A few questions first:
What have you "not been able to get it off the ground"?
What do you mean "not been able to get it off the ground"?
Are you no longer an agent in Cape Cod?
I'm not sure how much and agent would be willing to spend, as they could just buy
www.capecod-condos.com, and the search phrase "cape cod condos" doesn't get all that much traffic anyway. But being that you've had it a few years, and it is indexed by the search engines, that makes it a little more desirable...
You may want to spend a little time and effort for a few months and get it scoring well in the search engines, then it would be worth MUCH more. (of course then you may not want to sell...)
