What This Means
For a $200,000 home with 20% down, you borrow $160,000. At 6.875%, a 50-year mortgage drops your monthly principal and interest payment to $947, compared to $1,051 on a 30-year and $1,427 on a 15-year. The monthly savings of $104 versus a 30-year term may sound appealing, but the true cost is significant: you pay $408,453 in total interest over 50 years versus $218,391 over 30 years — an extra $190,062. 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.
