<b>CoStar's Impact Awards</b> highlight the commercial real estate transactions and projects that have transformed their markets over the past year. The winners are chosen by independent panels of industry professionals who work in the markets they judge. Learn more about the awards <a>here</a>.

CoStar has introduced a new market-based programme recognising 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 organisation in commercial real estate. The selected top deals and the real estate firms and individual agents involved in each transaction will be singled out for recognition each quarter. For the purpose of recognising 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 <a>here</a>.
