If your HELOC interest rate is higher than your mortgage rate, there is no way, mathematically for this idea to ever make sense. 

I have developed a mathematical equation how many buyers you need.

If you have $40,000 in cash then I would pay off the AC.However, I personally do not enjoy having debt and there are people who will make the mathematically correct argument that you should not pay it off no matter what as long as you are getting >6% return on that $9,000 somewhere else.

Very mathematical @Jay Hinrichs maybe its market-specific but in my experience, the quickest way to find a good buyers agent for a niche product like an investment or more specifically small multifamily is to start with the large brokers.

That’s $163,333 per acre for those mathematically challenged.

I have mathematically, factually and universally PROVEN already over and over and over again that foreclosure, tax liens divorcee probate etc. etc..

There are so many more options you can do with your money that I probably didn't think of.I teach mathematics at the high school level.

I have a Math degree and my masters is also in core Mathematics, so numbers is my game and I hope this will aid, even slightly when moving forward with this journey.

If you were to look at it from a mathematical standpoint then yes: higher ROI is better for the investor.
