I don't know where else to post this.
If SE were to create more subdivisions in the housing area to substantially increase the number of houses it would serve four main purposes.
1. Satisfy the number of players wanting to buy a house.
2. Ensures the vast majority of FCs get a house. This is an issue for those that want to change the color of the chocobo, training the chocobo, or when trying to grow things (minions to name one).
3. Credit Dump - albeit a weak one that can be overcome easily.
4. Won't penalize people for having school, work, family, business, a life outside of those areas, or needing to eat, drink, sleep, use the water closet.
After some deliberation, how it would work, overall but not all encompassing, is when all the housing areas main and subdivisions reach 90% capacity a new subdivision in then created. Then a third subdivision is created when all the housing areas, subdivision one, and subdivision two are 90% full another is created.
They can ensure the plots do not devalue and/or increased the price by 125-200%.
