Mortgage basics for first-time buyers
Most U.S. mortgage payments include four core housing costs: principal, interest, property taxes, and homeowners insurance. If your down payment is below 20%, mortgage insurance may also apply. Understanding each cost line helps you build a more accurate home-buying budget.
Loan term matters too. A 30-year mortgage often keeps the monthly payment lower, but a 15-year mortgage can reduce lifetime interest. Rate changes, property taxes, HOA fees, and refinance costs all influence what a loan really costs over time.
Use the affordability calculator to estimate price range, then move to the mortgage calculator for detailed monthly estimates and amortization. If you already own a home, the refinance calculator and extra payment calculator can help you compare strategies.
