Hi Steven,
I'm an Agent in NYC and the agents fee is typically 5-6% depending on if they are a former acquaintance or not. There are a couple of things you can do to lower the commission however.
1. In the contract state that if your listing broker brings in the buyer then the commission is lower. Since a standard commission is 6% divided by 2, many brokers will take 4% or 5% if they can also bring in the buyer. This is because they don't have to split it.
2. If you are buying and selling or buying and renting, promise the broker the listing on both sides. If a buyers brokers knows they will get the listing on the sellers end, they are much more likely to work harder, and accept a lower commission when it is time to sell. This is because you promising the agent a double commission. One of my mentors as a standard practice takes 4% on the sellers side if she was the buying broker previously.
Also based on your post it looks like you are buying not selling right now. At least in New York (be i believe in most places), the buyer DOES NOT PAY ANY Commission. If the listing agent you are dealing with is doing this, just make sure your lawyer does not agree to this in any way.
Hope this helps.
Jack
