Does a 50-year mortgage really help Boston condo buyers?

• Significantly More Total Interest: Borrowers would pay a staggering amount more in total interest over the life of the loan. On a sample $360,000 loan, the total interest paid over 50 years (at a constant 6.25% rate) could be over $816,000, almost double the $438,000 paid on a 30-year loan.
• Slower Equity Building: Because more of the early payments go toward interest rather than the principal, building home equity would happen very slowly. After 10 years, a homeowner with a 50-year mortgage might only have a 14% equity stake, compared to a 24% stake with a 30-year loan (excluding home price appreciation). This increases the risk of being “underwater” (owing more than the home is worth) if market values drop.
• Higher Interest Rates: Lenders would likely charge a higher interest rate on 50-year mortgages than on 30-year loans because of the increased risk over a longer time horizon. This would further shrink the monthly payment savings and increase the total interest paid.
• Market Distortion: Introducing longer loan terms could increase buyer demand without addressing the fundamental problem of insufficient housing supply, potentially driving home prices even higher and negating any initial affordability benefit.
• Regulatory Hurdles: Currently, mortgages with terms over 30 years do not meet the definition of a “qualified mortgage” under the Dodd-Frank Act, meaning they are ineligible for purchase by government-sponsored enterprises like Fannie Mae and Freddie Mac. Without this crucial secondary market support, lenders would be hesitant to offer such products widely.
