Houston Mortgage Calculator: What Will Your Monthly Payment Be?

Texas has no state minimum; the loan program sets it. Conventional loans generally want a 620 or better, FHA allows 580 with 3.5 percent down (500 to 579 with 10 percent down), and VA and USDA set no official floor, though most lenders look for the high 500s to low 600s. A higher score lowers both your rate and your mortgage insurance, so pulling your score a few months before you shop gives you time to fix errors or pay down balances.

Less than most buyers think. Conventional first-time buyer programs start at 3 percent down, FHA at 3.5 percent, and VA and USDA loans can be zero down for eligible buyers. Twenty percent avoids private mortgage insurance but is not required. Budget another 2 to 5 percent of the price for closing costs and prepaid taxes and insurance. In 2026 a conventional loan is "conforming" up to $832,750 and the FHA limit in Harris County is $541,287; above the conforming limit you are in jumbo territory with stricter rules. There are also 0 percent down programs in certain parts of town or with certain lenders if you qualify; ask us for details.

Yes, several. The Texas Department of Housing and Community Affairs runs My First Texas Home and My Choice Texas Home, which pair a 30-year loan with up to 5 percent of the loan amount in assistance. The Texas State Affordable Housing Corporation offers Home Sweet Texas and Homes for Texas Heroes grants and second liens, also up to 5 percent. The City of Houston's Homebuyer Assistance Program lists up to $125,000 for income-qualified buyers of homes inside the city, and Harris County runs its own program for unincorporated areas. Income limits, purchase price caps and funding change often, so confirm current terms with the program and a participating lender.

Inside the City of Houston the combined rate is about 2.1 percent of appraised value before exemptions; many suburbs run 2 to 2.5 percent, and newer subdivisions with a MUD can exceed 3 percent. Most lenders collect one twelfth of the annual bill each month in escrow and pay the county by January 31. A homestead exemption and a yearly protest both lower the bill, and your escrow payment adjusts after the county updates the value.

A municipal utility district is a special district that borrowed money to build a subdivision's water, sewer and drainage systems and repays it with its own property tax. They are common in Katy, Cypress, Spring, Pearland, Fulshear, League City and most newer master-planned communities. Rates run from about $0.25 to $1.40 per $100 of value, with new districts at the high end and mature districts that have paid down their bonds at the low end. Our calculator's MUD toggle adds 1 percentage point as a placeholder. Texas law requires the seller to give you a notice of the district's tax rate and bonded debt before you sign a contract, and the county appraisal district lists every taxing unit for the address.

Three ways. It removes $140,000 of value from school district taxes, many Harris County entities and the City of Houston take a further 20 percent off their portion, and once it is in place your appraised value can rise no more than 10 percent a year. Owners 65 or older or with a qualifying disability get an extra $60,000 off school taxes and a school tax ceiling. You can apply with the county appraisal district as soon as you move into the home as your primary residence; it is free and there is no reason to pay a service to file it. Your lender lowers the escrow once the county applies it. Example: on a $450,000 home at Houston's 2.2 percent combined rate, the tax bill is about $9,900 a year with no exemption. With a homestead the school district taxes $310,000 and the city and county entities tax $360,000, so the bill drops to roughly $7,450, a savings of about $2,450 a year, or about $200 a month in your escrow payment.

For a typical single-family home, $3,000 to $6,000 a year is common in 2026, above the Texas average of about $3,900, and older roofs, larger homes and coastal addresses cost more. Houston policies usually carry a separate wind and hail deductible of 1 to 2 percent of the dwelling coverage, so compare that deductible along with the premium. Get quotes during your option period, since the roof's age and condition drive much of the price and can affect which carriers will write the policy.

If the home sits in a FEMA special flood hazard area, such as zone A or AE, your lender will require it. Outside those zones it is optional, but a large share of Harvey's flooded homes were outside the mapped high-risk areas, so many Houston owners carry it anyway. Policies come from the National Flood Insurance Program or private insurers and cost from a few hundred dollars a year in lower-risk zones to several thousand in high-risk zones. Texas sellers must disclose known flooding and flood insurance claims on the seller's disclosure notice, and we point you in the right direction to review flood zones and maps for any home you consider.

Plan on 2 to 5 percent of the purchase price. That covers lender fees, the appraisal, the lender's title policy, a survey if a recent one is not available, recording fees, prepaid interest and the first deposits into your tax and insurance escrow. Texas has no transfer tax, title insurance rates are set by the state, and in Houston the seller customarily pays for the owner's title policy, although everything is negotiable. We can work on negotiating seller credits to help you offset closing expenses. Lenders want YOU to come up with the down payment, but the rest we can work on negotiating if needed. We'll help you evaluate the options.

At late-2026 rates, with 10 percent down and modest other debts, a $100,000 household income supports roughly a $250,000 to $320,000 purchase, which is a payment of about $2,300 to $3,000 a month including Houston taxes and insurance. A car payment or student loans pull that down; a larger down payment, a lower rate or a seller-paid buydown pushes it up. A lender's pre-approval, which checks your actual credit, income and debts, is the figure to shop with.

It depends on how long you will keep the loan. A permanent buydown costs about 1 percent of the loan per point and usually lowers the rate by roughly a quarter point, so it pays off if you stay past the break-even year. A 2-1 buydown lowers the rate by 2 points in year one and 1 point in year two, and sellers or builders often fund it. A straight seller credit toward closing costs keeps more cash in your pocket on day one. With rates above 7 percent we see all three in Houston negotiations, and the right pick depends on your plans and the lender's quote, so run the numbers with your lender before you choose. Example: on a $292,500 loan, which is a $325,000 home with 10 percent down, at 7.25 percent the principal and interest payment is about $1,995 a month. Paying one point costs about $2,925 and might lower the rate to 7 percent, saving roughly $49 a month, so the break-even is about five years. A 2-1 buydown on the same loan costs the seller about $6,900 and cuts the payment to roughly $1,615 in year one and $1,800 in year two before it returns to $1,995. Many buyers take a seller credit or a temporary buydown today and plan to refinance if rates come down, but nobody can promise that they will, so make sure the payment works at today's rate.

Yes. Houston sellers expect a pre-approval letter with every offer, and a pre-approval, unlike a quick pre-qualification, means the lender has verified your credit, income and assets. It usually takes a day or two, stays valid for 60 to 90 days, and lets you compare rate quotes from several lenders within a short window with a single credit inquiry. Texas also now requires a written agreement with your agent before showings, effective January 1, 2026, so talk to an agent and a lender at the same time.
