Quick answer
With 20% down and a 6.5% 30-year mortgage, a $900,000 house needs about $241,645 in gross annual income. The estimated monthly housing cost is $5,638 before HOA dues or unusual local fees. That's about $40,274/year more than a $750,000 house needs. For context, the required income is about 3.2x the roughly $75,000 US median household income.
That monthly cost breaks down to roughly $4,551 in principal & interest on the $720,000 loan, plus about $825/month in estimated property tax and $262/month in estimated insurance.
