Lenders start with your debt-to-income ratio, which compares your monthly debts to your gross income. Most conventional loan programs target a total DTI below a certain threshold, though FHA and VA loans allow more flexibility for qualified borrowers. Your credit score also plays a major role, since it affects both your approval odds and the pricing you receive. Beyond the mortgage payment itself, lenders factor in property taxes and insurance when sizing your loan. The result is a maximum purchase price that reflects your full financial picture, not just the loan amount you qualify for on paper.

Texas has no state income tax, but property taxes in DFW run well above the national average and deserve close attention. In counties across the metro, annual property tax bills can add a meaningful chunk to your monthly housing cost. Homeowners insurance has also climbed in recent years, particularly in areas prone to hail or severe storms. Many suburban neighborhoods carry HOA dues that cover landscaping and shared amenities. When you stack property taxes and insurance on top of principal and interest, the true cost of owning a home in DFW looks very different from the listing price alone.

A few practical steps can sharpen your budget before you start touring homes. Pull your credit reports and pay down any revolving balances in the months before applying. Save for both a down payment and closing costs, since most buyers underestimate how much cash they need at the table. Get pre-approved rather than pre-qualified, so you know exactly how much a lender is willing to let you borrow. Finally, build in a buffer for repairs and maintenance, plus room for rate adjustments if your loan has an adjustable component.
