Best & easiest way to collect rental data?

[Don Egle]

What is the easiest way to collect data to track rental prices in my area? I'm using a spreadsheet & entering manually. Any sites that will let me download what I need? Any apps that will give me what I need. My area's economy lives off of oil industries and tourism. I see a large increase in distressed housing but very unsure of how far rents may drop. (New Orleans metro area)
