Income needed
To keep the $2,567.30 monthly housing cost at 28% of gross income, you'd need about $110,027 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 21 years 4 months, more of each payment goes to interest than to principal. From payment 257 on, principal takes the larger share.
