What income does a $400,000 mortgage require?
Assume a 20% down payment, so the loan of $400,000 buys a home priced near $500,000 with $100,000 down. Add an estimated 1.3% of home value a year for property tax and insurance (about $542 a month; real costs vary by location). The total housing payment is then about $3,070 a month. Under the common 28% guideline for housing costs, that points to a gross income near $131,569 a year, before considering your other debts. See the $80,000 salary example for the full method.
Where your first payments go
At 6.5% over 30 years, interest in the first year is about $25,868 while the balance falls only from $400,000 to about $395,529. After 5 years, the balance is about $374,444, so you have repaid about $25,556 of principal while paying about $126,140 in interest. Early payments are mostly interest, which is why extra principal early on saves so much.
