Yes, someone else made the same valid comment. How many people occupy each housing unit is a huge factor driving "availability". Immigration, I believe, has fallen off. And immigration takes a while to get in a position to buy homes .

My article is only to question what seemed to be accepted truth. For me, the family size is secondary to the expense (workers) need to maintain all housing. As that rises, I believe more people will put their unused property on the market at lower prices. Or, more housing has been built that can be maintained during a recession. We'll see. Thanks for comment!
