How much house can I afford in Houston, TX is a question about your monthly payment, not your purchase price. At an illustrative 6.5 percent on a 30-year fixed loan with 5 percent down, a $75,000 household income with no other debt supports roughly a $310,000 home here. Add a $600 monthly car and student loan payment and that number drops to about $244,000. Houston property taxes near 2.1 percent and Gulf Coast insurance take a larger share of the payment than they would almost anywhere else, so a national calculator will overstate your range. All figures are illustrative and subject to a full loan estimate.
How much house can I afford in Houston, TX is the first question almost every buyer asks me, and it is usually the one an online calculator answers worst. Those tools take your income, apply a generic ratio, and hand back a price. What they leave out is the part of the payment that is specific to this market: combined property tax rates that commonly run 2.0 to 2.6 percent of appraised value, homeowners insurance priced for wind and hail, mortgage insurance if you are putting less than 20 percent down, and in much of Katy, Cypress, and Fulshear a MUD assessment folded into the tax rate. In more than twenty years of Houston-area lending I have watched that gap send buyers shopping $60,000 above where they actually qualify. This guide runs the real math, with worked examples at $300,000 and $400,000.
How Much House Can I Afford in Houston, TX? Start With the Payment
Underwriting does not evaluate a purchase price. It evaluates a monthly payment against your monthly income. Everything else, including the price you can offer, falls out of that comparison. So the honest sequence is backwards from how most people shop: find the payment you qualify for, subtract the parts of it that are not loan, and only then convert what is left into a price.
That subtraction step is where Houston diverges from the national picture. Here is the same monthly budget, $3,178, run through two different markets at 5 percent down and an illustrative 6.5 percent rate.
| Market | Tax and insurance assumption | Price that $3,178 a month buys |
|---|---|---|
| Houston, TX | 2.1 percent taxes, Gulf Coast insurance | About $350,000 |
| A 1.0 percent tax market inland | 1.0 percent taxes, 0.5 percent insurance | About $415,000 |
Illustrative comparison at 5 percent down on a 30-year fixed loan, including estimated mortgage insurance. Not an offer or commitment to lend.
Same payment, about 19 percent less house. That is the number relocating buyers need to see before they start touring, and it is the reason I ask people to run a Houston-specific calculation rather than the one they used in their last city. Texas has no state income tax, which is the other half of the trade, but that shows up in your paycheck rather than in your qualifying ratio.
Want your actual number instead of an estimate?
Send me your income, your monthly debts, and the areas you are considering. I will run your ratios against real district tax rates and an insurance estimate and tell you the price range you can genuinely write an offer in. It is a short call and it costs you nothing.
The Two Ratios Lenders Actually Use
The answer to how much house can I afford in Houston, TX comes down to two debt-to-income ratios, both measured against gross monthly income before taxes.
The front-end ratio is your total housing payment divided by gross income. Housing payment means principal, interest, property taxes, homeowners insurance, mortgage insurance, HOA dues, and flood insurance where it applies. Not just principal and interest.
The back-end ratio is that same housing payment plus every other monthly obligation on your credit report: car loans, student loans, personal loans, minimum credit card payments, child support. Utilities, groceries, insurance on your car, and your 401(k) contribution do not count.
The old rule of thumb was 28 percent front-end and 36 percent back-end. That guidance is conservative by current standards and it is not what automated underwriting applies. In practice, conventional files approved through automated underwriting commonly run to a 45 percent back-end ratio and can reach 50 percent when reserves, credit, and residual income support it. FHA files run higher still in many cases. Guidelines vary by program, investor, and individual file, so treat these as the shape of the conversation rather than a promise.
The examples below use a 45 percent back-end ratio, because that reflects what a typical approval looks like rather than a rule from 1985. Qualifying at 45 percent and choosing to spend at 45 percent are two different decisions, and I will come back to that.
What a Houston Payment Contains That a National Calculator Misses
Before the worked examples, here is what goes into the payment side of the ratio, with the assumptions I am using throughout.
Principal and interest at an illustrative 6.5 percent on a 30-year fixed loan. Rates move daily and yours depends on credit, program, and the day you lock.
Property taxes at 2.1 percent of value, which sits in the middle of the Harris County range once you stack county, school district, city or ESD, community college, and any utility district. Each tenth of a percent is real money, and two otherwise identical houses in different districts can differ by $150 a month. My guide to MUD taxes in Houston covers the line item that surprises relocating buyers most.
Homeowners insurance at a Gulf Coast level, roughly $325 a month on a $350,000 home and scaled proportionally at other price points. Wind and hail coverage is why that figure is higher than the national average, and your quote depends on the roof, the age of the home, and claim history.
Mortgage insurance at roughly half a percent of the loan amount per year, which applies on conventional financing below 20 percent down and can be removed later as equity builds.
Flood insurance, HOA dues, and a MUD assessment sit on top of all of this where they apply, so treat every total below as a floor. Leave any of those four lines out and the answer to how much house can I afford in Houston, TX comes back too high. For the full picture on a home you already have in mind, see what it really costs to own a home in Houston.
How Much House Can I Afford in Houston, TX at $300,000 and $400,000?
Two worked examples, both at 5 percent down on a 30-year fixed loan at an illustrative 6.5 percent.
| Line item | $300,000 home | $400,000 home |
|---|---|---|
| Down payment at 5 percent | $15,000 | $20,000 |
| Loan amount | $285,000 | $380,000 |
| Principal and interest | $1,801 | $2,402 |
| Property taxes at 2.1 percent | $525 | $700 |
| Homeowners insurance | $278 | $371 |
| Mortgage insurance | $119 | $158 |
| Total monthly payment | About $2,725 | About $3,630 |
| Income needed, no other debt | About $73,000 | About $97,000 |
| Income needed with $600 of monthly debt | About $89,000 | About $113,000 |
Illustrative only. Assumes 5 percent down, a 30-year fixed loan at 6.5 percent, a 2.1 percent tax rate, estimated Gulf Coast insurance and mortgage insurance, and a 45 percent back-end debt-to-income ratio. Excludes MUD, flood insurance, and HOA dues. Subject to borrower qualification, credit approval, program availability, and a full loan estimate.
Notice the composition. On the $300,000 home, principal and interest are about $1,801 of a $2,725 payment. Roughly a third of what you send in every month has nothing to do with your interest rate. That is the ratio that breaks national calculators, and it is why two buyers with identical incomes qualify for very different prices in Houston than they would in Ohio.
Income Needed by Price Point in Houston, TX
The same math across the price points Houston buyers actually shop, using the assumptions above.
| Purchase price | Monthly payment | Income needed, no other debt | Income needed with $600 of debt |
|---|---|---|---|
| $250,000 | About $2,270 | About $61,000 | About $77,000 |
| $300,000 | About $2,725 | About $73,000 | About $89,000 |
| $350,000 (near the metro median) | About $3,178 | About $85,000 | About $101,000 |
| $400,000 | About $3,630 | About $97,000 | About $113,000 |
| $500,000 | About $4,539 | About $121,000 | About $137,000 |
Illustrative only, on the assumptions stated above. Your figures depend on credit, program, property, district tax rate, and insurance quote, and are subject to a full loan estimate.
The metro median sale price has been sitting near $350,000, which on these assumptions calls for something in the mid-eighties of household income with no other debt in the picture. That is above the county’s median household income, and it explains a lot about how this market actually works: many buyers shop below the median price, buy with a co-borrower, use down payment assistance to reduce the loan, or look toward Pearland and Katy where the same money reaches further. Harris County assistance programs layer with several of the state options.
How Much House Can I Afford in Houston, TX With Car and Student Loan Payments?
This is where most buyers lose room without realizing it, so it deserves its own number. Working the math in the other direction, here is what a given income supports at 5 percent down, with and without $600 a month of other obligations.
| Household income | Price with no other debt | Price with $600 monthly debt | Difference |
|---|---|---|---|
| $75,000 | About $310,000 | About $244,000 | $66,000 |
| $100,000 | About $413,000 | About $347,000 | $66,000 |
| $125,000 | About $516,000 | About $450,000 | $66,000 |
| $150,000 | About $620,000 | About $553,000 | $66,000 |
Illustrative only, on the assumptions stated above. Not an offer or commitment to lend.
The difference column is the same at every income, and that is the useful part. Under these assumptions, every $100 of monthly debt payment costs you roughly $11,000 of purchase price in Houston. A $550 car note is about $60,000 of house. Two car notes and a student loan can be more than $100,000.
That does not mean pay everything off before you buy. A credit card balance you can clear entirely is often worth clearing, because the minimum payment disappears with it. A car loan with four payments left may drop out of the ratio already, depending on the program. But a $30,000 auto loan you would have to pay off in full to remove is usually better left alone than drained from the money you need for a down payment and reserves. That trade is worth thinking through with actual numbers rather than instinct, and it is one of the more common conversations I have.
The Levers That Move Your Number
Four things move the answer to how much house can I afford in Houston, TX more than anything else, and three of them are inside your control.
Loan program. The program changes the mortgage insurance line and sometimes the ratio ceiling. FHA financing allows a smaller down payment and is often more forgiving on ratios, with a different mortgage insurance structure. VA financing can remove both the down payment and the monthly mortgage insurance entirely for eligible veterans, which changes affordability more than any other single factor. Fairway is not affiliated with any government agencies. These materials are not from HUD or FHA and were not approved by HUD or a government agency.
Down payment. More down lowers principal and interest and, past 20 percent, removes mortgage insurance. It also drains reserves, and reserves matter to underwriting and to your peace of mind. My guide to how much down payment you really need works through where that balance usually lands.
The district you buy in. Two houses at the same price in different tax districts can differ by $150 a month or more, which is $16,000 of purchase power. Always pull the actual rate for the specific address rather than a county average.
The homestead exemption. Filing on your primary residence reduces the school district portion of your taxable value and caps how fast that value can rise. It does not usually change your qualifying figure at application, since escrow is set on the seller’s current tax bill, but it changes what you actually pay going forward.
The conforming limit. Harris, Fort Bend, Montgomery, and Waller counties all share a 2026 conforming limit of $832,750 for a one-unit property. Above that you are in jumbo territory, where down payment and reserve expectations tighten. The 2026 FHA limit for a one-unit Houston-area property is $541,287, which is a real ceiling for buyers counting on FHA in the higher submarkets.
How Much House Can I Afford in Houston, TX? Five Steps to a Real Number
One, add up your gross monthly income. Why it matters: it is the denominator of both ratios. Include bonus, overtime, and commission only if you have the two-year history that lets a lender average it, or you will build your budget on income that will not count.
Two, pull your credit and total the minimum payments. Why it matters: the back-end ratio uses what your credit report says, not what you remember paying. Surprises here are common, and each $100 is roughly $11,000 of purchase price.
Three, price the taxes and insurance for a specific area. Why it matters: this is the step calculators skip, and in Houston it is worth tens of thousands of dollars of range. Get the district rate and an insurance quote before you settle on a number.
Four, decide your comfortable payment separately from your qualifying payment. Why it matters: qualifying at 45 percent does not mean you should spend there. Houston adds costs that never touch your mortgage statement, including maintenance on clay soil foundations and wind and hail deductibles that are often a percentage of dwelling coverage rather than a flat dollar amount. Plenty of my clients qualify for more than they choose to spend, and none of them have regretted it.
Five, get pre-approved before you tour. Why it matters: a pre-approval turns all of the above into a document a seller will take seriously. Start with pre-approval versus pre-qualification, gather the documents you will need to apply, and factor in Houston closing costs so the cash side does not surprise you. You can run scenarios yourself on my mortgage calculator, or begin your application online when you are ready. The broader Houston home loans guide covers the rest of the process.
Get Your Real Houston Number
Tables use averages. Your approval uses your file, and how much house can I afford in Houston, TX only has one answer that matters: yours. Give me your income, your monthly obligations, your available down payment, and the areas you are considering, and I will run the ratios against real district tax rates and an insurance estimate. You will leave the conversation with a price range you can actually write an offer in, which program fits, and what to fix first if the number is not where you want it. Twenty-plus years of Houston-area lending and an education-first approach stand behind that.
