The CRS designation is a symbol of excellence in residential real estate. Less than 3% of Realtors have earned this prestigious credential. They have done so through extensive education in a broad range of topics such as negotiations, buyer strategies, investment properties, luxury home marketing, listing strategies, appraisal, law of real estate agency, technology, etc. In addition to advanced training, a CRS applicant must show significant real-world success in closed listings and sales.
