Scottsdale, Arizona, January 24, 2008 — According to Realty DataTrust, the apartment industry’s first up-to-date source for aggregated leasing data, average nationwide apartment rental rates increased 1.9% in 2007. During the same period vacancy decreased from 5.4% to 5.3%. The findings are based on data collected from nearly 900,000 apartment units nationwide, representing nearly 100 management companies.

A snapshot of current market conditions for all the major metropolitan areas by county is available at www.padzing.com, the reporting site for Realty DataTrust. The snapshot includes pricing, vacancy and rent per square foot by floor plan, making it easy to compare markets.

“Having access to real-time information through PadZing.com is extremely valuable for property owners and managers. Understanding trends that are localized as well as those on a national level helps bring to light rent and vacancy variations and deviations that we used to have to wait months to collect and analyze,” said Jack Kern, an industry consultant and vice chairman of the National Multi Housing Council’s Research Committee.

The reporting site, www.PadZing.com is currently in beta and will be fully launched in the spring with additional tools and an enhanced interface to view data in more detail.
