Hm, you know, you’re right, that’s a fairer point than I expected. I think what I hadn’t appreciated (but do now, after thinking through your reply) was how much “back-pressure” the new home construction puts on the market. The current median house price is about double that 200k-equivalent figure, and while the growth in median house size doesn’t directly account for all of that, the availability of new houses is effectively throttled by the size increase so the prices of all houses rise.

I think it was hard for me to imagine, because I have a fairly small house (1800 sq. ft) bought recently, no garage, built in the 50s, oil heating (very old), and it was 600k. Which is massively expensive compared to 200k and has none of the “big excessive new house” traits you’ve mentioned. Median is median, though, I suppose.
