Thanks for the info thus far!
To answer Akil: virtual staging allows images of furniture (couches, tables, beds, window coverings, etc) to be virtually superimposed on a picture of a vacant room. This is typically done by companies with the appropriate software and a library of "furniture" in their virtual warehouse; you submit pictures of your vacant room(s) to them, they add the furniture and submit them back to you. You can then post them on MLS, print them out, etc. It allows potential home buyers to see how the space could be used! From my research, this service is not cheap...but it still could be less expensive than having to buy furniture to stage the property.
Pacita: I like your idea of blowing up the printed images, and displaying them on an easel in the space. This requires a lot less time and energy than hauling bed, couches, tables and so on in an out of a vacant property! Also, if the home seller does not have access to "extra" furniture just lying around to stage a property, there ends up being additional expenses incurred to go out and find all of these pieces.
The reason I posted this question is that I have a home listed that has an unusual layout (an older home that had a couple of additions). Showing agents (and their potential buyers) have commented on the layout, and that their buyers can't really envision how each room could be used (I know...lack of imagination on their part...but some people just can't see the potential in an empty space). My sellers don't want to haul furniture back into the home...so I thought virtual staging may be an option. Just trying to get the opinions of agents who have worked with this technology...either successfully or unsuccessfully!!
Thanks again for all of the input!!
