Comps - Comparable Listings - apps / sites to generate them?

[Patrick DiDomenico]

Is anyone familiar with apps or websites that automatically generate comps (comparable listings) for houses? My problem is time. It can take an agent a few days to come up with comps and the "report" is not the most user friendly (old school PDF that is clunky and not built for easy, fast analysis. I need a quick read so that I can make a fast, informed decision. 

With all the MLS (and other) data on home sales, it should be pretty straight-forward to make an app or website that allows you to input a few data points about your target house and get comps instantly.

Any recommendations or ideas are greatly appreciated. 

PS - I am a buy and hold investor in the Syracuse, NY area. Happy to connect with others. 

Thanks!
