Is there a video or recording device in this bookshelf?
It's bad enough that homebuyers are competing with many other buyers. But now they have another disadvantage. More and more sellers have recording & video technology in their homes - spycams. They are able to watch and hear what potential buyers and realtors are saying about their home. Besides being a little creepy, it can drastically tip the negotiations in the seller's favor. This might be the only home you have found that has a certain feature that is critical for your next home. Now the sellers may know that and have heard your excitement about finding the perfect home.
So beware! Whether you are going thru an Open House or touring the home with your realtor, you may be on camera - it gives "Candid Camera" a different twist. The moral of the story is to wait until you are back out to your car before discussing the home with your spouse or realtor.
