I will be moving to another state this summer, and plan to rent out my house as a MTR.

One of the homes is move in ready, with very little potential for value add due to the awkward layout and limiting lot size

You don't have enough equity to sell, so stick it out and make a strong effort to buy down the loan enough to sell and move on.

Most lenders have seasoning requirements, so you would need to own the property for 12 months to obtain a loan based on appraisal rather than lower of appraisal or purchase price.The longer the period of since property purchase the more likely an appraisal higher than purchase price.The exception may be a "hot" market where prices are moving up sharply almost every day. 

Still lots of people and companies moving here. 

New central AC with heat was installed in all four units each time an existing tenant moved out.

I would equate it to managing yourself when you are not set up to manage properties.There is scalability in this...Now to play the Devils advocate if you get autopayments set-up you can always figure out how much interest was paid each year and what your payoff is so just decide how competent you are in that and be honest with yourself, there is nothing wrong in outsourcing parts of your business.

Hi all, we recently moved an investment property under our LLC.

Can I just tell them to move out with advance notice?

First thing that came to mind is: given portion of lot is owned by "community" if HOA decides to move forward with $6k charge shouldn't that be dispersed across the community as opposed to just me?
