritative source for the tax rate and the exemptions that apply to your property. Your homestead exemption, if you qualify, can lower the taxable portion of the value.

Why Houston-area homeowners insurance runs high

The Houston area is exposed to wind, hail, and flood risk, and insurers price that risk into premiums. Homeowners insurance here typically costs more than in most of the country, and the exact premium depends on the home, its age and condition, the neighborhood, and the insurer.

Flood insurance is a separate policy. It is not part of a standard homeowners policy, and it is often required by lenders when the home is in a flood zone. You can check whether a property is in a flood zone on FEMA's flood maps, and the National Flood Insurance Program explains how flood coverage works. Even outside a mapped flood zone, many Houston-area buyers choose flood coverage anyway.

HOA dues vary widely by community

Many Houston-area neighborhoods, especially newer master-planned communities, have an HOA. Dues can range from a modest amount for basic upkeep to a few hundred dollars a month where the community maintains pools, parks, and gates. Some older neighborhoods have no HOA at all. The dues are set by the community, not by your lender, and they are disclosed before you close so there are no surprises.

A labeled example on a $400,000 home

Let's put the pieces together with one clearly labeled illustration. This is an example for planning, not a quote, and not an offer of credit. Every assumption is listed below so you can see exactly what is doing the work.

Location is the variable that moves the total

A home with a Katy or other suburban mailing address is not automatically inside Houston city limits. Property taxes, insurance, and HOA costs vary by the exact location, the county, the school district, and the community. Two homes at the same price can have meaningfully different monthly totals a few miles apart. That is why the real number for you comes from looking at the specific property, not from a headline figure.

Key takeaways

• The monthly cost is principal, interest, property taxes, homeowners insurance, and HOA dues where they apply. Principal and interest are only part of the picture.
• Texas property taxes are among the highest in the country, typically around 1.8% to 2.5% of value depending on county and exemptions.
• Houston-area homeowners insurance runs high due to wind, hail, and flood risk, and flood insurance is separate and often required in flood zones.
• The exact number depends on the specific property, county, exemptions, and community. A suburban address is not automatically inside Houston city limits.

Frequently asked questions

What is the biggest surprise in a Houston-area monthly payment?

For most buyers it is property taxes and insurance. Together they can add a thousand dollars or more a month on top of principal and interest, which is a much bigger share of the payment than in many other parts of the country.

Does a 20% down payment avoid mortgage insurance?

On a conventional loan, 20% down usually avoids private mortgage insurance. In this example, 20% down on $400,000 is $80,000, leaving a $320,000 loan with no mortgage insurance in the illustration. A smaller down payment is possible on many programs, but it changes the payment and often adds mortgage insurance.

How do I get the real number for a specific home?
