Better, Coinbase Let Lenders Reuse Bitcoin Mortgage Collateral
Better Mortgage and Coinbase have introduced bitcoin-backed home loans that let buyers use BTC to support a conventional mortgage without selling their holdings first. The structure matters because it brings crypto price volatility, custody and counterparty exposure into long-duration housing finance. Unlike a simple collateral account in which assets remain segregated until repayment, the arrangement permits the lender or its partners to reuse — or rehypothecate — pledged bitcoin, potentially giving borrowers a less direct claim on the coins if another party in the chain fails.
Under the disclosed terms, borrowers cannot reclaim their bitcoin until the primary conventional mortgage has been repaid in full or refinanced and the original loan settled. On a 30-year mortgage that is held to maturity, the BTC could therefore remain unavailable for the full loan term while being reused by the lender during that period. The reports did not specify a standard loan amount, launch date or collateral ratio, leaving key details about margin calls, liquidation triggers and protections in an insolvency unresolved.

The history behind this eventCoinbase, Better Expand Token-Backed Mortgages to Coinbase One Members
U.S. homebuyers with wealth tied up in crypto have typically had to sell assets to fund a down payment, potentially triggering taxes and surrendering future upside. Better Mortgage and Coinbase are addressing that constraint by pairing a standard conforming mortgage under Fannie Mae guidelines with a separate loan secured by digital assets. The structure allows eligible borrowers to retain their holdings while using them in the home-buying process, marking another step in crypto’s integration into mainstream U.S. mortgage finance.
Better and Coinbase said on Aug. 26 that the product had become generally available to Coinbase One members on Aug. 12, following its initial announcement in March and a June waitlist. Eligible customers can pledge bitcoin or USDC toward a down payment without selling the assets. Approved borrowers using qualifying Better mortgages, home-equity lines of credit or refinancings receive a lender credit equal to 1% of the mortgage value, capped at $10,000, toward closing costs. Before the full rollout, the waitlist represented more than $260 million in projected loan volume.
Coinbase and Better Unveil Crypto-Backed Mortgage Program
In June 2025, the U.S. Federal Housing Finance Agency directed Fannie Mae and Freddie Mac to explore including crypto assets held by regulated exchanges in mortgage assessments. Coinbase and Better use a two-tier financing structure: a conforming loan that meets Fannie Mae guidelines, paired with a down-payment loan backed by Bitcoin or USDC. This allows homebuyers to avoid selling their crypto and defer capital gains taxes.
On June 4, 2026, Better and Coinbase announced the completion of the first Fannie Mae-backed mortgage secured by Bitcoin. The borrowers were a first-time homebuying couple in their 30s in Ann Arbor, Michigan. The program is expected to roll out nationwide in summer 2026 with 15- and 30-year fixed-rate options. A decline in crypto prices will not trigger a margin call, while Coinbase One members can receive a closing-cost credit equal to 1% of the loan amount, capped at $10,000.
