How this is calculated
We use the standard fixed-rate amortization formula: M = P·r / (1 − (1+r)^−n), where P is the loan amount, r your monthly interest rate and n the number of payments. Property taxes, insurance and HOA fees vary by property, so they're not included — check any listing's payment tab for a full estimate.
