Income needed

To keep the $3,277.95 monthly housing cost at 28% of gross income, you'd need about $140,484 a year. Lenders also cap total debt payments near 36% of income, so car and student loan payments reduce what you can borrow.

Amortization schedule

For the first 20 years 9 months, more of each payment goes to interest than to principal. From payment 250 on, principal takes the larger share.
