Michigan Couple Closes First Fannie Mae-Backed Bitcoin Mortgage

A Michigan couple has closed the first Fannie Mae-backed mortgage in the United States using Bitcoin as collateral, giving crypto-backed home finance one of its clearest tests inside the conventional mortgage market.

The loan was completed for Joe and Amy, a married couple in their early 30s from Ann Arbor, Michigan. Better Home & Finance and Coinbase funded the transaction after introducing a token-backed mortgage structure designed for borrowers whose savings are held partly in digital assets rather than traditional cash accounts.

The closing turns the earlier Better-Coinbase mortgage plan into a completed home purchase. CryptoAdventure’s prior coverage of the Bitcoin-backed mortgage outlined how the product keeps the main home loan inside a conforming mortgage structure while using crypto collateral to help fund the down payment.

Better and Coinbase plan to make the product available to qualified borrowers nationwide by summer 2026. The initial collateral assets are Bitcoin and USDC, with the companies leaving room to add more digital assets as the product matures.

How The Crypto Collateral Structure Works

The product does not mean a buyer pays for a home directly with Bitcoin. Borrowers receive two loans at closing through Better Mortgage.

The first loan is a conforming Fannie Mae mortgage on the home. The second loan funds the down payment and is secured by the borrower’s pledged crypto, along with a second lien on the home. Better originates both loans, while pledged assets are held in Better Mortgage’s custodial account on the Coinbase platform.

Better’s token-backed mortgage page lists Bitcoin and USDC as accepted collateral at launch. It also says borrowers can use 15-year or 30-year fixed mortgage options, while the crypto remains locked as collateral until the down-payment loan is repaid.

The structure gives crypto holders a way to preserve exposure to their Bitcoin or USDC instead of selling assets to raise cash for a down payment. That can help borrowers avoid an immediate sale and potentially defer taxable gains compared with liquidating crypto before closing.

Joe, the first customer, said he did not want to give up a decade of investing to buy a home. “We closed on our home and my Bitcoin stayed intact,” he said.

No Margin Calls, But Collateral Still Carries Risk

Better’s product removes one of the biggest risks associated with standard crypto loans: market-triggered margin calls. If Bitcoin falls after closing, the borrower is not required to add more collateral only because the market value of the pledged assets moved lower.

The risk trigger is payment behavior. Better says delinquency begins after a missed payment, borrowers have 30 days to bring the account current, and pledged crypto may be liquidated if the borrower remains delinquent for 60 days. Foreclosure proceedings on the home begin separately at 180 days of delinquency under the mortgage framework.

That makes the product different from margin-style crypto credit, where falling token prices can force liquidation even when the borrower keeps making payments. In Better’s structure, the crypto remains pledged for the duration of the down-payment loan and is returned after the loan is fully repaid or refinanced.

The first closing gives Coinbase and Better a working example of crypto collateral inside a Fannie Mae-backed mortgage channel. The product remains limited to qualified borrowers, supports BTC and USDC at launch, and is scheduled for nationwide availability by summer 2026.
