After the National Association of Realtors settlement took effect in August 2024, buyers working with a Realtor sign a written agreement before touring homes. Read the pay terms and the length of the agreement.
Ask how many homes the agent sold in your city or school district in the last year, and at what price compared with the list price.
Many agents work in teams. Ask who answers your calls and who attends showings and inspections.
