Nothing
All the will be destroyed but you will have to move the family out first.
When your sims move out they go to the family bar in the neighborhood screen
You Beat the wants or in freemode you You evict a family and move in your family
You need to move the existing family out on the neighbourhood menu and then move your new family in.
You could move the house with the family in it to the houses bin then put the house in a new town but if you do this the family cannot move out of that house whilst in the new town. hope that helped
If you click move then they will go onto sims bin on the family icon :)
go to the town menu and they there is a picture of a family with a arrow that stands for move family.if a screen comes up that says "move 'family name'' all personal belonging will be sold for simelons, say yes'.click on the family to move them that moves them to the family "dock." then click on the family an d move them to the house you want
Go to your phone or home computer and choose the "move" option.
You go to your family inventory
Yes
First create your family, then move them into a small house or small lot. Then type control+shift+c and a cheat box should pop up at the top of the screen. Type in "motherlode" for the sims 2 and 3, or "rosebud;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;" for the original sims. Then, move out your family with a button on the top of the neighborhood view for the original sims, and a button in the bottom near create a family for the sims 2. You should then be rich! Pick any big house you want to move your sims into!
If you mean move house you go to the neighberhood screen and when you are on the mini screen at the bottom of the page showing all the familes that could be moved in, on the left there is an icon that has a family icon and a arrow. Click on it then click on the familes house that you want to move out and then they will move out and you can move your Sims Family into a new house :)
