What Salary Do You Need to Buy a $400K House in DFW?

DFW homeowners with homes valued between $350,000 and $450,000 have a median household income of about $128,500, based on the 2024 American Community Survey. That's what people who already own at this price earn, not a cutoff. The salary you need to buy a $400K house in DFW depends on your debts, down payment and rate.

A $400,000 house is also about as typical as it gets here. The median value of an owner-occupied home in the Dallas-Fort Worth metro was $389,500 in the same survey, so this is the price point where a lot of buyers land.

How Do Lenders Decide What Salary You Need?

Lenders don't look at your salary on its own. They compare your monthly debts to your gross monthly income, your debt-to-income ratio, or DTI.

• The 28/36 guideline: your house payment stays at or under 28% of your gross monthly income, and all your monthly debts together stay at or under 36%. It's a conservative starting point, not a hard limit.
• Common loan limits: many loans look for a total DTI around 43%, and some programs allow up to 50% with strong credit or savings.

Your lender makes the final call based on your full file, so treat the numbers below as a way to get your bearings, not an approval.

What Does a $400,000 House Cost Per Month in DFW?

Here's one example. The rate is Freddie Mac's 30-year average of 6.76% for the week of September 10, 2026, and your rate will depend on your credit and loan type.

• Price and down payment: $400,000 with 10% down, a $360,000 loan
• Principal and interest: about $2,337 a month
• Property taxes: about $733 a month at a 2.2% combined rate, before any exemptions
• Homeowners insurance: about $350 a month
• Mortgage insurance: about $150 a month, figured at roughly 0.5% of the loan

That comes to about $3,570 a month, before HOA dues.

Two of those lines are bigger in Texas than most buyers expect. Combined property tax rates run about 2.0% to 2.6% in Dallas County and roughly 1.66% to 1.99% in Denton County, depending on the city and school district. Homeowners insurance averages about $4,212 a year in Dallas for $300,000 in dwelling coverage, because North Texas gets more hail than almost anywhere in the country.

What Salary Do You Need to Buy a $400K House in DFW?

Using that $3,570 payment, here's how the salary to buy a $400K house changes with the guideline and your other debts:

• At the 28% housing guideline: about $153,000 a year
• At 43% total DTI with no other debts: about $99,600 a year
• At 43% total DTI with $600 a month in car and student loan payments: about $116,400 a year

So the honest answer is a range. A household with no other debts might qualify closer to $100,000 with a lender that allows 43%, while a household that wants its payment to feel comfortable is closer to $150,000. The $128,500 median for DFW owners in this price range falls right between the two.

What Changes the Income You Need?

• Down payment. Put 20% down and the loan drops to $320,000, the mortgage insurance goes away, and the payment falls to about $3,160 a month. At the 28% guideline, that's about $135,500 a year instead of $153,000.
• Rate. On a $360,000 loan, a rate one point lower cuts principal and interest by about $234 a month.
• City and school district. The same $400,000 price can carry a very different tax bill a few miles apart, so compare the tax rate for the exact address.
• The homestead exemption. Once you move in, file for it with your appraisal district. It removes $140,000 of your home's value from school taxes and caps how much your taxable value can rise each year.
• Your other debts. Paying off a small card or car loan before you apply can raise what you qualify for more than you'd expect.
• Assistance programs. Texas programs through TSAHC and TDHCA can cover part of your down payment or closing costs if your income and the price fit their limits.

Should You Buy Right at the Top of Your Approval?

Usually not. An approval tells you what a lender thinks you can repay, not what leaves room for savings, repairs and the rest of your life. The first year in a house tends to bring the surprise costs, so a payment that sits comfortably below your maximum gives you room for them. I've told every client the same thing; when planning for a new home, plan for the payment, not the purchase price. Most people do the opposite, but the purchase can be a range of payments depending on several factors and you won't know what your actual payment is until you've fallen for a home. Allowing yourself to work backwards from payment to purchase price gives you specific criteria that you know you need to find, making your search even smoother.
