I "think"(?) Black and White had sold out of nearly all non-penthouse inventory when 989 hit the market (or at least they were in the final stages of their sales campaign). YoY is definitely filling that niche, too!
Most projects will include end-user focused inventory but you'll see that as premium one+den 1BR's and 2BR's+ which investors are far less likely to take up. The investor market is looking for studios, junior one's and 1BR's in order to make the whole gig work out financially.
