I am sure you are wrestling with whether or not you want to keep your house on the market during the holidays - many people do. Keep in mind however that you house can't sell if it isn't being made available. You probably won't get many, but the good news is that the showings you get during this time will be from serious buyers - who wants to spend their time kicking tires on houses during the holidays?
Nine properties not only agreed to a contract since Nov 1 but have also closed. (That's roughly the time frame of your question.) Another 8 agreed to a contract and are still wating to clear contingencies in that period. Interestingly those that are waiting to clear contingencies had an average market time of nearly 390 days (it took a long time for most of them to reduce their original price to one that was finally meaningful to a buyer.) Those that have closed had a market time of under 200 days. Apparently they seemed to get the message faster. NB: I do know that several of the closed properties also had major price reductions and a few "re-launched" the listing thus reducing market time. But, they have sold and are on other things.
There is always a buyer for a house. Buyers are just more selective and they know time is on their side. My advice to my listing clients is, Price Is Critical. We need to be ahead of the buyers and competitive properties that are listed as ACTIVE. Using a Sold property as pricing guide is are not as meaningful as it was two years ago. You need to be concerned with current competition.
If your looking to sell, you should definitely keep the house on the market. Undoubtedly, serious buyers feel they can get their best deal during the holidays.
If you're looking to buy, it's a great market and a great time of year to get a good deal.
The serious buyers are very active during this time frame. If one "needs" to buy they are looking everyday. Sellers should keep their homes on the market during this time as well because there are fewer homes on the market, creating less competition. I'm based in Winnetka and would be willing to share actual numbers showing past activity during the holidays.
