Coinbase and Better Mortgage Launch Bitcoin-Backed Home Loans

Coinbase and Better Mortgage have launched a nationwide mortgage product that allows homebuyers to use Bitcoin as collateral for down payments without liquidating their holdings [2]. The service, which became generally available to Coinbase One members on August 12, targets "crypto-rich, cash-poor" borrowers by enabling them to maintain market exposure while financing a home purchase [2].

How the collateralized loan works

The mortgage structure functions as two distinct loans combined into a single monthly payment [2]. The first is a conventional, Fannie Mae-conforming mortgage, while the second is a loan secured by the borrower’s Bitcoin [2]. To participate, borrowers transfer their Bitcoin into a custodial account managed by Better through Coinbase Prime [2].

The collateral requirements are significant: a borrower must pledge approximately $250,000 in Bitcoin to secure a $100,000 down-payment loan [2]. This effectively limits the down-payment credit to roughly 40% of the pledged asset's value [2]. Better acts as the lender and mortgage servicer, while Coinbase provides the underlying crypto infrastructure and custody technology [2].

Risk and market positioning

The product is designed to help customers avoid capital gains taxes associated with selling digital assets, but it introduces additional financial complexity by layering a second loan onto a home purchase [2]. Unlike traditional margin accounts, Better stated that falling Bitcoin prices do not trigger automatic margin calls or immediate liquidation [2]. Pledged assets only become subject to liquidation if a borrower falls 60 days behind on payments [2].

The companies are targeting a specific demographic: Better reported that 41% of its pre-approved customers meet income and credit requirements but lack the liquid cash for a traditional down payment [2]. Interest from this segment appears substantial, as a waitlist established in June for the product represented more than $260 million in projected mortgage volume [2].

What to watch

• Adoption metrics: Monitor whether the $260 million in projected volume from the waitlist converts into closed loans now that the product is generally available [2].
• Regulatory and tax feedback: Observe how the IRS and other financial regulators treat the intersection of crypto-collateralized loans and real estate, particularly regarding the tax-deferral benefits cited by the companies [2].
• Borrower behavior: Watch for data on how many users maintain their Bitcoin positions during periods of high volatility, given the 250% collateralization requirement [2].

The success of this product hinges on whether borrowers view the avoidance of capital gains taxes as sufficient compensation for the increased leverage and complexity of a dual-loan structure. Whether this model scales beyond the current crypto-native demographic remains an open question for the mortgage industry.
