Likely, nothing. In fact, by guiding you to an appropriate offer price and negotiating the deal in your best interest, a good agent can actually put money back in your pocket.
Typically, when a seller lists their home, they agree to pay a commission to the brokerage that is taking the listing. In turn, the listing brokerage agrees to share a portion of that commission with whichever agent brings the future buyer. So, essentially, the seller is the one to pay the buyer's agent. It's important to note, however, that payment is not received by the agent until the transaction has closed. Thus, if you never end up buying a home or don't include your agent's name on the offer to purchase, your agent will receive no payment for their work.
The minimum commission your agent will accept is negotiated between you and your agent as part of the written agency agreement. When you are ready to make an offer on a home, your agent should be aware of the amount of commission being offered to them by the listing brokerage. In some instances, this amount may be more than the minimum your agent required. In other instances, it may be less. If this is the case, your agent may request that you pay the difference between what the listing brokerage has offered to pay and the minimum compensation your agency agreement states your brokerage is to receive.
The knowledge and expertise your buyer's agent brings to the table can save you thousands in your home purchase. Because it is likely that this will be a free service to you, it makes sense to use a buyer's agent. Additionally, if for some reason a portion of the amount you agreed to pay your agent is not covered by the seller or the listing brokerage, we believe the services provided by your agent will be well worth the amount of money you may need to pay for the value given to you.
