Looking for a house we could house hack, had an incredibly low interest rate on mortgage and house has increased in value about 42%, an estimated 180k in equity.

The Heloc can also pose as a debt obstacle since its an open end mortgage a.k.a credit card.a mortgage is also set up over 30 years so it offers a lower rate and payment. 

Yes, the lender was Premium Mortgage.

Does the operational company already exist and have income history?

And how do I roll this into a cheaper mortgage (my dti would be too bad for another conventional).Maybe a lender would be able to consider the electric "working" with the proper inspection?

Quote from @Ven Bud: After hearing to lot of bp episodes on negative cash flow, I have a question.I am currently living in my primary residence and planning to purchase an investment property, and obviously it is going to be a negative cashflow (bay area), but I am of the opinion that as long as the rent on the investment property is atleast going to be greater than my current primary residence mortgage it can still considered as positive cash flow investment.The investment property is going to be in a much better location (for office commute, bay area proximity) than my primary residence.

There's obviously opportunity here to build this out and turn it into a basement apartment, which I think would cash flow because of course there's no mortgage. 

Consult your tax professional: while podcasts are great, make sure you have an existing relationship with a tax professional you can trust.

I would like a payoff planner that helps me navigate the various maturity dates and interest rates of my (15 due in 5) mortgages so that I gain the best financial advantage when paying down principal balances. 

Home equity is the difference between what your house is worth and what you owe on your mortgage.
