Next time you are there, check to see if the Pergo is buckling/peaking a bit at the seams--that's a sign of moisture.If this is to be a rental, I'd completely rule out carpeting and look at vinyl planking--it's water proof, and easy to maintain and repair. 

So technically I can hide some of the income under the carpet, at least I hope so.

Three years ago I got this bright ideas to remove the carpet in my condo.  

So my gut feeling just based on what you said would be to get it "freshened up" (6 panel doors, some nice paint, replace some carpets, remove clutter, heavy cleaning, clean ducts) and get as much as you can out of it.

After your story, if the existing floor underneath the carpet is in decent shape I'll be trying it out. 

For instance, there is 1980s terrible green-colored carpet in the living room - does it make sense to replace that? 

The tenant had a cat that used all of the carpet as a litter box.  

After living in our 2 story 3 bed 3 bath home for 12 years, we found that while moving out that our home needs paint, carpet, new flooring in the kitchen...etc.

My PM told me that they cannot take care of the house any more, the dogs pee inside, The carpet needs to go, the concrete needs to be treated.

Other minor cosmetic work may include new light fixtures, switches, and outlet covers, carpeting removal and shiny hardwood floors.
