How Lenders Calculate Your Maximum Mortgage
Mortgage qualification starts with two numbers: your gross monthly income and your debt-to-income ratio (DTI). Lenders use the back-end DTI, which includes all monthly debt payments (mortgage, car, student loans, credit cards, child support) divided by gross monthly income. Most conventional lenders cap DTI at 36-43%, while FHA allows up to 50% with compensating factors.
On an $85,000 salary, your gross monthly income is $7,083. At a 36% DTI, maximum total debt payments are $2,550/month. Subtract existing debts of $500/month, and your maximum housing payment is $2,050/month. At 6.75% over 30 years with 10% down, that supports a home price of approximately $330,000-$350,000. The exact amount varies with property tax rates, insurance costs, and whether PMI is required.
Why Your Down Payment Changes Everything
The down payment affects your maximum home price in three ways. First, a larger down payment means you need a smaller loan for the same home price, reducing your monthly payment and allowing you to qualify for a more expensive property. Second, putting 20% or more down eliminates PMI (private mortgage insurance), which saves $100-$300/month on a typical loan. That saved PMI amount can go toward a larger principal and interest payment, increasing your purchasing power by $20,000-$50,000. Third, a larger down payment demonstrates financial strength to lenders, potentially qualifying you for a better interest rate.
