You should only sell when the opportunity comes up to invest the money into a better investment vehicle.

It might make more sense for you to go to some traditional investment vehicles first and start your RE career further.

Current retirement portfolio includes reits in Roth vehicles.

Things like people needing a jump start, a flat tire fixed, being locked out of their house, borrowing a boat motor, providing deer processing equipment, fax service, finding a place for their girlfriend when their wife shows up unexpectedly and sending/receiving packages are things I do for my tenants regularly. 

Finance vehicle is the LLC installment operating agreement if I understand correctly I'd have drawn up by an attorney.

I have a Commercial Lot that I will be leasing to a company I own for Vehicle Storage in El Paso, Tx.

As long as you can comfortably pay back the HELOC, it is a way to get started.Instead of borrowing against your 401k, talk to a financial adviser about how to roll it over into a self-directed 401k and use that as your investment vehicle

You don't have a vehicle but can temporarily borrow one every other day temporarily (so no uber or food delivery).
