When it sounds too good to be true, it probably is. This particular listing is a fee only listing, "limited service," and the agent simply lists it in the mls. ( You get what you pay for.)
I've mentioned that some agents will likely abuse the short sale listings. This is an example. The Gulf front property is priced at $10,001, but it is a short sale, so lender will have to approve. You tell me if you think a lender will approve of that. It is a gimmick to draw people. If anything, I think it will repel people from "fee-only" agents who aren't willing to accurately market the property. The six photos they have posted in the mls, don't even show an exterior photo of the house.
Listing agent says that the seller wants offers, and he suggests offers start at listing price of $10,001. If you want to have fun, ask him to write up your offers for you at that price. Maybe if he gets enough offers at that price, he will see the the problem with not correctly marketing a multi-million dollar property.
