What a $300,000 Mortgage Costs

At today's typical 7% rate on a 30-year fixed mortgage, a $300,000 loan runs roughly $1,996/month in principal and interest. Over 30 years you will pay back roughly $718,527 in total — that is the $300,000 principal plus about $418,527 in interest. Switching to a 15-year term cuts the interest dramatically but raises the monthly payment by roughly 50%.

Income You Need to Afford $300,000

Using the standard 28/36 rule (housing should be at most 28% of gross monthly income, total debt at most 36%), and assuming a 7% mortgage with property tax and insurance adding ~$400/month, you would typically need a gross household income of around $102,682/year to qualify for this loan. Lenders may go higher with strong credit and low other debts.
