Also to be clear I am talking about condos and therefore sales. Condos can be rented back out, but the majority of large unit buyers are residents not investors. If you look at rental buildings the skew is far worse. There is a 500 unit rental building that opened near me 5 years ago with apparently no units larger than 2 bedroom. Another one with 325 units shows the same. And finally the most recent 605 unit building with, again, no units above 2 bedroom in size. To add insult to injury, many rental building 2 bedroom units are really configured for people to split with a roommate rather than house a family. So to have 3BR+ in the city you need to be wealthy enough to save up down payment money for ownership, and also have income to cover paying both a space and price-per-sq-ft premium.
