Choose a 30-year term for a lower monthly payment. Best if you want budget flexibility and plan to invest the savings elsewhere.
30-Year FixedChoose a 15 or 20-year term to pay significantly less total interest. You'll build equity faster but have a higher monthly payment.
15 or 20-YearA 25-year term splits the difference: slightly higher payment than 30-year, but thousands less in total interest. Often overlooked but powerful.
