Some good souls have uploaded all of the houses into the gallery. That works great expect for the apartments. I did some poking around and if you go into Manage Worlds and click the build button it will bring up the base apartment layout with the furniture. You can copy and paste each room to restore it. For apartments that have two stories, you can do it by story instead of by room. Also, make sure bb.moveobjects is NOT on, otherwise you can stack rooms in the same place over and over, jacking up the price for no reason.
