Real estate data provider CoStar Group has upgraded its COMPS Professional service to include more than 1.2 million sales records. The COMPS tool enables CoStar clients to compare sales of office, hotel, retail, industrial and multifamily properties as well as land sales. As of late November, the total value of all deals covered by the COMPS system was more than $2 trillion.

"This upgrade represents a monumental, multi-year effort to significantly enhance what is already the most comprehensive database of researched and verified sales comparables in the commercial real estate industry," says CoStar president and CEO Andrew Florance.

"Now COMPS subscribers have even more thorough inventory and 100 new features at their fingertips, providing unprecedented insight into commercial market activity and trends. One of the most significant new features is the ability to view for-sale properties alongside sold properties in all three formats — plotted on a map, aerial image or in a table."

CoStar Group (NASDAQ: CSGP) is the largest provider of commercial real estate data and information. The Bethesda, Md.-based company has more than 800 professional researchers who routinely collect and confirm transaction details that include sales price, price per sq. ft., income and expenses, capitalization rate and loan data.
