Crypto as a Down Payment for a German Mortgage: What Banks Require

No, you cannot buy a house in Germany with Bitcoin. Since April 1, 2023, section 16a of the German Money Laundering Act has banned exactly that: the purchase price for a domestic property may not be settled in cash, nor in crypto-assets, gold, platinum or gemstones, whatever the amount involved. Your Bitcoin holdings still work as a down payment for a mortgage, but only along a single route: you sell them, have the euro amount paid into an account in your own name, and prove to the bank and the notary, without gaps, where the money came from.

That shifts the real task away from the purchase and towards the paperwork. Anyone who has moved coins across several wallets and exchanges over the years rarely fails on the value of the portfolio, and almost always on the missing proof of origin. This article sets out what German banks accept as a down payment, which documents close the chain, how the holding period changes the sum available to you, and in which order to proceed.

Can you pay for a property in Germany directly with Bitcoin?

The short answer is no. The reason lies in an explicit statutory rule, not in the convenience of the banks. The Money Laundering Act, GwG for short, is the German law that requires banks, notaries and other obliged parties to check and document the origin of the assets used. Since 2023 it has contained a prohibition of its own for property transactions.
