Better Can Reuse the Bitcoin Pledged Against Its Coinbase Mortgages

Borrowers who pledge bitcoin against a Better mortgage may not get the same coins back. The company said in a written response to CoinDesk that it may rehypothecate the pledged bitcoin, provided it keeps an equivalent amount on hand to return at loan payoff. Rehypothecation is the term for a lender reusing collateral a borrower has posted. It is ordinary in prime brokerage and less expected in a product sold on the idea that the borrower keeps their bitcoin. Better puts pre-applications since the public launch at $360 million.

What the borrower is actually holding

The pledge is not a box with a name on it. On CoinDesk's account, published on Sunday afternoon, a borrower who repays receives an equivalent quantity of bitcoin and not the specific coins deposited, which turns the claim into a promise against Better's inventory instead of a segregated deposit. The collateral sits in a Coinbase Prime account that Better controls, a structure both firms described at launch. CoinCentral and parameter.io carried the same disclosure on Monday. All three trace to one written response, so it is a single company statement in three renderings rather than three confirmations. Better set out the product's limit in the same reply.

"Nothing in the product converts crypto holdings into qualifying income or waives DTI or credit thresholds. The Bitcoin loan only solves the cash-for-down-payment problem," the company said.

DTI is the debt-to-income ratio a lender tests before approving a mortgage.

The mechanics have not changed

Two loans still close at once, a Fannie Mae conforming mortgage on the house and a bitcoin-secured loan covering the down payment, at the same rate and the same amortization, fixed for 15 or 30 years. The collateral requirement is 250%, so $250,000 of bitcoin supports $100,000 of borrowed down payment. A falling bitcoin price triggers no margin call. Liquidation is permitted only after 60 days of missed payments and after notice, and Better said it would sell no more than needed to clear the arrears, with foreclosure available at 180 days under Fannie Mae's guidelines. The bitcoin does not come back until the conforming mortgage is repaid or refinanced, and the down-payment loan cannot be settled on its own. This desk covered the loan when it reached all 50 states in August.

Two demand figures, and neither is a loan

How large the pipeline is depends on which count is used. Better's waitlist carried about $260 million in projected volume before general availability, on figures The Block published on 26 August, when 76% of respondents were already Coinbase One subscribers and 60% expected to buy within six months. The $360 million reported on Sunday covers pre-applications taken after the launch, and 35.9% of those applicants hold more than $500,000 in crypto, with 38% intending to buy inside three months. Those are different populations at different moments, not a revision of one number. Both remain expressions of interest. Better has funded roughly $110 billion of loans over its history, and says 41% of its pre-approved customers clear the income and credit tests but lack the cash for a down payment.

Nobody agrees when it launched

Two plain facts about the product are still reported inconsistently. The Block, citing HousingWire, dates general availability to 12 August. CoinDesk calls it late August. CoinCentral and parameter.io both give 27 August as the public launch. No account acknowledges another's date. What may be pledged splits the same way: CoinDesk says bitcoin only, with USDC dropped from the original plan, while The Block's August report has both bitcoin and USDC supported, and Coinbase's March announcement settles neither. Better's crypto mortgage page returned an error when checked on Monday, so no primary listing could be consulted. Reusing posted collateral is where much of the industry has been heading anyway, and Kraken began accepting tokenized stocks as margin earlier this year. Whether any of the $360 million has become a closed loan is the figure nobody has published.
