AFFORDABILITY EXAMPLE

How much house can I afford on a $100,000 salary?

About $333,000 with no other debts, or $280,000 with $1,000/month in other debts, at 20% down and a 7.4% 30-year rate (Freddie Mac PMMS, as of 10/8/2026).

A $100,000 salary is $8,333 a month gross. At 28% for housing that is a $2,333 monthly budget for principal, interest, taxes and insurance, and the 36% total limit caps housing plus all debts at $3,000.

Rates, down payment and local taxes move this figure a lot; a state with higher property tax lowers the price you can afford.

GOOD QUESTIONS

A few things you
might be wondering.

What ratios does this use?

A 28% housing ratio and a 36% total debt ratio on gross income, the calculator defaults. The lower of the two limits the budget.

What is assumed besides income?

20% down, a 30-year loan at 7.4%, 0.9% property tax, $2,872/year insurance, no HOA. Cash for the down payment is not capped here.

Do lenders use the same limits?

Not necessarily. Lenders set their own ratio limits and credit rules; this is a planning estimate, not an approval.
