Fannie Mae crypto down payment guidelines: where things stand in 2026

Three separate things are true in 2026, and buyers routinely mix them up: Fannie Mae has accepted documented proceeds from crypto sales since 2022; regulators directed the agencies in 2025 to write rules for counting crypto as reserves without conversion, and those rules still have not landed in the guides; and one branded product lets qualified borrowers pledge Bitcoin as down payment collateral without selling, on terms worth reading twice. Which one applies to you depends on whether you’re willing to convert, and when.

Last checked against the Selling Guide, the FHFA directive, and the product disclosures on September 16, 2026.

The operative rule is Selling Guide B3-4.1-04, Virtual Currency, in force since May 4, 2022. Crypto that has been exchanged into U.S. dollars is acceptable for the down payment, closing costs, and financial reserves, provided the dollars sit at a regulated financial institution and are verified before closing, and provided the borrower documents both ownership of the coins and the conversion. The guide excludes exactly one use: earnest money.

That is the sourcing standard, and it is why the seasoning trap is avoidable. If your conversion is papered and the flow of funds is traceable, you are inside guidelines that have existed for four years. This is the route RealOpen runs: the buyer keeps the crypto in their own wallet until closing, RealOpen converts it to dollars and wires escrow, and the lender receives a record tying those dollars to a wallet the buyer provably owns — documented proceeds on a regular QM or non-QM mortgage, with no 60-day seasoning and nothing pledged. How to build that file: documenting crypto as a source of funds.

On June 25, 2025, the FHFA directed Fannie Mae and Freddie Mac to prepare proposals for counting cryptocurrency held on U.S.-regulated centralized exchanges toward mortgage reserves, without requiring conversion to dollars. Translation: the coins you aren’t spending on the down payment could strengthen your application instead of being invisible to it.

A dated check, because this topic moves: on September 2, 2026 Fannie Mae published Selling Guide update SEL-2026-08 and Freddie Mac published Bulletin 2026-12. Neither touches virtual currency. Fifteen months after the directive, the guides still say convert to dollars, hold at a regulated institution, verify before closing. Where unconverted crypto helps a file today, it is a lender overlay, applied lender by lender, not agency policy.

Note the condition inside the directive itself: held on a regulated exchange. Coins in self-custody do not qualify under that framing, which is a custody tax on the buyers who did the responsible thing. The sidestep is verification that does not require moving the coins: a RealScore™ Report gives a lender proof of self-custodied holdings with a volatility-adjusted value, verifiable by document ID, so the reserves conversation can happen without an exchange in the middle.

On March 26, 2026, Better, with Coinbase as custodian, announced the first Fannie Mae-eligible structure that lets a borrower keep their crypto: a conforming first mortgage paired with a separate second loan collateralized by the borrower’s Bitcoin, which funds the down payment. It reached general availability on August 26, 2026, with the lender reporting roughly $360 million in pre-applications and Coinbase One members offered a 1% lender credit capped at $10,000.

The terms, from the product’s own disclosures: Bitcoin only (USDC was dropped at launch); about $2.50 of BTC pledged for every $1 borrowed; the collateral stays locked until the first mortgage is repaid or refinanced; liquidation after 60 days of delinquency rather than on price alone; and a clause allowing the lender to reuse the pledged coins as long as it keeps an equivalent quantity on hand. The lender’s own framing is worth quoting: nothing in the structure converts crypto into qualifying income or waives debt-to-income limits.

Read it as what it is: a private structure built next to the agency rules, not a change to them. The conforming first lien qualifies the same way any conventional loan does. The “keep your crypto” part is a collateralized second loan with custody terms in the footnotes. We read those footnotes clause by clause in your bitcoin is now their IOU and price the collateral math in the 250% fine print. For most buyers, documented proceeds remain the simpler and cheaper path.

If you’re buying with cash, none of this applies: no agency, no underwriter, and RealOpen converts at closing and wires escrow. If you’re financing, Path 1 is available today with any crypto-experienced lender, Path 2 depends on the lender’s overlay until the guides move, and Path 3 exists if keeping the position is the priority and you accept the custody terms. RealOpen works both lanes: verified holdings up front, a RealScore Report for the reserves conversation, and the down payment converted from self-custody and wired as documented funds — alongside a traditional mortgage from the lender you choose. RealOpen is not a lender and has no part in Path 3.
