“Costar will do everything in their power to make sure you have a memorable experience. I will never forget the friends and connections I was able to make through the lively, fun, and supportive culture at Costar. I thoroughly enjoyed the professional development seminars they provided for the interns as well as the internal professional networking with top ranking members they granted me and my peers with. The rotation of each research department gives you incredible insight to many facets of the CRE market as well as exposure to many post graduate opportunities that they have available. I could not have enjoyed my summer with Costar anymore, it was truly a great experience.”
