A mortgage payment has two parts: principal and interest, which depend on the price, your down payment and the rate a lender offers you; and the costs on top — property taxes, homeowners insurance (and flood insurance near the water), HOA dues where there's an association, and mortgage insurance if you put less than 20% down. Each home's page has a calculator that uses the rate you've been quoted and that home's own taxes and HOA dues from the listing. For your actual rate and Annual Percentage Rate (APR), ask a licensed lender — we can introduce you to Joey Milam at Alpha Mortgage Advantage, or you're free to choose any lender.
