What This Means
For a $250,000 home with 20% down, you borrow $200,000. At 6.875%, a 50-year mortgage drops your monthly principal and interest payment to $1,184, compared to $1,314 on a 30-year and $1,784 on a 15-year. The monthly savings of $130 versus a 30-year term may sound appealing, but the true cost is significant: you pay $510,566 in total interest over 50 years versus $272,989 over 30 years — an extra $237,577. Your equity also builds far more slowly, with most of your early payments going toward interest. A 50-year mortgage can make sense as a temporary affordability tool if you plan to refinance or sell within a few years, but as a long-term strategy it costs substantially more than a conventional 30-year loan.
