CS asks: "have condo sales increased relative to house sales since 2008?"
Here are the SFH and condo sales back to 2007.
At first glance it's hard to tell if there has been any shift, so let's plot the ratio of SFH sales to condos.
Now here's something interesting. This year there has been a massive shift towards SFHs. At the same time cheap the skew factor tells us that within SFHs sales are more concentrated on the higher end. The bottom may have dropped out of the market and no one noticed because it was disguised behind higher sales and flat prices.
As boring as this market currently is, there is something brewing and I think many people could be surprised (including myself).
Edit: Some perspective:
I'm quite mystified.. There seems to be some alignment to the market but maybe it's all just random.
