A married couple from Ann Arbor, Michigan just bought their first home using Bitcoin as collateral — without selling a single coin. On June 4, mortgage lender Better Home & Finance and Coinbase announced the closing of the first Fannie Mae-backed loan secured by cryptocurrency. No Bitcoin sold, no capital gains tax triggered.
The product stacks two loans. Buyers get a standard 15- or 30-year conforming mortgage guaranteed by Fannie Mae, alongside a second lien backed by Bitcoin or USDC held in Coinbase custody. The collateral ratio is deliberately conservative: a $100,000 down payment requires pledging roughly $250,000 in Bitcoin. That buffer protects the lender from price swings while leaving the borrower's position fully intact.
For crypto holders, that detail matters enormously. Selling Bitcoin to fund a down payment triggers a taxable event — for large positions, the capital gains bill can run from 20% to 40% of profit before a buyer ever reaches the closing table. This structure lets them tap their crypto wealth without triggering that tax, preserving both the deferral and any future upside.
The policy change that made this possible happened earlier this year. Federal Housing Finance Agency director Bill Pulte directed mortgage regulators to recognize crypto held on licensed exchanges as an eligible asset in borrower assessments. Without that directive, Fannie Mae couldn't have guaranteed the loan. The product wouldn't exist.
Coinbase's Mark Troianovski put the market plainly: "Tens of millions of Americans have built real wealth in digital assets." Many of them clear the income and credit hurdles for a mortgage but don't have the liquid cash savings for a down payment. Traditional underwriting had no way to see their wealth — now it does.
For now, only Bitcoin and USDC qualify as collateral. Nationwide availability is expected by summer 2026. Additional assets may come later, though neither company has committed to a timeline. The bigger shift is already done: a government-backed agency that underwrites most American home loans now formally treats Bitcoin as a legitimate mortgage asset.
