The house we live in now came with a paper version of this from the original owner/builder (along with almost a "dream" book section of where they got some of the ideas from). It was super helpful to have blueprints and things like paint codes, although the last owner had changed a couple rooms and didn't update it. The last owner did add some details on some plants they put in, which has been really valuable as well. My favorite part has been having receipts for lots of little custom things they added.
