In an exclusive interview conducted by Ammar from allthings.tv, Ben Van Dyk of Farm.tv stated that he sold Property.tv for $100,000 in 2007. Ben mentions he has all the documentation on the sale, it was not reported to DN Journal.
I will not post the interview here as the interview is an Allthings.tv exclusive. Here is the link for those that want to read it. It is a very good interview from one of the top .tv domainers.
Update: Allthings.tv is no longer a working website.
