It’s units, not dollars, so there is no “inflation adjustment” applicable.
Now, what is not reported is median unit price.
Another thing that may be going on is flight to real estate from equity or bond or cash, as an inflation hedge.
Yeah, saw that after posting. I had just read another article on total sales volume and thought this repeated the same. Just goes to show me that I need to read before posting. In that regard, I do wonder if this total sales volume spike is overly influenced by regional factors. For example, is most of the country down but the southeast and south so booming that it skews the total number up?
