Cap rate pro app

[Luis Saez]

I found what I think is a good app to calculate cap rates. It's called cap rate pro. Have any of you guys used it and if so is it good. Mind you I'm still a noob. I've been going over lots of properties trying to figure the numbers on paper. And this seem to make it easier. I've also stumbled upon a book that I'll be getting by frank gallinelli about cash flow and the formulas used to determine a good investment vs a bad one. Any one read this book before and if so is it worth while?

No clue about that app but a cap rate is a very simple and basic math formula. It is simply the NOI (net operating income) - which is the gross income less all expenses, divided by the purchase price. So if the NOI is $10000 annually, and the purchase price was $100,000, then the cap rate calculation would be 10,000 / 100,000 = .10 which is a 10 cap.
