Here are three shots of move in money my sims got from a legal move. Each sim can move once per age and can only move in by "ask to move in". Merge from family bin isn't allowed except after uni. A good rule early in the challenge when a sim would get 20K from the family bin and less with "ask to move in". Later in the game, a sim could get a much larger amount than 20k resulting in a BIG POINT advantage.

The above moves were a result of moving an elder sims to the retirement house. The move is based on the way I play out my elders. It wasn't to take advantage of something that may not have been considered or thought of when the rule was made.

This realization inspired the vote on a change regarding how sims should be allowed to move around in the neighborhood.
