How Lenders Calculate Affordability

Mortgage lenders use two DTI thresholds. The front-end ratio (or housing ratio) limits your monthly PITI payment to 28% of gross monthly income. The back-end ratio limits all monthly debt — housing plus car loans, student loans, and minimum credit card payments — to 36% of gross income. Your maximum loan is determined by whichever threshold is more restrictive.

FHA loans allow higher DTI ratios (up to 43–50%) but require mortgage insurance. Conventional lenders may approve up to 45% DTI with strong compensating factors like excellent credit or large cash reserves.

Frequently Asked Questions

How much house can I afford on a $75,000 salary?

At $75,000/year with a 20% down payment and 7% rate, you can typically afford a home around $280,000–$320,000, keeping your PITI payment under $1,750/month (28% of gross income). Monthly debts like car payments reduce this limit significantly.

What is the 28/36 rule for a mortgage?

The 28/36 rule: spend no more than 28% of gross monthly income on housing (PITI) and no more than 36% on all debt combined (housing + car loans + student loans + credit cards). Lenders use these thresholds to assess mortgage affordability.

What is DTI and why does it matter for a mortgage?

DTI (debt-to-income ratio) = total monthly debt payments ÷ gross monthly income. Most conventional lenders require a DTI under 43%; the best rates go to borrowers with DTI under 36%. A high DTI means you qualify for a smaller loan or higher rate.

How much should I put down on a house?

20% down avoids PMI and gives you the best rates. FHA loans require just 3.5% down (580+ credit score). Conventional loans allow 3–5% down with PMI. A larger down payment reduces your monthly payment and total interest paid over the loan term.
