My vision is to keep it a while (it’s paid off) and use the cashflow to help with my kids college.  

Meaning they went into a standalone bank account (not mixed with your other personal funds). 

Having a person answer the phone costs the PM company substantially more than operating a support button with a delayed response.

That could be you personally or an LLC. 

The property isn’t worth what he paid for it. 

What is the point behind having paid off real estate, if you lose it later in life to oppressive taxes?

The lot is paid off and deeded to our LLC, but lender will not do conventional loan to LLC for the remaining financing so we'd need to take out a loan in our personal names. 

Goal would be to acquire 20 rentals by the age of retirement, with some already starting to be paid off.I am in the same boat as you, and I focus on safe appreciation all day (small cash flow for safety and then focused on markets on that appreciate). 

But doing this we ran into a lot of crooks who once they realized they were not personally responsible for the debt just ripped rents and never paid on the underlying thereby totally fubaring the sellers..

While an LLC can offer liability protection and tax benefits, it’s not essential for a single property—personal liability insurance and an umbrella policy may suffice for now.
