Finding market cycle information? Philadelphia

[James Hendricks]

Hey everyone,

Im wondering about the best sources for rent and occupancy rates? I know about the services Costar offers, but I'm wondering who or where typically has this information on hand locally? And also how far broken down is this information is in regards to submarkets in and/or around the metropolitan area and city proper? 

I have done a brief search online to no avail. I could have been looking in the wrong place, but I like the idea of going and talking to someone in person anyway. Any information will help and I appreciate it.

Thanks,

James
