Better Review: 2026 Bitcoin Mortgage Guide

Better and Coinbase announced the first Fannie Mae-conforming crypto-backed mortgage program in March 2026. The structure pairs a standard conforming first mortgage with a separate BTC-pledged second loan that funds the down payment; both loans carry the same rate and term and close simultaneously. Coinbase Prime holds the crypto. As of May 2026, the product is in early access / waitlist phase — not yet available for general origination. NMLS #330511.

The defining feature is the margin call structure — there isn't one tied to Bitcoin's price, ever. Better's exact language: "Bitcoin price volatility has absolutely no impact on your mortgage or your separate down payment loan. There is no top-up requirement. Even if Bitcoin were to drop significantly, you will never be asked to add more collateral." Liquidation is triggered only by 60 days of payment delinquency; foreclosure begins at day 180. BTC advance rate is 40% (pledge $100K BTC, receive $40K down payment credit — 250% collateralization). USDC advance rate is 80%. Coinbase One members receive up to $10,000 in closing cost credits (1% per loan).

Minimum FICO is 680. Full Fannie Mae documentation required: income, DTI, credit, appraisal. Foreign nationals not eligible. Products: 30-year and 15-year fixed. One important detail: the pledged BTC is held as collateral until the entire conforming mortgage is repaid — not just the down payment loan. On a 30-year mortgage, that means Bitcoin is locked for up to 30 years. State availability is listed as "select states" in program terms — nationwide availability is not confirmed. For borrowers who qualify under standard underwriting, no other product in this market removes Bitcoin price volatility from the liquidation equation.

Better is one of several options in the Bitcoin mortgage market. Borrowers often compare it alongside Newrez, Rate, and Milo. Each lender differs on APR range, custody model, rehypothecation posture, max LTV, and state coverage — factors that matter differently depending on your loan size and how much you care about custody transparency. The side-by-side comparison lets you sort and filter all Bitcoin mortgage lenders at once.
