And I think this is really crummy and unfortunate. Myself, my wife, and my one child would be very happy in a 1,300 sqft house but really don't need or want a 2,600 sqft house. So house prices increasing along with house size is still problematic.
But that 1300sqft was average. Which meant a lot of homes were smaller than that. My brother once owned a 600 sqft detached house from that era.
