"How much house can I afford?" has two answers: the amount a lender will approve, and the monthly payment you'll actually be comfortable with. The smartest buyers care about both. Here's how it works in the Tri-Cities.
What lenders actually look at
Your budget comes down to four things:
- Income. Stable, documentable income — not just what you make, but what can be verified.
- Debts. Lenders compare your monthly debts to your income (your debt-to-income ratio, or DTI). A common guideline is keeping total housing and debt payments within roughly the high-30s to mid-40s percent of gross income, but many programs allow more depending on your full picture.
- Credit. Your score affects which programs and rates you qualify for. See what credit score you need to buy a house if you're not sure where you stand.
- Down payment. How much cash you bring — though with VA and USDA loans, eligible buyers can put zero down.
The payment is more than principal and interest
Your real monthly cost includes property taxes, homeowner's insurance, mortgage insurance (if your program requires it), and any HOA dues — plus a cushion for maintenance. A payment that looks affordable on a basic calculator can be several hundred dollars higher once everything's in. My payment estimator breaks all of that out so there are no surprises.
The Tri-Cities advantage
Compared with much of the country, East Tennessee remains relatively affordable, which means your income often stretches into a real home here. The right loan program can stretch it further: zero-down options keep your savings in your pocket for moving costs and repairs instead of a down payment.
The only number that really counts
Online calculators give you a ballpark. A pre-approval gives you your real, lender-backed budget — the number that lets you shop with confidence and write offers sellers take seriously. It costs nothing and isn't a commitment. Run the estimator for a rough idea, then let's get you a real number.
