Inventory didn't see the same drop it did the week prior, but it did continue it's downward trend. The week after Thanksgiving provides the only semi-optimal window to list a home for sale in the month of December, as it provides two full weekends of open houses before the holidays roll around and everyone goes off on vacation. I would expect fewer new listings this week and moving forward until January.
4 listings were either cancelled or expired this week, which is a common thing to see around this time of year. We will likely see those homes back on the market in a month or so, because after 30 days you are able to relist your home in the MLS with a fresh days on market counter, giving it the appearance of a "new" listing.
