Start to Finish Calculations on Evaluating a Property

[Lemanuel Turnipseed]

I’ve been told when evaluating properties to check the numbers to see if the property is a good investment or not. Can someone give me clear and precise step by step instructions on how to evaluate a property. Can you please include the step by step on: single family homes and multi-family homes?  
I am not a BiggerPockets Pro member YET, but started looking at the real property calculator. Or is the Real property calculator all I need to use to evaluate properties?
My goal is to be able to initially see a property, do the numbers (calculations) and then go for it or pass on it...

Thank you.
