How much house can you afford in Fort Worth right now? Start with your gross monthly income, subtract your other debts, and fit the full payment, including taxes and insurance, inside a debt-to-income ratio you're comfortable with.
Online calculators will give you a number in seconds. The problem is that most of them assume a tax rate, an insurance cost, and a debt load that may have nothing to do with you. In Fort Worth, property taxes alone can change your payment by hundreds of dollars a month depending on where the house sits.
Here's how I'd work through it, step by step, using current rates and sourced numbers. You can plug in your own income and debts as you go.
Step 1: Know how lenders measure affordability
Lenders use your debt-to-income ratio, or DTI. The Consumer Financial Protection Bureau defines it as all of your monthly debt payments divided by your gross monthly income. That includes the new house payment plus car loans, student loans, minimum credit card payments, and similar debts.
How high can it go? For conventional loans, Fannie Mae's Selling Guide caps total DTI at 36% for manually underwritten loans, up to 45% with strong credit and reserves, and at 50% for loans run through its Desktop Underwriter system. FHA, VA, and USDA loans have their own rules.
Here's the catch: the maximum a lender will approve isn't the same as what feels comfortable every month. I'd treat the lender's number as a ceiling, not a target.
Step 2: Turn your income into a payment range
As a reference point, Census data compiled by Data USA puts Fort Worth's 2024 median household income at $79,507. That's about $6,626 a month before taxes. At different DTI levels, that income supports these total monthly debt payments:
| Total DTI | Monthly debt budget on $6,626 gross |
|---|---|
| 36% | About $2,385 |
| 43% | About $2,849 |
| 50% | About $3,313 |
Remember, those are totals. If you have a $450 car payment, subtract it before you figure out what's left for housing.
Step 3: Price the payment at today's rates
Freddie Mac's Primary Mortgage Market Survey showed the average 30-year fixed rate at 7.28% on October 1, 2026, compared with 6.34% a year earlier. At 7.28%, principal and interest alone look like this:
| Loan amount | Monthly principal and interest at 7.28% |
|---|---|
| $250,000 | About $1,711 |
| $300,000 | About $2,053 |
| $350,000 | About $2,395 |
| $400,000 | About $2,737 |
The same $300,000 loan at 6.34% would have been about $1,865. That gap of nearly $190 a month is why a budget from last year may not work today.
Step 4: Add property taxes, insurance, and HOA
This is where Fort Worth budgets usually go wrong. Taxes and insurance are often escrowed into your monthly payment, and they're a big piece of it.
For 2025, the City of Fort Worth and Fort Worth ISD rates combined come to $2.16258 per $100 of taxable value. Tarrant County and other taxing units add more on top of that. Your homestead exemption helps: Texas school districts exempt $140,000 of a homestead's value for 2025, with an extra $60,000 for owners who are 65 or older or disabled. That exemption applies to the school portion of your bill.
Homes outside Fort Worth city limits, or inside a MUD or PID, have different totals. Before you fall for a house, look up its actual rates. My post on how property taxes work in Tarrant County walks through how to estimate a bill.
Then add homeowners insurance (get a real quote, not a guess) and any HOA dues. Those three items together can easily add several hundred dollars to the principal and interest figures above.
Step 5: Plan the cash you need at closing
Your down payment affects your loan amount and whether you pay mortgage insurance. Closing costs come on top of that, along with the option fee and earnest money you'll put up when you go under contract. I break down the line items in Understanding Closing Costs When Buying in Fort Worth.
If cash is the hurdle, look into assistance. The Texas Department of Housing and Community Affairs offers programs with up to 5% in down payment and closing cost help for eligible buyers. I cover those in Texas First-Time Home Buyer Programs.
Step 6: Leave room for real life
DTI doesn't count groceries, gas, utilities, or the new fence the backyard needs. Before you settle on a price, I'd build a monthly budget that includes the full house payment and everything else you spend, then see what's left. Keep some reserves after closing, too. Houses tend to find their first repair quickly.
Step 7: Get pre-approved
Once you have a comfortable number, a pre-approval turns it into a real one. A lender verifies your income, assets, and credit, and tells you what you qualify for. Compare offers from several lenders, then shop for homes below your approval if that's where your budget feels right.

Frequently asked questions
What debt-to-income ratio do I need to buy a house?
For conventional loans, Fannie Mae allows up to 50% total DTI through its automated underwriting, and 36% to 45% for manually underwritten loans. Other loan types have their own limits. A lower ratio gives you more breathing room.
How much do property taxes add to a Fort Worth mortgage payment?
It depends on the home's value, exemptions, and location. For 2025, the City of Fort Worth and Fort Worth ISD rates combined are $2.16258 per $100 of value, before county and other units are added. Look up the specific property's rates before you make an offer.
Should I buy at the top of my pre-approval?
Usually not. Your approval is the most a lender will lend, not a recommendation. Build a full monthly budget first and pick a price that leaves room for savings and repairs.
