I'm familiar with Housing First. I mostly just didn't want to see a misleading use of statistics left unchallenged. Statistics around housing are difficult to grasp, so I often see them used in a misleading way, usually unknowingly.

Take one statistic, the rental vacancy rate in my city, Portland. It has lately been around 4%. Given the number of homeless people in the city, that feels like a travesty. But when you start to do calculations, that turns out to be an average of 2 weeks every four years. If you have tenants moving out after four years, that's barely enough time to do a few repairs, let the paint dry, and finding new tenants. What seemed like a loose market turns out to be a very tight market.
