Key Insights
- Bitcoin remains invested rather than being sold for the down payment.
- Price declines alone do not force additional collateral.
- Payment failures can ultimately expose the pledged Bitcoin to liquidation.
Better Mortgage and Coinbase have opened a Bitcoin-backed mortgage product to eligible US homebuyers nationwide. The August 26 rollout lets qualified borrowers use Bitcoin collateral for down payments without selling their holdings.
Coinbase One members gained access to the expanded offering on August 12. The companies first introduced the structure in March and completed their first Bitcoin-backed Fannie Mae mortgage in June.
A Two-Loan Structure Changes the Mortgage Model
The product separates the home financing from the cryptocurrency-backed borrowing. Better Mortgage originates and services both loans, while Coinbase provides the infrastructure for holding pledged Bitcoin.
The first loan remains a conventional first-lien mortgage that follows Fannie Mae conforming guidelines. A separate loan funds the buyer’s cash down payment and uses Bitcoin as collateral.
That structure helps the mortgage comply with conventional lending rules. Fannie Mae generally requires cryptocurrency used for down payments to convert into US dollars before closing. The Bitcoin therefore, does not secure the conforming mortgage itself. Instead, it backs the separate down payment loan alongside a second lien on the property.
Borrowers must pledge Bitcoin worth at least 250% of the down payment loan. A $40,000 down payment loan would require $100,000 worth of Bitcoin collateral. Coinbase’s current eligibility information identifies Bitcoin as the accepted collateral at launch. Earlier plans also mentioned USDC, but the present product focuses on BTC.
Bitcoin Volatility Does Not Trigger Margin Calls
The arrangement gives borrowers continued exposure to Bitcoin price gains. However, it also creates risks that traditional mortgage customers normally avoid. Better does not require additional collateral when Bitcoin prices fall. Daily market movements therefore do not trigger margin calls or automatically change loan terms.
Payment delinquency creates a different risk. Better can liquidate pledged Bitcoin after the borrower reaches 60 days of delinquency. Borrowers also cannot trade or withdraw the pledged Bitcoin during the financing period. The collateral is better controlled by Better, thanks to its custodial relationship with Coinbase.
Tax considerations can also be a part of the structure. Cryptocurrency transactions can generate taxable gains if the US tax regulations deem cryptocurrencies to be property. A collateral pledge does not represent an immediate sale, although later liquidation could create tax consequences.
Coinbase One Adds a Financial Incentive
Eligible Coinbase One members can receive a lender credit equal to 1% of an eligible loan amount. Better caps that benefit at $10,000 and applies it against closing costs. The incentive extends beyond the Bitcoin-backed mortgage. Eligible members can also use it with standard mortgages, HELOCs and refinancing products.
Demand indicators helped support the broader launch. A waitlist opened in June generated more than $260 million in projected loan volume. Better said 76% of respondents already held Coinbase One memberships. Meanwhile, 60% said they expected to purchase a home within six months.
Better has originated more than $110 billion in loans. The company also reported that 41% of preapproved customers met income and credit standards but lacked enough cash for a traditional down payment.
Housing Finance Moves Toward Digital Assets
The launch arrives as US housing finance gradually adapts to cryptocurrency ownership.In June 2025, the Federal Housing Finance Agency (FHFA) announced that Fannie Mae and Freddie Mac will be developing proposals to consider cryptocurrency in the mortgage risk assessment process.
They were plans involving verified holdings on the centralized exchanges regulated by the United States. They also needed to take into account the volatility of cryptocurrencies and suitable risk management.
Newrez separately announced in January 2026 that it would begin considering certain cryptocurrency holdings in mortgage applications. For Better Mortgage, the bigger test now involves adoption rather than product availability. High home prices and down payment requirements have created a persistent barrier for buyers with substantial investment assets but limited cash.
The model could expand access for crypto holders, yet it also links housing security to digital asset custody and default risk.
Better Mortgage Chief Technology Officer Ziggy Jonsson said the partnership aims to meet borrowers where their wealth sits. He described the product as another path toward homeownership for people holding more assets on-chain.
Conclusion
Better Mortgage and Coinbase have moved Bitcoin-backed home financing from a limited test into a broader lending product. The two-loan structure preserves a conventional first mortgage while using Bitcoin to finance the down payment.
Its appeal rests on avoiding a forced crypto sale and eliminating price-based margin calls. Yet, due to extended payment delinquency, borrowers continue to run the risk of liquidation.
The next step will tell whether crypto-backed down payments can get beyond the early adopters. If it’s successful, it may have implications for how lenders treat digital assets throughout the nation’s mortgage market.
