Crypto and Mortgage Qualification: What Fannie Mae's Rules Actually Say

Corrections, September 8, 2026. An earlier version of this article, headlined “Fannie Mae Now Accepts Crypto-Backed Mortgages,” had the policy backwards. Two corrections:

• It said Fannie Mae was accepting cryptocurrency-backed mortgages for the first time. Fannie Mae has not changed its policy. The product described is a private lender offering from Better Home & Finance with Coinbase. Fannie Mae buying a conforming first lien does not make it a Fannie Mae crypto program.
• It said a 2025 FHFA directive reversed Selling Guide B3-4.1-04, “which had blocked digital assets from underwriting since 2022.” B3-4.1-04 never blocked digital assets, and it has not been reversed. It has permitted virtual currency, once exchanged into U.S. dollars, since May 4, 2022.

Several unsourced figures from the earlier version have been removed rather than restated: a June 2025 FHFA directive on crypto as reserves, a 50 to 60 percent volatility haircut, a named Senate bill, and a rate premium range. None could be located at a primary source.

What Fannie Mae’s rule actually says

Selling Guide B3-4.1-04, Virtual Currency, took effect May 4, 2022 under Announcement SEL-2022-04. It permits virtual currency, and it always has (Fannie Mae Selling Guide B3-4.1-04).

The conditions have not changed:

• Virtual currency must be exchanged into U.S. dollars before the funds count.
• The funds may be used for down payment, closing costs and reserves.
• The borrower must document the exchange, and the resulting funds must be held at a U.S. or state regulated financial institution.
• Virtual currency may not be used for earnest money.

So the rule is not a barrier that was recently lifted. It is a conversion and documentation requirement that has been in place for more than four years, and it is still in place today.

What the Better and Coinbase product is

On March 26, 2026, Better Home & Finance and Coinbase announced a product that lets a borrower pledge Bitcoin or the USDC stablecoin as collateral for a mortgage down payment. The description below is drawn from the companies’ own announcement, which is a private company release rather than a regulatory source.

According to that announcement, the borrower takes a standard 15 or 30 year conforming first lien through Better. Instead of bringing cash to closing, they pledge crypto held at Coinbase, which transfers to a Better custody wallet and secures a separate, privately financed second loan that funds the down payment. The borrower keeps ownership of the pledged asset and does not sell it, so no capital gains event is triggered. The companies state that a fall in the asset’s value does not change the mortgage terms and that there are no margin calls, with liquidation risk arising only after a 60 day payment delinquency.

Read carefully, the structure is the point: the crypto never enters the conforming loan. It secures a private second lien that sits outside Fannie Mae’s guidelines entirely. The first lien is an ordinary conforming mortgage, underwritten to ordinary rules, and that is why Fannie Mae can buy it. Nothing in this arrangement required Fannie Mae to change anything, and nothing in it means Fannie Mae accepts crypto.

What this means for lenders

The immediate practical impact is narrow. This is one product, from one lender, with one exchange. Most lenders will not be originating anything like it soon.

The borrower conversation is the part that arrives sooner. Redfin reported in 2025 that more than 10 percent of millennial and Gen Z homebuyers sold crypto holdings to help fund a down payment. Those borrowers are in the pipeline now, and some of them will ask whether they have to sell.

The accurate answer, and the useful one, is the rule above: they do not need a special program, they need to convert and document. Under B3-4.1-04 a borrower can liquidate virtual currency into U.S. dollars, evidence the exchange, season the funds at a regulated institution and use them for down payment, closing costs or reserves on an ordinary conforming loan. That path has existed since 2022 and needs no second lien, no custody arrangement and no counterparty.

Credit scoring is untouched by any of this. Crypto collateral speaks to funds, not to the borrower’s credit profile. A borrower who is asset rich with a 680 FICO® score still prices off that score. Rescoring is where that moves: Score Express℠ delivers an average of 23.9 FICO® points per change, each individual tradeline update, with standard 72 hour turnaround. Results depend on what is correctable on the specific file.

What to watch

The honest list is short, because most of what circulates on this topic is not sourced:

• Whether FHFA issues any published direction on virtual currency in single family risk assessment. As of this review, no such direction appears in FHFA’s news releases, statements or advisory bulletins.
• Whether Fannie Mae amends B3-4.1-04. Any change would appear in the Selling Guide and in a Selling Guide Announcement, which is where to check rather than a press summary.
• Whether other lenders build comparable private structures. That is a lender product question, not a GSE policy question, and it should not be reported as the latter.

For lenders, the underlying credit reporting mechanics do not change. The tri-merge report, the merge logic and the bureau level data remain the foundation of qualification. What varies is the asset side, and on the asset side the governing document is the Selling Guide.
