Bad news: I have NO idea.
Good news: your message got posted in an Arkansas forum under "Hunt, AR" vs Hunt TX as your question suggest.
However, this wasn't a total loss! Here is a link for more information on that property:
The company that has the property listed is: Texas Hill Country Properties, their office phone number is (830) 896-7070 & their website: http://www.texashillcountryproperty.com
The description does say: "Waterfront property" but that may not be a river.
I hear the Waco market it BOOMING! Good luck in your search.
