I've searched the MLS for this listing and it does not appear. I searched for active listings and sale-pending listings and found nothing. Trulia says they put this listing on their site 4 days ago, but without it being on the MLS I have to wonder where Trulia found it. But I would be happy to do some research for you and see if I can track it down for your.
Without an active listing as a source of information, I don't know if it is a short sale. As for a fireplace, my guess is that, because of the year it was built, it is likely that it does have a fireplace.
I've specialized in Redwood City property for a long time now and can help you if you are interested in having me track down this property. My contact information is below.
