Money when it comes to investing

[Brad Haughton]

Should I create a second bank account for my rental money to go into or should I just use my current bank account for all the money that's coming in ?

@Brad Haughton  Although not in the same domain, there is a design principle called "Separation of concern" in the world of software engineering. This principle simply supports for separating a computer program into distinct sections such that each section addresses a separate concern.

Keeping your RE investment finances apart from your personal finances may be beneficial. Within your investment account, you may need to further consider 2 separate accounts - one for income and the other for expenses.  

It shows some degree of professionalism IMHO.
