There can be affordable market rate housing as well- things like older garden apartments often fill this area in many cities.
We're not talking about the game, so I'm not sure why you brought that up. I was pointing out that higher vanacy rates typically lower rents in my original post. I did not even mention the game.
??? The stuff I've linked to is about building more market rate housing to lower rents and homelessness. I haven't mentioned social housing until you brought it up out of nowhere.
I just pay attention to local politics in the places I have lived in, and notice a lot of NIMBY opposition to new market rate housing.
