How Much House Can You Actually Afford?

Pre-approval tells you what lenders will give you, not what you should spend. Use these guidelines:

Rule Monthly Housing Cost Why
Lender’s max (43% DTI) Up to 43% of gross income What you qualify for
Conservative (28% rule) 28% of gross income Leaves room for saving and lifestyle
Comfortable (25% rule) 25% of take-home pay Accounts for taxes, insurance, maintenance

Pre-Approved Amount vs. Comfortable Amount

Gross Income Pre-Approved for (43% DTI) Comfortable (25% take-home) Difference
$75,000 $330,000 $245,000 $85,000
$100,000 $440,000 $330,000 $110,000
$125,000 $550,000 $410,000 $140,000
$150,000 $660,000 $490,000 $170,000
