Quick answer
With 20% down and a 6.5% 30-year mortgage, a $750,000 house needs about $201,371 in gross annual income. The estimated monthly housing cost is $4,699 before HOA dues or unusual local fees. That's about $40,274/year more than a $600,000 house needs. For context, the required income is about 2.7x the roughly $75,000 US median household income.
That monthly cost breaks down to roughly $3,792 in principal & interest on the $600,000 loan, plus about $688/month in estimated property tax and $219/month in estimated insurance.
