Calculating numbers to ensure deal is worth it

[Matthew Swearingen]

Is there a calculator or an app that when I locate a investment home to buy I can plug in ALL the pertinent numbers to tell me exactly what my COC and passive income will be?

Also, is there way once I locate an area to invest in a simplified way to locate homes and look at purchase price and be able to determine what it would rent for. What I have been doing is getting on Zillow and looking for home for sale in a particular zip and then looking for rentals in that zip. I would think there's an easier way to do this...maybe?

I have been looking at Indianapolis and Columbus. Any input would be appreciated.
