From a marketing perspective, buyers like lots of pictures. It doesn't appear your virtual tour is working, so you'll want to get that fixed and be sure that the virtual tour is included on Realtor.com.
And the old adage of it only takes one buyer is true. First-time homebuyer activity has been brisk and the expectations are that it will continue through November 30th and then expect a drop-off afterwards as many first-time homebuyers are moving up their timeline to buy earlier than they originally planned. It could very well be like the push we saw when 100% financing disappeared. Sales spiked and then dropped dramatically as everyone tried to squeeze in under the deadline.
This will attract fresh attention to the property from homebuyers and realtors checking new listings, and still be within a reasonable timeframe for a buyer to take advantage of the homebuyer's credit.
It also helps to get around the perception that since the listing is now "stale", there must be something wrong or unattractive about the property.
