Stretching payments over five decades lowers monthly costs by a few hundred dollars, but the trade-offs are steep:
- A $500,000 loan at 6.1% would rack up $1.1 million in interest — more than double the home price.
- Even at a historically low 4% rate, borrowers would still pay $657K in interest, and equity would crawl — just 4% of the principal repaid after 10 years.
- Homeowners risk staying underwater far longer if prices dip.
The bottom line: a 50-year mortgage may sound like relief, but it could trap borrowers in half a century of debt and delay wealth-building for an entire generation.
