Banker's Take on 8.0%
This rate means you'll pay more in interest than the home is worth. Make sure the buy still makes sense for your situation. At 8.0%, your monthly payment on a $750K home is $4,403. Over 30 years, you'll pay the bank $985,080 in interest alone — 164% of what you borrowed.
To qualify, most lenders want your total monthly debt (including this payment) to stay under 43% of your gross monthly income. That means earning at least $189K/year with no other significant debt.

The part almost nobody publishes free
Prices and rates are widely reported. Whether a lender says yes is not. In the complete 2025 federal record, denial rates across the 100 largest FHA lenders ran from 1.8% to 78.7% — same programme, same year.
And it is not simply who applies where: standardizing on state, loan amount, income, debt-to-income and loan-to-value, applicant mix explains only a 2.7× range in expected outcomes.
