How to decide if a HELOC for your next deal is a good idea

[Nicholas Dillon]

Hey guys, 

I understand that a lot of time is spent talking about how to leverage your current real estate holdings to obtain new ones.  It is something I am interested in doing in the future, potentially even this year, but I am curious how to put concrete numbers to this decision.  There are a bunch of different figures associated with this decision, such as new interest rate, old interest rate, cash flow of new property etc, but I'm having a hard time getting my mind around how to analyze the decision mathematically.  Any help with this would be greatly appreciated.  Thanks!
