Learn different structures of buildings, construction materials, their features, and their properties. A single Sim will only have $20,000 having left the household. You can use Control + Shift + C to bring up the cheat console and type freerealestate on to give them more options on where to live, but that is up to you. Now you can select where that Sim will live. Pick the Sim, then Move Household onto Lot (the Moving Truck icon) and select OK.
