Quick answer
With 20% down and a 6.5% 30-year mortgage, a $500,000 house needs about $134,247 in gross annual income. The estimated monthly housing cost is $3,132 before HOA dues or unusual local fees. That's about $26,849/year more than a $400,000 house needs. For context, the required income is about 1.8x the roughly $75,000 US median household income.
That monthly cost breaks down to roughly $2,528 in principal & interest on the $400,000 loan, plus about $458/month in estimated property tax and $146/month in estimated insurance.
