Dont read too much into what happens the first few days of the year. Lots of agents enter expiration dates for listings of 12/31 or 1/1 so a ton of listings fall off the market at teh end of each year. This year about 1000 fell off when we were declining by 500 each of the weeks before. Now that everyone is geting back to work, you will see alot of agents put the listings back on that fell off when they were busy over the holidays.
Right now we are under 15,000 listings. If we hit 20,000 by the end of January I would say that was a very ominous sign. Check the short sale monitor each week as I will provide updates.
