I don't exactly get how the 6-plexes will work. If 3 are "affordable" and 3 are market rate, aren't the market rate prices going to just subsidize the below market units such that they will actually be above market? Half and half seems like too high a ratio for cost offsets to not be onerous. Isn't the best way to make things more affordable just to build more in general? I'm admittedly no policy wonk in this area, but I just don't see how that math can work.
I have no idea about the details on the affordable units. Adding a few affordable units to a large apartment development gets you some preferential treatment through the permitting process to an extent that most big developments add 10% low income. There is a pretty big pot of money that they could be using to encourage low income housing but once again I'm not up to date on how that is being implemented. A fair amount of time efforts geared toward encouraging low income housing don't work all that well and that could be the way it goes here.
