Setting a Realistic Budget
Anchor your search to a payment you can live with, not a purchase price a lender approves.
Most first-time buyers reverse-engineer the wrong number. They ask, 'What's the biggest home I can qualify for?' The better question: 'What's the monthly payment I want to live with for the next 5–7 years?' Lenders use debt-to-income (DTI) ratios to determine your maximum. Comfort is a different calculation - one that includes childcare, retirement contributions, travel, and the buffer you need to sleep at night.
A working rule of thumb: your total housing payment (principal, interest, taxes, insurance, HOA, and PMI if any) should sit at or below 28% of gross monthly income when you want breathing room, and no higher than about 36% if you're stretching. Anything above 40% is legally possible on some programs but tends to compress the rest of your life.
The Four Numbers That Decide Your Budget
- Gross monthly income - pre-tax, all borrowers combined
- Existing monthly debt - car, student, credit card minimums, child support
- Cash available for down payment plus closing costs plus reserves
- Target housing payment - the ceiling you actually want to hit
- Gross monthly income
- $7,083
- 28% comfort ceiling (PITI)
- $1,983/mo
- 36% stretch ceiling (PITI + debts)
- $2,550/mo
- Existing car + student debt
- $525/mo
- Max housing payment at 36% stretch
- $2,025/mo
Payment estimate - actual qualification depends on credit, program, and underwriting.
