Where to find good rental data

[Michael M.]

Hello, 

Does anyone know where I can find an aggregate list of rental rates in a specific market? I'm familiar with websites like Zilpy, Rentometer and Zillow but those services require you to set specific search parameters or even search for specific addresses. It would be much more valuable to me to just look at the raw data, add it to my own map and do my own analysis on it. Does anyone know if this data is available?
