Moving out and back in sounds like way more tedious than simply loading the household to use the money cheat :)
I too wish a more detailed money system in the game. Along with individual accounts, where teen can save up their earnings etc, and it would be good for households that are not really one family (like ya singles, or when a rlative stays temporarily with a family). There should be bank loans with running costs, bank deposits, investments with low or high risk (currently only available to sims in the Business career's higher levels) and more. It should be a rather small job to create such a system as no animations are needed, except a few icons/moods etc which I btw could live without).
Everything in a house would sum up to what we see in the UI today. Gamers not interesting in the details, could just use the main sim's account ignoring all details.
