There's research that shows why increased housing prices cause increased homelessness. One of the mechanisms is that the family and friends of the homeless can no longer afford the additional space to house the folks who have literally $0 because they themselves are priced out of larger homes or have to rent space to make ends meet.[1]
> Unlike Diona’s mom, Sherman’s parents had extra space. That’s very common among homeowning, empty-nest parents, meaning that a great deal of vacant housing is in the hands of the two people who are most likely to love and forgive an adult child in dire circumstances. But in more expensive regions, fewer parents (or other loving figures) have that resource, either because they couldn’t afford to buy a house in the first place or because there are demands from multiple family members to share the legacy residence.
