Better Mortgage and Coinbase announced on Aug. 26 that Better's token-backed conforming mortgage has reached general availability, letting homebuyers pledge Bitcoin as collateral for their down payment without triggering margin calls on day-to-day price swings.
The product uses a two-loan structure. Borrowers take a standard first mortgage from Better designed to conform to Fannie Mae guidelines, plus a separate down-payment loan secured by pledged Bitcoin and a second lien on the property. Under Better's published terms, Bitcoin carries a 40% advance rate, so $250,000 of BTC backs a $100,000 down-payment loan. The Bitcoin is held in Better's custodial account at Coinbase Prime during the pledge period.
Why it matters
This is Bitcoin's first structured entry into the US conforming mortgage market, the country's largest consumer credit channel. The 'no margin call' mechanic is genuinely novel for crypto-collateralized borrowing: most crypto loans liquidate automatically when loan-to-value rises, but Better's structure triggers only on payment delinquency. Borrowers get 30 days to cure a missed payment, and Better says it may liquidate the pledged BTC after 60 days delinquent.
The trade-off is control. Borrowers keep economic exposure to Bitcoin but cannot sell, transfer, or re-pledge it during the pledge period. A forced liquidation after delinquency is a taxable event, the down-payment lender holds a claim behind the primary mortgage holder, and Better's terms say advance rates can change without notice.
Market impact
For Coinbase, the product slots its Prime custody infrastructure into a high-trust consumer use case well beyond trading. For Better, it is a differentiator in a crowded mortgage market. For the wider market, it sets a template other lenders will copy if early performance holds, and it adds pressure on Fannie Mae and Freddie Mac to formalize crypto-collateral treatment in their asset models.
Frequently asked questions
-
How does Better's Bitcoin-backed mortgage actually work?
Better issues two loans: a Fannie Mae-conforming first mortgage on the home, plus a separate down-payment loan secured by pledged Bitcoin and a second lien. Under published terms, Bitcoin carries a 40% advance rate, so $250,000 in BTC backs a $100,000 down-payment loan. The Bitcoin is custodied at Coinbase Prime…
-
What triggers liquidation of the pledged Bitcoin?
Payment default triggers liquidation, not Bitcoin price movements. Delinquency begins the day after a missed payment; borrowers have 30 days to bring the account current. After 60 days delinquent, Better says it may liquidate the pledged Bitcoin under current program terms.
-
Does the borrower keep control of their Bitcoin during the pledge period?
No. Better's terms prohibit borrowers from selling, transferring, re-pledging, or otherwise encumbering the Bitcoin without prior written consent while it sits as collateral. The borrower keeps economic exposure to the price but loses day-to-day liquidity.
-
What are the main risks of using Bitcoin for a down payment?
A forced liquidation after delinquency is a taxable event. The down-payment lender also holds a second lien behind the primary mortgage holder. Better's published advance rates can change without notice. The product also requires a verified Coinbase account, a minimum 680 FICO, and is limited to select states.
-
Who is eligible to apply for Better's Bitcoin-backed mortgage?
Applicants need a verified Coinbase account, must meet Better's underwriting and conforming-loan requirements including a minimum 680 FICO score, and must purchase a home in a state where the product is available. Better's terms do not publish a full state-by-state eligibility list.
