You can tell a lot about a real estate market by listening to radio commercials. Like if is in every 3rd commercial suggesting that people should free up cash by refinancing, then it probably means a lot of people are using their home as a piggy bank.
That's why yesterday was a break through for me. I heard my first foreclosure commercial. It wasn't for distressed sellers, it was for buyers looking for cheap homes, but it was still a foreclosure commercial.
This fits with my housing distress signal: Foreclosure Commercials Per Non-Foreclosure Commercials, or FCPNC for short. It's easy to calculate. #Foreclosure Ads / #Other Ads. A value of 0 is the historic norm. Any value greater than 0 means a market is struggling. A value greater than .33 (1 out of 4 ads regard foreclosures) means a market is in a tailspin. A value greater than 1 (over half the ads are foreclosure related) means last person who leaves should turn out the lights.
Yesterday, for the first in my recollection, Seattle's FCPNC was about 0.0001.
