Floors will get stained and refinished   Back yard and front yard will get freshened up along with a coat of paint for the facade.Budget is 20k

I'd like to meet the property management company and the business people(cleaning and handyman related) so I could paint a better picutre.Thank you for the info.

LL would have no incentive to paint, update flooring, etc.  

New furniture, coat of paint, and some minor rehab to the decking.

The solar system adds no value to my property for rental purposes, and I may even be ripping up the roof & replacing it in the new year.Beyond sending a nasty letter through my attorney via certified mail, demanding the company come pick up their equipment, am I required to take any further action or fulfill any obligations regarding these contracts?

We asked the owner if we could start painting the house before the closing date...

If the lines are aluminum, we ALWAY replace that like we replace lead paint or lead pipes and asbestos ceiling and tile.  

You are better off finding a solid property that needs light cosmetic work (paint, floors, or maybe even a kitchen or bathroom remodel), buy it at a decent discount and put 25% down or more (this is when you get best rate terms). 

A tall fence, tree, exterior paint can control a lot of things your guest see during their stay.

That hard work includes making the investments that the current owner hasn't made (nicer kitchens, new flooring, fresh coat of paint, etc.), removing tenants and marketing to new tenants.
