AFAIK in the US you can buy/sell a house with an anonymous LLC. It's not clear to me you would even need an ID in the process, although that may vary by state. Definitely wouldn't need the rest of the stuff, except the money.
Buying a house doesn't require much ID. Borrowing money for it probably requires KYC, but maybe not exactly ID. Selling a house usually wants a notarized signature and notaries check ID (or are supposed to).
