Coinbase and Better Make Bitcoin-Backed Mortgages Generally Available

The product uses a two‑loan structure with pledged Bitcoin held in Coinbase Prime custody, no routine margin calls, a 250% collateral requirement, liquidation after 60 days of missed payments.

Overview

  • The companies announced general availability Wednesday, offering qualified U.S. buyers a standard Fannie Mae‑conforming first‑lien mortgage plus a separate down‑payment loan secured by the borrower’s Bitcoin.
  • Borrowers must post Bitcoin equal to at least 250% of the down‑payment loan value and transfer the coins from a verified Coinbase account into Better’s custodial account on Coinbase Prime.
  • Daily Bitcoin price moves will not trigger margin calls or change loan terms, but Better may sell the pledged Bitcoin if the borrower is 60 days delinquent on payments.
  • Eligible Coinbase One members who qualify for a Better loan can receive a lender credit equal to 1% of the mortgage value, capped at $10,000 and applied to closing costs.
  • The rollout follows a June test loan to a Michigan couple and a waitlist that showed over $260 million in projected loan interest, and it builds on 2025 FHFA guidance allowing verified exchange‑held crypto to be considered in mortgage underwriting.
