The fairest way would be to make housing no longer a rare resource. Every week or two weeks, have a script analyze if more than 98% of homes are taken. If yes, then add new ward+subdivision. If during the next week or two week period, more than 98% of homes are taken, add TWO more wards+subdivisions. Next period, THREE. Keep doing this until there are more homes than players+people trying to buy to resell.

I assure you, this will cost less than 1/100th of the cost to do the car pushing simulator part of FF15, and make many times more people happier.
