I have a simple question about family and personal inventory, and moving

I've had a sim's house transfer with her from Bridgeport to Winfield after saving it to the library and porting her into the Winfield legacy.It's the only way to have the house go with the sim.I usually prefer to start with just one couple in an empty world and play though them getting settled in and getting a house built on their empty lot before other families begin arriving and settling in to build homes on their lots.
