The honest answer is a range, not a single salary. Lenders look at the payment, your other debts, and your gross income. A how much house can I afford calculator is the right tool; this article shows the arithmetic so the result is not a mystery.

Start from the payment, not the price

A $300,000 home with 20% down at 7% for 30 years is about $1,597 per month of principal and interest — the example we use in community posts. Add 1.2% property tax ($300) and 0.35% insurance ($88) and educational PITI is about $1,985. With 5% down, add PMI and a larger loan.

Apply 28% and 36%

The 28% front-end guideline says housing (PITI + HOA) should stay near 28% of gross monthly income. $1,985 / 0.28 ≈ $7,089 a month, or about $85,000 a year, if you have almost no other debt and you use this tax/insurance example.

If your car and student loans already eat 10% of income, the 36% back-end cap is the tighter constraint. $1,985 plus $600 of other debts is $2,585, and $2,585 / 0.36 ≈ $7,181 a month — still around $86,000. If other debts are $1,200, required income jumps.

FHA programs often allow higher ratios. That does not make the payment smaller. It only means the underwriter may say yes while your budget says no. First-time buyers who max the ratio have no room for repairs.

Worked example

Price $300,000, down $60,000, rate 7%, 30-year conventional, tax 1.2%, insurance 0.35%, other debts $400. PITI ≈ $1,985. Housing ratio at $72,000 salary ($6,000/month) is 33% — above 28%, maybe acceptable to some conventional automated underwrites with strong credit, tight for comfort. At $90,000 ($7,500/month) the ratio is 26%. Run your debts in the affordability calculator rather than copying a blog salary.

Educational only. A lender uses your credit, actual tax bill, and the rate they can lock.

Often roughly $70,000–$90,000 gross for a 20% down 7% 30-year payment with moderate taxes and low other debts. Your DTI can move that a lot.
Lenders usually need a two-year history of overtime or bonus. Do not count a one-time spike.
