"Median" numbers can be tricky. I'm thinking that this might indicate two populations: one that's living in $263,200-and-up houses and condos, and another - probably the majority of people, although in fewer than half of houses - that's living in "old Alaska" frame shacks with unrenovated bathrooms.
The financing aspect hadn't occurred to me, but that's probably a driver for the high prices.
As I said, I wonder what the standard deviations are on those figures.
