You’ll need to apply for mortgage preapproval to get an estimated loan amount you could qualify for. Lenders use the preapproval process to review your overall financial picture — including your assets, credit history, debt and income — to calculate how much they’d be willing to lend you for a mortgage.
You can use the loan amount printed on your preapproval letter as a guide for your house hunting journey. But, be careful not to stretch your budget too thin and borrow to the maximum. That's because your preapproval amount doesn’t factor in recurring bills that aren’t regularly reported to the credit bureaus — including gas, cellphones and other utilities — so you’ll need to retain enough disposable income to comfortably cover these monthly bills, plus your new mortgage payment.
