Frequently asked questions
What is the 28/36 rule?
Spend no more than 28% of gross monthly income on housing (principal, interest, taxes, insurance and mortgage insurance) and no more than 36% on all debts combined. It is a conservative guideline, not a lender maximum.
What debt-to-income ratio do lenders allow?
Fannie Mae allows up to 36% total DTI on manually underwritten loans, up to 45% with strong credit and reserves, and up to 50% through Desktop Underwriter. FHA's standard manual limits are 31% housing and 43% total.
How much house can I afford with a $100K salary?
About $337,902 with 20% down under the 28/36 rule, $298,212 with an FHA loan and 3.5% down, or up to about $558,838 at a 45% debt-to-income ratio, at a 7.32% rate with no other debts.
Does the calculator include property taxes and insurance?
Yes. It assumes 1.1% of the price a year in property tax and $2,000 a year for insurance unless you change them, because both count toward your debt-to-income ratio.
What rate does the calculator use?
It starts with this week's Freddie Mac average 30-year fixed rate, 7.32% for the week of October 22, 2026. Replace it with the rate on your own quote.
