Publish the actual paper or this is just vaporware nonsense. This is a non-peer-reviewed paper with zero credibility, thats been seen by a small handful of people. They could literally write a paper about the moon being made of cheese and have the same credibility. They dont even make the source material available in their article.
I dont want to sound overly critical, this looks like a legit finding that matches up with my experience of the housing market, but Im completely fed up with people publishing their "findings" without reporting where the data came from and how they got to their conclusions. Until they publish the paper, this should be dismissed out of hand. There's such a long history of people completely messing up their statistical methodology that you cant believe anything until you see the actual numbers/methods.
