FAQ
What is the monthly payment on a $400,000 mortgage at 8.50% for 15 years?
Principal and interest alone is $3,939 per month. Adding the U.S. average property tax (1.1% of home value) and homeowners insurance ($2,200/year) brings the realistic monthly housing cost to about $4,581 on a $500,000 home with 20% down.
How much interest will I pay on a $400,000 loan at 8.50%?
You will pay about $309,012 in interest over 15 years, on top of the $400,000 principal. Choosing a 15-year term instead cuts total interest to roughly $309,012 but raises the monthly payment.
What salary do I need for a $400,000 mortgage?
Using the 28% rule (housing costs no more than 28% of gross income), a $4,581 monthly payment points to an income of around $196,000 per year, assuming no other debt. Lenders also apply the 36% back-end ratio that includes car loans, student loans and credit cards.
Does a $400,000 loan need PMI?
With 20% down the loan-to-value ratio is 80%, so no private mortgage insurance is required on this scenario.
