At this point I would put your PM on notice that you are going to go by and inspect in 45 days and if anyone is on the premises that is not named in the lease agreement you will be forced to terminate their services.

The main issue that I have is that the tenant has 2 more years left on the lease and in order for me to fix all the mess in the basement I would have to remove tenant. all plumbing, electrical and structural is potentially dangerous.How do I manage repairs if tenant doesn't want to move?

propstream or some other list service filter and make a list use a list service to contact owners via cold calling, mail marketing, texting etc Once the owner is contacted, get the condition of the house, pictures and get a contract signed 

But whatever you decide (professional maid service, hire someone specifically and train them, your spouse, your nephew, assistant) make sure whoever is cleaning knows EXACTLY WHAT YOU WANT THE PLACE TO LOOK LIKE WHEN THEY ARE DONE.

The opportunity for positive cash flow after quick repairs.

To me, owning rentals directly was more work to manage my manager than it was to manage the rentals (and I was making less money due to management fee and inflated repair costs).Syndications: you need to know how to really read people, read financial statements, and understand many of the risks of real estate.  

Does this service exist?

It needs little repair/work as the owner is a contractor and his daughter initially lived in the home, so he's kept it up-to-date.

It is a very difficult area to operate in because of limited service providers, home quality, and the increase in supply, and big drop in demand. 

Investors are not the only ones that have taken notice of increased STR supply, the majority of the cities, counties or jurisdictions I service have recently implemented new or revised regulations for obtaining and operating a vacation rental throughout the Oregon Coast and area of coastal California.
