If you are the Buyer you typically do not pay the commission. Of course, if you have a Buyerâ€™s Broker agreement with your agent, and you end up contracting to purchase a FSBO that is not offering an agent commission, you could be liable to pay that. You and your agent need to negotiate that, and it should be in line with the norm in your market area. If you are selling, you should at least offer the commission that is typically offered in your area as well, anything lower could prevent agents from actively pursuing to show your home. I know it ethically does not seem fair, but it does happen. Price your home right and list with a great results oriented firm; you will get the most benefit from that by attracting a qualified buyer paying a fair price.
Remember, the best way to increase your bottom line is by having the highest figure possible at the top. Cutting out those middle expenses (commission) will increase your bottom line, but not as effectively as the number at the top - That is the figure to focus on, which is going to bring you the qualified buyer willing to pay what your home is worth.
