Buying my first investment property

[Shay Bond]

Hello, I have been looking around for an investment property for a month. After having a look at several of them, I figured I will create myself a calculator to decide whether the property will actually make any money for me on a monthly basis. Would this be a right way to evaluate whether the property will infact generate some +ve cash flow ? Just wanted to make sure I am headed in the right direction.

Any help will be much appreciated!
