Did a light rehab on the 3rd unit - fresh coat of paint and new carpeting.

In reality, my flooring contractor (all hardwood floors) was able to sand the smell out of it - and let me tell you, you've never smelled anything like freshly sanded cat piss - and 98% of the stains, and put down 3 nice thick coats of polyurethane, and the smell was completely gone at the end and never came back. 

How is the rental demand in Doug Co at the $2,500+ price point? 

Painting or other protective coatings are the responsibility of the occupant, not the landlord when required more than once every three years, as a result of acts or omissions of the tenant.

@Anil ThomasThat cost seems about right for 1400 sf for sanding, restaining, and poly clear coats. 

You're wearing a white coat in your profile picture, so I'll assume you are a doctor.

It looks better with a coat of paint.  

The best write up I have seen on the topic is on a website called White Coat Investor.  

The thing is, insurance is only retroactively and doesn't keep you from getting vandalized.In marginal neighborhoods they'll watch you and they'll not only take water heater, heating system, plumbing (if copper), but they tear open the wall to take the wiring (which they'll later put in a little bon fire to burn off the rubber coating) to sell for copper.I would suggest for you to either get a wireless, monitored alarm system , which can be a deterrent in the first place or see if a company like this is in your area , who covers windows and doorshttp://www.vacantinvestmentprotection.com/
