Sell. The established path: convert to USD, document the conversion, fund the down payment. It works with lenders that accept documented crypto proceeds, and the sale can be timed to the funding date your lender and escrow approve rather than months early. The cost is the taxable event and — if you cash out through a retail exchange — withdrawal limits and wire timing that need managing.
Pledge. The 2026 development: token-backed mortgage products in the Better + Coinbase mold let qualified borrowers pledge BTC or USDC as down-payment collateral without selling. Read the custody terms before falling in love: these programs require the pledged assets to sit in the partner exchange's custody — coins in your hardware wallet don't qualify until you move them there — and they carry program-specific liquidation and lien terms. They fit borrowers who want leverage, refuse to sell, and are comfortable handing custody to an exchange for the life of the arrangement. They don't fit self-custody holders, and they're irrelevant to cash buyers. The crypto-backed mortgage breakdown runs the full cost-benefit.
Qualify on it. If the problem isn't the down payment but the income line — real holdings, no W-2 — neither selling nor pledging is the answer. A non-QM asset depletion mortgage verifies the holdings, applies a volatility discount, and counts the result as qualifying income over a set term, leaving the coins where they are. Reserves strengthen an application; asset depletion is the application.
Verify. The third path, and the one the industry's exchange-centric framing skips: your holdings can be verified as assets wherever they live — cold storage, hardware wallet, multisig, or an exchange account. A RealScore™ report documents ownership, holdings, and a volatility-adjusted USD value in a form a lender can independently verify — without you moving a single coin. Whether a program counts self-custodied holdings is the lender's call (RealOpen has closed financed purchases where it did). Pair it with a conversion on the approved funding date and you've answered both of the lender's questions with no pledge and no early sale.
