Apartments are being massively built now in my neck of suburban Florida. and not condos. They are destined to be ghettos sooner or later. There is obviously some tax loopholes involved. Somebody builds it, sells it along after a few years or less, etc. Rinse and repeat. Take away the financial incentives and you will get more owner occupied condos built.
The story I got from the planning board attorney was that banks were starting to get very restrictive about financing condominium projects, but they had no hesitation about lending money to construct apartment buildings.
