A new mortgage structure introduced by Better Home & Finance (BETR) in collaboration with Coinbase Global (COIN) allows homebuyers to use Bitcoin (BTC) or USDC stablecoins as collateral instead of cash for down payments. This innovative approach combines traditional lending with crypto-backed borrowing, enabling buyers to secure a standard 15- or 30-year mortgage while locking their crypto assets as collateral. However, this method leads to higher monthly payments. For instance, on a $500,000 home, a typical mortgage with a 10% down payment at 6% interest costs about $2,698 per month, while the crypto-backed option ranges from $2,998 to $3,496. Over time, these higher payments can accumulate to thousands more annually. Although borrowers may avoid selling their crypto to defer capital gains taxes, the overall financial benefits may be outweighed by increased mortgage costs. Additionally, only a limited number of Americans possess sufficient cryptocurrency to make this financing option feasible.
