John, it appears this is actually an advertisement for a mobile home dealer, not an actual property for sale. At least if it is indeed for sale, it's not listed through the local MLS. If you read the description closely though, I think you'll find this is the case. If I'm wrong, sorry!
You can contact the listing agent direct or call any realtor in the surrounding area to find out further details. As a buyer, you have the right to a buyer's agent as well, which I highly recommend. This Realtor you choose to be your buyer's agent can represent your best interests in your real estate goals, at no cost to you since all commissions are paid by the seller. I hope that helps!
