More Homes + House Flipper  

With this mod you will be able to own several houses and even resell them, making the necessary repairs at the request of the client! And also receive a cash bonus from a satisfied customer. Payment depends on your skill level in the repair craft.

Not only that, you can rent out housing, hire servants, gardeners, repairmen and butlers, invite Sims to spend the night, and generally switch between families living in such houses!

Remember to enter the cheat code bb.enablefreebuild before buying a house and before arriving at it.
Tested with LittleMsSam's "More Buyable Seats" and "Life in Business" mods - both mods work great, no bugs or problems were found.
