It is the same. You put up your 20% down payment and the bank puts up the other 80%.

If you walk away, you lose your investment, but you aren't on the hook for the money that the bank put up.

It would affect your credit rating (and for musk there would be a similar reputational hit) but neither of you need to pay back the bank.

Well, not always. Banks can add clauses which make you responsible for any losses on the price of the house. In other words, when the price goes below the money owned then that can cause a margin call.

Banks can do that? Or they do do that?

I've never seen this happen.
