I have a family that I created, gave lots of money to via a cheat code, and now I want to move them into a bigger house. The only problem is that I can’t figure out how to get them out of their current house so I can move them into the new house.
In the Neighborhood screen, pick the Family button on the menu. There is a button with the picture of a family on it with an arrow. Click this, then click the house of the family you want to evict.
This will dump that family into the slate of families without houses.
Then you can select them and put them in a new house.
Hope that made sense.
Perfect sense. I got it to work. Thank you so much. I was getting really frustrated here. 
Excellent!
