Best (or good) sites for U.S. appreciation info

[Kusum Chanrai]

Hey friends. I have a question about multi-family appreciation:

As I compare deals in different areas, I'm trying to determine the likely appreciation rate, along with how recession-proof each specific building/area is. 

Question: Is there a specific online resource, or set of resources, you guys used to determine how much appreciation one can expect in an area, combined with how likely that building/area is likely to be hit by a property correction in the next few years. 

Thanks! 

Kusum.
