I could buy that pond if I could find out who the current owner of it is and was able to reach agreement with that person on a price for the pond. But before doing that I'd want a complete title search done and investigate any clouds on the title, all liens on the property, and in particular what property taxes are owed, so I know what it is going to take to get clear title and what it will cost me. If YOU are interested in buying such a property I'd strongly recommend you consult a real estate attorney to help you sort out all the issues with the property so you know what you are getting into.
