Frequently asked questions

How is a mortgage payment calculated?
Monthly payment = P × [r(1+r)^n] / [(1+r)^n - 1], where P = loan principal, r = monthly interest rate, n = number of payments.
What is a good mortgage interest rate?
Rates vary by economy and credit score. In the US, a rate within 0.5% of the national average is generally considered competitive. Check current Freddie Mac weekly surveys for benchmarks.
How much house can I afford?
A common guideline is that your monthly housing costs should not exceed 28% of gross monthly income (front-end ratio), and total debt payments should stay below 36–43% (back-end DTI ratio).
What is an amortization schedule?
An amortization schedule shows every monthly payment broken into interest and principal, plus the remaining balance. In early years, most of each payment goes to interest; over time, more goes to principal.
