SD – Is it possible to compare that number 1239 with historical trend? Is it possible by those having full access to MLS to make historical queries like “Number of properties for sale on **/01/2007”? Then the query can spew out data for 01/01/2007 .. 09/01/2007. I think Professor Bear’s theory makes a lot of sense. There will be very high pressure to get under the $521K line for anyone in the $522K to, say, $650K range. That should create a compression point at $521K and a vacuum in the $521K+ area, till you reach true estate grade properties at around million $ range. Of course, the crunch is less than a month old. There won’t be enough of data points for at least a couple more months. By 2008, I think this should be obvious.
