Frequently Asked Questions
What is the monthly payment on a $500,000 home at 6.5%?
$3,484 per month for principal and interest on a 15-year fixed mortgage with 20% down ($400,000 loan). This doesn't include property tax, homeowners insurance, or HOA fees, which typically add $300–800/month.
How much total interest do I pay on this mortgage?
$227,197 in interest over 15 years. On a 15-year term at 6.5%, interest adds up significantly. Choosing a 15-year mortgage at a similar rate would roughly halve total interest paid, though monthly payments would be higher.
What salary do I need to afford a $500,000 home?
Using the 28% front-end rule, you'd need approximately $149,000/year in gross income. Lenders also check total debt-to-income (≤36% guideline), so existing car payments or student loans reduce your maximum home price.
Does 20% down make sense, or should I put more down?
20% down eliminates PMI — a good threshold. Putting more down reduces your monthly payment and total interest, but ties up cash that could be invested elsewhere.
