The CoStar Power Broker Awards recognize the top sale and lease deals completed each quarter. All deals that closed during the previous quarter are evaluated by CoStar’s research team, the largest professional research organization in commercial real estate. The selected top deals and the real estate firms and individual brokers involved in each transaction are singled out for recognition each quarter. For the purpose of recognizing the top property sales each quarter, CoStar uses estimated sale prices in cases where the actual sale price is not disclosed. The estimate uses sale prices of similar properties in CoStar’s property sales database based on the type, age, general size and location as the subject property. All the winners can be found here.
