"My lender says I have to sell my crypto before buying a house." Do you?
Usually not the way they mean it. What your lender actually needs is sourced funds — proof the money is yours and its path is traceable. "Sell it now and let it season for 60–90 days" is the blunt-instrument version of that requirement, used when a borrower can't produce documentation. You have two better options: buy with a fully documented crypto-funded close, or — if you're buying with cash — skip the lender's rules entirely.
