I'd check with my attorney, some states limit the dollar amount that an LLC can be liable for, so at a certain point the cash and equity controlled by your LLC might be irrelevant and one or two could be plenty. 

The idea is to be able to control a property without using funds which are being reserved for investing projects. 

This is total Pareto Principle.  80% (or more) of your time will probably be devoted to placating him over this minutiae.Honestly, you've let him take control and it's time for your to reassert yourself. 

All that being said, you can actually take control of a property and drive results yourself, unlike the stock markets. 

Another option: leave it in place but put a low-boy in there with removable panels.

There is a property for sale that has solar panels and I’m trying to analyze at what price point would this or another property be worth house hacking?

They control the timing and have direct access to all parties involved.

If it is local you have control, you can self manage, and you have experience doing refurbs etc.

My old tenant moved out and he never complained about a minor issue a loose knob , my new tenant moved in and it seems to me like he wanted to take control the hard way by using a plier and that worsened the problem it can cost upto $200 just to call a plumber , I will try to see if there are any diy solutions.

Peace of mind goes a long way for a lot of people, and it’s not worth it if keeping the debt is going to cause you extreme stress/worry.Personally, I believe you could leverage a real estate investment to help you take more control of your debt down the road, creating another income stream.
