Crypto mortgage: the complete map
Yes — you can use crypto for a mortgage, three ways. Documented proceeds from a crypto sale fund down payments under long-standing Fannie Mae rules; exchange-held crypto increasingly counts toward reserves without conversion; and new collateral-pledge programs let qualified borrowers borrow without selling. What fails underwriting is an undocumented cash-out.
That one paragraph resolves most "crypto mortgage" searches, but the follow-up questions are where deals live or die — and they're the questions loan officers answer worst, because crypto sits at the seam between two industries that don't speak each other's language. Ask a lender and you'll often get the blunt-instrument answer: sell everything now, park the cash for two statement cycles, apply later. Ask crypto media and you'll get the opposite failure: breathless coverage of pledge products with the custody terms in the footnotes.
The truth is less dramatic. Underwriting has one real requirement — sourcing: proof the money is yours and its path is traceable. Crypto satisfies it with documentation that most buyers simply don't know how to produce: wallet ownership verified where the assets live (cold storage included), a papered conversion, and a direct wire to escrow. Buyers who bring that file close on schedule. Buyers who don't get the seasoning speech.
This page is the map of that territory. Below: the deep dive on the seasoning trap, then the specific problems — a flagged deposit, a skeptical loan officer, a reserves question — each answered on its own page. Start with the one that matches the conversation you're actually having.
