Borrowers can now use $250k in Bitcoin for a house down payment without margin calls, but one trap remains

Lenders now permit borrowers to use up to $250,000 in Bitcoin as a home down payment without subjecting that collateral to margin calls. This lets homeowners access fiat liquidity while keeping Bitcoin exposure, which reduces forced selling and could support price stability. The remaining key risk is counterparty and custody exposure—borrowers must transfer BTC to custodians and still face tax liabilities and potential loss of collateral if they violate loan terms.
