The "Processing Fee" or "Administrative Fee" or "Additional Commission" (whatever they call it) is instituted by the brokers be it a corporate owned brokerage or a small "mom and pop" type company. To the very best of my knowledge, the agents in the Ocean Pines market have nothing to do with it. In most cases, the brokerage will not rescind this charge. That leaves the decision up to the agent. I almost always "eat" the fee since I know my company (and others) won't. I don't know of a single Realtor who likes the fee but many of my peers include it in their marketing, specifically with Buyers since the buyers don't pay commissions (traditionally in this market the Sellers do). This is a growing trend in MD and if you don't see it now you will in the future. Its just a matter of whether the Realtor you work with will consume that fee on your behalf.
I hope that helps.
