For example, there is no incentive to do a fast and quick touch up paint over charging for repainting an entire room -- in fact this may not even be possible if no one kept records of the brand/color and finish of the original paint.   

We gutted a unit and hired an electrician to install new can lights, rerun all the electrical in the kitchen, install a larger breaker box, etc.  The company is run by the owner and he has 4 electricians work for him,...

But they do charge and over charge for mowing,repairs and turnovers. 

@Jacques Villars 2% can exist in rougher areas with S8 vouchers and tenants who can contribute additionally to that rent OR if you are close to a military base or university where you can overcharge students

*Hiring an expensive contractor who overcharged for everything, did an OK job, but left a few things unfinished and has refused to fix a few mistakes his crew made.

Over charging for services or being lazy when finding cheap solutions is a constant problem.

Overcharging, and often actively defrauding you month 4 and on.

And the bigcorp rental owners have been significantly overcharging on rents for a while too, at least for 2 years since I’ve been watching them. 

Either they know what they are doing and just overcharging you, or, they don't know what they are doing and you are paying them to learn.

I can’t speak for anyone else, but my bad feelings towards landlords stemmed from entitlement on their part - overcharging, failing to respect boundaries and general intent on service to self rather than being considerate of my needs (Ie treating me like a p&l instead of a fellow human).
