So the scam here doesn't seem to be ACTUALLY selling the land--it's basically engaging a realtor long enough to get earnest money on the table, then to disappear. Although if they could go far enough to get an entire amount wired to them I'm sure they'd take it.

Since a lot of people are doing all cash (non-financed) deals lately, I could see how a scammer and a lax realtor could possibly scam an overzealous buyer out of the full amount.
