Is there a good place to find Rent / Property Price disparities?

[Jeff Deville]

I'm new, and it appears that my immediate area doesn't really support cash flow properties, so I'm trying to figure out where else to look. It sure seems like a heat map of Rent / Property Price differentials would be a great first filter. Is there another metric out there that would be better? Does something like this exist?

I was originally going to ask if there was a way to view Cap rates on a map, but it sounds like that might be a more 'game-able' metric.
