What this calculator does
This calculator estimates the highest home price you can support in Dallas using the two debt-to-income limits lenders commonly use: housing costs as a share of gross income (front-end) and all debts as a share of gross income (back-end). Unlike a basic affordability tool, it includes Dallas's property tax, home insurance and HOA or condo fees, which change the answer a lot from city to city.
Dallas home prices sit above Houston's but well below coastal cities. Uptown, Oak Lawn, Bishop Arts, Lakewood, Lake Highlands and Preston Hollow each have their own price range, and many buyers look to suburbs such as Richardson, Plano and Garland for more space.
How to use it
- Enter gross income for everyone on the loan and your monthly debt payments.
- Enter the cash you have for a down payment.
- Set the mortgage rate and term.
- Adjust the 28% / 36% limits if your lender uses different ratios (some programs allow up to 43% or more on the back end).
- Check the local property tax, insurance and HOA defaults and replace them with numbers from listings.
The formula
Maximum housing payment = the lower of (income ÷ 12 × front-end %) and (income ÷ 12 × back-end % − other debts). The price is solved so that principal and interest on (price − down payment), plus property tax and insurance as a percentage of price, plus HOA dues, equals that payment.
Worked example for Dallas
Household income $115,000, $400 of other debts, default down payment and local costs:
| Item | Monthly |
|---|---|
| Gross monthly income | $9,583 |
| Existing debt payments | -$400 |
| Principal and interest | $1,767 |
| Property tax at 2% a year | $529 |
| Home insurance at 1.2% a year | $318 |
| HOA / condo fees | $70 |
| Total housing payment | $2,683 |
Estimated maximum home price: $317,504. Loan of $279,504 with $38,000 down; total housing payment $2,683 a month.
What limits buying power in Dallas
A Dallas home in Dallas ISD is taxed by Dallas ISD, the City of Dallas, Dallas County, Parkland Hospital and Dallas College, for about $2.22 per $100 in 2025 before exemptions — a bit higher than Houston. The school district's $140,000 homestead exemption is the largest saving, and the City, County and Parkland each take 20% off for homesteads.
Insurance can also swing the payment; get a quote before you commit to a price range.
Common mistakes and tips
- Using take-home pay instead of gross income — lenders use gross.
- Leaving out HOA or condo fees, which count just like property tax.
- Emptying savings for the down payment — lenders and co-op boards often want reserves.
- Assuming the maximum is comfortable; a price below it leaves room for repairs and rate changes.
- Forgetting PMI when putting down less than 20% on a conventional loan.
Frequently asked questions
How much house can I afford in Dallas?
With the default inputs on this page, the estimate is $317,504. Your result depends mostly on income, debts, down payment and the mortgage rate.
What is the 28/36 rule?
A common guideline: housing costs up to 28% of gross income and total debt payments up to 36%. Many loan programs allow higher ratios with strong credit or reserves.
Why does property tax matter so much in Dallas?
Property tax is paid every month through escrow, so a higher rate leaves less room for the loan itself. Dallas's effective rate is set in the defaults and explained in the property tax calculator.
Does this replace a lender pre-approval?
No. A lender reviews credit, income documents and the specific loan program. Use this estimate to plan before talking to lenders.
