If the paint does test positive, you'll need to follow regulated procedures to clean it up (or contract it out).  

Items completed:Kitchen has been cleaned, updated cabinet hardware & painted.  

And if the ducts are old I can get them cleaned, no big deal.

I want to clean it up, get good renters in there and improve the look and value of my neighborhood and have it as part of my retirement portfolio.  

Your question makes me want to check my state rules (Illinois), because I've thought many times that I might as well manage other people's STRs if I have all the processes set up to manage mine anyway.Finding a cleaning crew for 1 STR is difficult, but 5 is easy. 

It steam cleaned up great between turns.

No grout to remove and regrout when it get moldy when tenants dont clean and maintain.

The window trim could not be fully cleaned, so I replaced the window trim and made sure the bathroom was very clean.

Sounds like the classic living out their deposit scenario in which they will deplete everything and leave you with nothing to cover repairs, clean up and other turnover costs. 

I can clean up and do the smaller jobs myself.
