Income needed to afford a $700,000 home
Can you afford a $700,000 house?
A $700,000 home at today’s 6.95% average rate requires $3,707/month in principal and interest with 20% down ($140,000). That translates to needing roughly $201K in gross annual income to stay within the conventional 28% housing expense ratio.
The difference between 5% and 20% down on a $700,000 home is significant: a 5% down payment ($35,000) adds PMI of about $471/month until you reach 20% equity, and adds $145,200 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 $5,018 — $1,311 more per month than the 30-year option — but you save $431,280 in total interest and own the home outright in half the time.
