CityRealty, the information resource center for luxury apartments in New York City, announced the launch of its new CityRealty 100. The bimonthly report will be based on the CityRealty 100 Index, which compiles historical sales and current listing data for the top 100 condominium buildings in Manhattan. Highlighting sales and listing activity (along with movement and trends in pricing for top-tier luxury apartments in New York City), the report will be used to track the performance of the CityRealty 100 Index for the preceding two-month period.

"Since 2003, the average price per square foot of properties in the CityRealty 100 has increased at an annual growth rate of 6.2 percent per year," said Pete Culliney, CityRealty's director of research and analytics. "This historical performance compares very favorably to the S&P 500, which has delivered an annual growth rate of 5.1 percent during the same period."
