Fannie Mae has opened a new path for crypto holders to use digital assets in conforming mortgage underwriting, launching the program through partnerships with Better Home & Finance and Coinbase. The change brings cryptocurrency into the mechanics of U.S. home finance in a more direct way, linking Bitcoin and USDC to a market worth roughly $12 trillion.
The framework allows borrowers to use Bitcoin and USDC in down-payment structures and to count Bitcoin or Ethereum toward reserve requirements. That expands access for households with significant digital-asset wealth, but it does not make crypto-backed mortgages cheap or simple.

The program broadens access, but the math is demanding
The biggest constraint is valuation. Under the guidance, crypto used for reserve purposes is subject to a 50% to 60% haircut, which means a $100,000 Bitcoin position may count as only $40,000 to $50,000 in qualifying reserves. In practical terms, borrowers must hold far more in digital assets than they would in cash to satisfy the same underwriting threshold.
Down-payment financing is even more expensive in collateral terms. Borrowers must post the equivalent of 250% of the down payment in Bitcoin or 125% in USDC to secure a down-payment loan. That structure avoids an immediate sale of crypto, but it also locks up a substantial amount of capital to support a relatively conventional mortgage transaction.
The pricing of the loans adds another layer of cost. Interest rates on these crypto-backed mortgages are expected to come in 0.5% to 1.5% above comparable conventional loans, and the difference can become material over time. On a $300,000 mortgage over 30 years, a 1.5% premium could add more than $111,000 in total repayments across the life of the loan.
Avoiding a forced sale does not eliminate risk
One of the clearest advantages of the program is tax timing. Borrowers no longer need to liquidate crypto immediately to make a standard down payment, which can help avoid a taxable event at the moment of purchase. That benefit, however, is balanced by the reality that the pledged collateral can still be liquidated later if the borrower falls 60 days behind on mortgage payments.
If that happens, the consequences can be severe. A forced sale after delinquency could trigger taxes and expose the borrower to losses if crypto prices have weakened by the time liquidation occurs. What looks like flexibility at origination can therefore turn into a concentrated downside event if both payment stress and market volatility hit at once.
Custody rules also narrow the field of eligible borrowers. Only assets held on U.S.-regulated centralized exchanges such as Coinbase, Kraken or Gemini qualify under the current structure. That excludes self-custodied holdings, staked assets and crypto deployed in DeFi, pushing borrowers toward exchange-held balances and away from more independent forms of digital-asset ownership.
The rollout is the direct implementation of an FHFA directive issued on June 25, 2025, instructing Fannie Mae and Freddie Mac to build rules that let borrowers use crypto as assets without first converting it into dollars. What began as a policy directive has now become a live mortgage product, though one that clearly favors borrowers willing to accept higher costs, strict custody limits and significant over-collateralization.
