They say there are 3 types of lies: lies, damned lies, and statistics! I love stats as an indicator of trends. Always to be taken with a pinch of healthy suspicion of course. The Redfin Blog is all about analysis of patterns in real estate. And their sample sizes are certainly large enough to give some confidence that the patterns they identify are real. But as always, identification of causal factors, and extrapolation of trends should be a matter for one’s own judgement.
