How to Fix Housing Without Everyone Freaking Out

My biggest concern though is that the already shaky game economy would see a meteoric rise in prices if a few hundred million came rolling back all at once.

This is true but don't forget that much of this money will be sitting on inactive accounts that very well may never return to the game. On top of that, the person purchasing the house next time would be removing that money from the economy and the next person will only receive 80% of that.
