Coinbase and Better Expand Bitcoin-Backed Mortgage Access
Coinbase and Better Mortgage have expanded their Bitcoin-backed mortgage product, giving eligible homebuyers a way to use BTC as collateral for a cash down payment without directly selling their Bitcoin.
The structure combines a standard conforming mortgage backed by Fannie Mae with a separate loan secured by pledged Bitcoin. Better originates and services both loans, while the pledged BTC is held in custody through Coinbase's platform.
The approach creates a new bridge between cryptocurrency wealth and traditional home financing, allowing Bitcoin holders to potentially access homeownership while maintaining exposure to BTC.
How the Bitcoin-Backed Mortgage Works
The product uses two separate loans.
The first is a conventional conforming mortgage secured by the property. The second provides the cash needed for the down payment and is secured by the borrower's pledged Bitcoin and a second lien on the property.
Better says borrowers can receive 40% of their pledged Bitcoin's value as down-payment credit, requiring Bitcoin collateral equal to 250% of the down-payment loan.
For example, $100,000 worth of Bitcoin can support a $40,000 down-payment credit under the current structure.
This means a borrower does not have to sell the BTC to generate the cash required for the down payment.
Bitcoin Stays as Collateral Instead of Being Sold
One of the main attractions of the structure is that borrowers can maintain their Bitcoin exposure.
Instead of selling BTC and converting the proceeds into dollars, the borrower pledges the Bitcoin as collateral. Better then holds the pledged assets in a custodial account on the Coinbase platform until the relevant loan is repaid.
The structure can therefore appeal to Bitcoin holders who have substantial digital-asset wealth but do not want to liquidate their holdings to purchase a home.
Coinbase says the product is designed to provide a pathway from digital-asset ownership to homeownership while retaining the structure of a conforming mortgage.
No Bitcoin Margin Calls From Market Movements
A major difference from traditional crypto-backed lending is how the product handles Bitcoin price volatility.
Better says changes in Bitcoin's market price alone do not trigger margin calls or additional collateral requirements.
That means borrowers are not required to continuously add BTC if the cryptocurrency falls in value.
However, the pledged Bitcoin is not completely protected from liquidation risk.
Better says it may liquidate the collateral if the borrower remains delinquent for 60 days. The risk is therefore connected to repayment performance rather than ordinary day-to-day Bitcoin price movements.
Coinbase One Members Can Receive Up to $10,000
Coinbase One members receive an additional incentive through the partnership.
Eligible members can receive 1% of the applicable loan amount in lender credits, up to $10,000, toward closing costs and fees. Better funds the credit.
The benefit is not limited to the crypto-backed mortgage structure. Coinbase's official information says the rebate can also apply to eligible traditional mortgage, refinance and HELOC products obtained through Better.
This could make the offering more attractive to Coinbase customers who are already considering purchasing property.
Why Fannie Mae Matters
The most important part of the structure is that the primary mortgage remains a conforming Fannie Mae-backed loan.
Bitcoin is not being placed directly into the conventional mortgage. Instead, the separate down-payment loan is secured by the pledged cryptocurrency.
This distinction allows Better to maintain the first mortgage within the framework used for conventional conforming loans.
Fannie Mae's existing guidance generally requires cryptocurrency used directly for down payments, closing costs or reserves to first be converted into U.S. dollars and verified before closing.
The Better-Coinbase structure works around that issue by separating the crypto-backed financing from the conforming mortgage itself.
Bitcoin Collateral Could Change Crypto Wealth Management
The product represents a broader shift in how cryptocurrency wealth can be used.
Bitcoin holders traditionally have had several choices when they needed liquidity: sell BTC, borrow against it through a crypto lender, or potentially use other financial assets.
A mortgage structure creates another option.
Instead of immediately converting Bitcoin into dollars, an eligible borrower can potentially borrow against the asset to fund a home purchase while continuing to hold the underlying BTC.
That could become particularly relevant for long-term Bitcoin holders whose net worth is heavily concentrated in cryptocurrency.
Coinbase and Better Are Building a Larger Crypto Finance Platform
The mortgage partnership is part of a broader expansion of crypto into conventional financial services.
Coinbase has increasingly moved beyond cryptocurrency trading into areas such as lending, payments and other financial products.
Better, meanwhile, is using its mortgage infrastructure to connect traditional home financing with digital assets.
The companies originally announced their partnership in March 2026, describing it as a new pathway for Americans holding Bitcoin or USDC to fund a home down payment without liquidating their digital assets.
Better's current product information states that Bitcoin is the accepted collateral asset at launch, while other assets such as ETH and SOL could potentially be added in the future.
The Risks Behind Bitcoin-Backed Home Financing
Using Bitcoin as mortgage collateral does not eliminate financial risk.
Borrowers remain responsible for their mortgage payments, while the pledged BTC remains locked as collateral for the relevant loan.
A prolonged payment delinquency can ultimately result in liquidation of the pledged cryptocurrency.
There is also an opportunity cost. A borrower keeps exposure to Bitcoin's potential upside, but that also means maintaining exposure to one of the most volatile major financial assets.
Mortgage rates, loan terms, collateral requirements, taxes and eligibility requirements should therefore be evaluated before using the structure.
Bitcoin Moves Deeper Into Traditional Finance
The Coinbase-Better mortgage demonstrates how Bitcoin is increasingly being integrated into traditional financial infrastructure.
Rather than forcing cryptocurrency holders to exit their positions before accessing conventional financial products, lenders are experimenting with ways to use digital assets as collateral while keeping the underlying financial product familiar.
For the borrower, the result is a traditional home mortgage combined with a crypto-backed financing layer.
For the broader financial industry, it represents another step toward connecting Bitcoin wealth with established markets such as real estate.
What Bitcoin Investors Should Watch Next
The success of Bitcoin-backed mortgages could influence how other financial institutions approach cryptocurrency collateral.
Future developments could include additional eligible digital assets, new forms of crypto-backed lending and broader integration between cryptocurrency custody and traditional financial services.
For now, the Coinbase-Better model offers Bitcoin holders a new way to access home financing without immediately selling their BTC.
The key idea is simple: instead of converting Bitcoin into cash to buy a home, eligible borrowers can pledge BTC as collateral while keeping the primary mortgage within the conventional Fannie Mae framework.
