When things function properly happy tenants that stay are what every landlord wants.

It's going to be a long list & it will change as a function of the type of finish or end use for the property. 

Not to mention just to make the project go quicker I refinished a 3 seasons room myself , fixed a patch on the roof, installed and painted front door, replaced French doors with sliding door, did some demo work in kitchen in bath, installed hardware on doors all things that were included in the scope of work ( he did a poor job estimating the price for renovation and I think was shocked when I wanted certain things fixed that I figured were common sense such as a non-functioning French door leading to the 3 seasons room).

Non functional essential lighting (e.g outdoor fixture doesn't work), floors that are trip hazards are good examples for this.

We also had my personal Heat and Air team come take a look at the system to make sure it was fully functioning and without any leaks.

Because paint is one of those things that needs to get done more often with tenants than it does for owners (we're talking function here, not staying vogue), I would suggest not painting anything.

If you are only using it for one of those functions then you are only getting a portion of what you are paying for.This isn't legal advice, just my opinion as a real estate investor.

Obviously you would replace or repair what isnt working but what about outdated things that are still functional?

A properly run business can not function in this manner but, aside from the concept of real estate  investing being a business, most prefer not to see it that way.
