Assumes equal monthly payments on a fully amortizing fixed-rate loan; no adjustable rates, interest-only periods or balloon payments. Excludes closing costs, utilities, maintenance, special assessments and other unentered costs. Actual payments and escrow can differ. Review a Loan Estimate with your lender.
