No set rules for me, but I don't humor buyers when the offer 20% or less then asking price. Guess I don't deal with that sort of thing to well :) Though once I made an offer on something that was for sale after talking to the fellow for a few days, and it was super low- more like a joke- but he accepted it! I was shocked, almost felt bad too. Answering the question at hand low baller comes into play when the deal is only beneficial to the buyer and seems to be screwing the seller- ie not fair market value. ~Tim
