A New Mortgage Product

The mortgage-finance giant Fannie Mae will accept crypto-backed mortgages for the first time, a product developed by Better Home & Finance and Coinbase Global that allows home buyers to pledge their bitcoin or USDC holdings instead of selling them for a cash down payment.

The structure works like this: a borrower takes out a traditional 15- or 30-year Fannie-backed mortgage from Better. Rather than putting cash down, the buyer takes a separate loan collateralized by bitcoin or USDC held through Coinbase. The pledged assets are locked and cannot be traded while the loan is active. If the value of the collateral falls, the mortgage is unaffected as long as the borrower continues making payments, according to Better CEO Vishal Garg.

The Economics

The interest rate on both loans ranges from comparable to typical Fannie Mae mortgage rates to 1.5 percentage points higher. Paying interest on a second loan rather than making a cash down payment increases the total cost of homeownership, but for holders who refuse to sell their bitcoin, the premium may be worth avoiding a capital gains event and maintaining price exposure.

'A lot of those crypto owners and investors have not been able to become homeowners. We haven't really had the best way to service that need.'

Max Branzburg, Coinbase's head of consumer and business products, said the new offering addresses a gap in the market for holders who want to keep their positions while buying a home.

Fannie Mae's involvement is what makes this product significant. The government-sponsored enterprise does not make loans directly; it buys mortgages from lenders, packages them for investors, and guarantees payments. Because Fannie and its sister company Freddie Mac set underwriting standards for the market, their acceptance of Bitcoin and digital asset collateral ripples across the entire mortgage industry.

Regulatory Tailwinds

The product follows Federal Housing Finance Agency (FHFA) Director Bill Pulte's June directive ordering Fannie and Freddie to prepare to count digital assets on mortgage applications, part of the Trump administration's broader support for the industry. About 14% of American adults held Bitcoin or other digital assets in 2025, according to Gallup. A 2025 Redfin survey found nearly 13% of millennial and Gen Z recent home buyers had already sold holdings to fund down payments.

Bitcoin and crypto-backed mortgages are not entirely new. Milo, a Miami-based fintech, has offered them since 2022 and has more than 100 customers. But Fannie's stamp of approval could transform a niche product into a standard offering.

Why It Matters

Forget the 'crypto mortgages' headline. The real story here is Fannie Mae, the backbone of the American mortgage system, recognizing Bitcoin as legitimate collateral. Not through smart contracts, not via some DeFi protocol, not on-chain in any meaningful sense. The custody sits at Coinbase, the loan originates at Better, and the underwriting standards are Fannie's. This is traditional finance absorbing Bitcoin into its plumbing, which is precisely how adoption actually works. Accepting USDC is unremarkable, that is just programmable dollars. Accepting bitcoin is the signal: the most conservative institution in American housing now treats Bitcoin as an asset worth lending against. Every major bank that follows Fannie's underwriting standards just received permission to do the same.
