Fannie Mae to Accept Crypto-Backed Mortgages. Here’s What That Means for Buyers

Fannie Mae just stepped into the crypto conversation in a way that could actually change how some buyers get into homes.

According to a new report from the Wall Street Journal, a partnership between Better and Coinbase will allow buyers to use crypto as collateral for a down payment instead of selling it. 

That means someone holding bitcoin or USDC could move forward with a purchase without liquidating their position.

This isn’t some fringe experiment anymore. About 14% of U.S. adults already own crypto, and nearly 13% of younger buyers have sold it to fund a home purchase. 

There’s a clear gap between people who have assets and people who have usable cash, and this product is trying to bridge it.

Before this starts showing up in your conversations with clients, it’s worth understanding how it actually works and where the risks start to stack up.

How the Crypto Mortgage Structure Actually Works

You’re still looking at a traditional mortgage on the surface, but there are two moving pieces behind it:

• A standard 15- or 30-year mortgage through a lender like Better, which then gets sold to Fannie Mae
• A second loan backed by crypto, used to fund the down payment

Instead of bringing cash to the table, the buyer takes out a second loan backed by their crypto holdings. Assets like bitcoin or USDC are pledged as collateral, and that loan is used to cover the down payment on the primary mortgage.

Once those assets are pledged, they’re locked. The borrower has to hold them in a Coinbase account, and they can’t be sold or traded during the life of the loan. 

The crypto sits in custody, and if everything is paid off as agreed, it’s returned to the borrower at the end.

Both loans are issued and held by the same lender, so the borrower makes a single monthly payment that covers everything. And even if the value of the crypto drops, the loan terms don’t change, as long as the borrower keeps making payments.

A simple example helps make this real. On a $500,000 home, a buyer could pledge $250,000 in bitcoin and use that to secure a $100,000 loan for the down payment. 

From the outside, it looks like a normal purchase. Behind the scenes, it’s a more layered structure that adds cost and complexity in exchange for keeping those assets invested.

What This Means for Buyers, Costs, and the Market

This product is built for a very specific type of buyer. 

They have the assets. They just don’t want to turn those assets into cash.

That hesitation has kept a lot of people on the sidelines. This gives them a way in, but it comes with tradeoffs that need to be explained clearly.

Here’s where this starts to show up in your conversations:

• Buyers who have enough crypto to cover a down payment but don’t want to trigger capital gains taxes
• Clients who are bullish on crypto and don’t want to miss future appreciation
• Younger buyers who haven’t built up traditional savings but have invested in digital assets
• High-asset borrowers who don’t fit cleanly into standard underwriting boxes

This is where the deal gets more complex financially.

Instead of one loan, they’re now paying interest on two. That alone increases the total cost of the purchase. Rates can land close to standard mortgages or come in up to 1.5% higher, depending on how the deal is set up.

There are a few offsets worth noting:

• No private mortgage insurance on the second loan
• Potential yield from assets like USDC that could help offset some interest
• A 1% rebate for Coinbase One members, capped at $10,000

Even with those, this strategy is about liquidity, not improving affordability.

The other piece you can’t ignore is how volatile crypto prices can be. Bitcoin is already down more than 40% from its October peak. The loan terms don’t change if values drop, but the borrower is still locked into that position, which can create a different kind of pressure.

Right now, this is still a small corner of the market. Some lenders have experimented with it, but adoption has been limited. 

What changes here is Fannie Mae stepping in. Once that happens, products like this tend to get a lot more attention, and a lot more usage.

When it comes to your role as the agent, this is less about becoming a crypto expert and more about being able to walk a client through what they’re actually signing up for.

What This Means Going Forward

Fannie Mae stepping into this space is what makes this worth paying attention to. 

This isn’t the first time anyone has tried a crypto-backed mortgage. Companies like Milo have been offering similar products since 2022. The difference is those loans have stayed on the fringe, often more expensive and less flexible, with limited reach.

Once Fannie sets the standard, more lenders tend to follow. And what starts as a workaround can turn into a real option buyers start asking about.

There’s also a bigger idea sitting behind this. Right now, the focus is on bitcoin and USDC. The infrastructure being built here is designed to go further, potentially allowing buyers to pledge other assets like stocks, mutual funds, or even holdings in an IRA.

You don’t need to become a crypto expert to handle this. You do need to understand how the structure works and where it can go sideways.
