Short answer: Ask your agent!
Long answer: Often times, the price of using a Realtor during a home purchase can be built into the price of the home, meaning the Buyers Agent is paid by the seller at the closing table. Feel free to ask your Realtor about their fees and how they anticipate them being paid as it can differ based on the agent and the home. Whether these fees are built into the price of the home or come out of pocket, this small investment in your own personal expert and guide is well worth it to save you money and headaches in the long run. The home-buying process is no small feat!
