Most of the affordable rentals in my city and many others is luxury housing that was built ~100 years ago. They built lots of cheap housing back then too, but it was junk that was torn down a long time ago. The luxury stuff was built better and lasted. The affordable housing from ~50 years ago was single family housing and is crazy expensive today. We should be building lots of high density luxury condos today. Those are the affordable apartments of the future.
