Income needed to afford a $300,000 home
Can you afford a $300,000 house?
A $300,000 home at today’s 6.95% average rate requires $1,589/month in principal and interest with 20% down ($60,000). That translates to needing roughly $86K in gross annual income to stay within the conventional 28% housing expense ratio.
The difference between 5% and 20% down on a $300,000 home is significant: a 5% down payment ($15,000) adds PMI of about $202/month until you reach 20% equity, and adds $62,280 in total interest over the life of the loan. If you can afford the larger down payment, the math strongly favors it.
On a 15-year loan, the monthly P&I payment jumps to $2,150 — $561 more per month than the 30-year option — but you save $185,040 in total interest and own the home outright in half the time.
