Be careful using one agent to show you a property while thinking you are going to write with someone else. It doesn’t work that way, at least not with the Southland Regional Assoc of Realtors. If an agent shows you the property, they are entitled to the commission. The agents agree to this by participating in the association. The listing agent (or whoever showed the home) would be within their rights to insist that they would be the one entitled to the buyers agent commission. Yes, you can threaten to walk if they don’t agree to allow the discount agent to write and all, but the whole thing just gets real ugly. You’d probably be ahead to ask the listing agent to take 3.5 or 4% to do the whole deal (instead of the 5 or 6% full commission).
