Would love more capital to keep expansion the other two sites too. 

Though, keep in mind that HELOC rates can fluctuate with the market, potentially exposing you to higher interest rates down the line.On the other hand, a cash-out refinance could lock in a fixed rate, providing stability/predictability in your monthly payments.

It'd be great to have some people physically around me to keep me accountable.

Those jars/bottles can still get gross, and it ends up another item in a long list that you have to keep up with. 

Again, proving my identity is different than them keeping my ID on file.

It can be awkward having to tell them to keep it clean so you just set ground rules in advance.

I would not be eligible for a 1031 exchange, and when looking at refinance rates on 3% and 5.5% rates respectively, the numbers would not make sense to keep the properties and scale. 

Keep up the great work!

My concern is that I do not want to keep replacing the "ejector pump".

Keep saving as much as you can.
