For years, buying a home meant either selling Bitcoin (and paying capital gains) or leaving it on the sidelines. In 2026, Coinbase and Better launched a third path: pledge your Bitcoin as collateral toward a home purchase without selling it. The first Fannie Mae-eligible crypto-collateralized mortgage closed in June 2026, which makes this a genuinely new option rather than a niche pilot.
This is an independent explainer, not advice. The product is new and some terms come from Better's published materials and reputable coverage; confirm current details with Better before acting.
How it works
The structure is two loans working together, which is the part most people miss:
- A conventional mortgage on the home. A standard, Fannie Mae-eligible conforming loan (15 or 30-year), underwritten the normal way against the property.
- A crypto-secured down-payment loan. A separate, privately financed loan that covers part of your down payment, secured by your pledged Bitcoin or USDC plus a second lien on the home.
You are not spending your Bitcoin and you are not getting a pile of cash. You are using your Bitcoin as collateral so you can put money down on a house while keeping your stack.
What you pledge
Better's published terms ask for meaningful overcollateralization, because Bitcoin is volatile:
- Bitcoin: about 250 percent collateralization, roughly $250,000 of BTC pledged per $100,000 borrowed against it, with about 40 percent of your Bitcoin's value credited toward the down payment.
- USDC: treated more favorably, around 125 percent, since a stablecoin does not swing in value.
So Bitcoin gets you in the door without selling, but you pledge a lot of it relative to what it contributes. Treat the exact ratios as Better's stated terms and verify them directly.
Where your crypto is held
Your pledged crypto sits in Better Mortgage's custodial account on the Coinbase Prime platform, and you retain beneficial ownership of it. This is the key contrast with the Coinbase Bitcoin loan: the mortgage uses institutional Coinbase Prime custody, not the cbBTC-on-Morpho DeFi market. Different product, different rails.
How it differs from a Bitcoin-backed loan
A Bitcoin-backed loan gives you cash (or a stablecoin) against your Bitcoin for any purpose. This mortgage is purpose-built for buying a home: it pairs a conforming mortgage with a crypto-secured down-payment loan. If your goal is liquidity in general, a Bitcoin loan is the tool; if your goal is specifically to buy a house without selling, this is the one designed for it. For the broader category, see our guide to Bitcoin mortgages.
Eligibility and availability
You need a Coinbase account with Bitcoin or USDC you can transfer to Better's custodial account, and a property that is Fannie Mae-eligible. At launch the product supports BTC and USDC (other assets may be added), with a nationwide rollout targeted for 2026. As with any mortgage, you still go through normal underwriting on the conventional loan.
The catches to weigh
- Heavy overcollateralization. Pledging around 250 percent in Bitcoin is a lot of capital committed to a single purchase.
- Liquidation risk on the pledged crypto. A sharp Bitcoin drop can put your collateral at risk on the down-payment loan, on top of normal mortgage obligations.
- Two loans, two sets of terms. The conforming mortgage and the private down-payment loan have different rates and rules; read both.
- Tax. Pledging crypto as collateral is generally not a taxable event, but a forced sale of pledged collateral would be. This area is unsettled, so read our guide on whether borrowing against Bitcoin is taxable and confirm with a CPA. This is not tax advice.
How it compares
This is one of several ways to use Bitcoin toward a home. Others in the market take different approaches, from collateralized non-QM loans to qualify-with-crypto models.
