*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).

Sure, it stinks to have to pack up and move, but if you are being overcharged the answer is simple- move to another apartment.I think what many tenants find is that although they may have a large rent increase, it is still far cheaper then market rate.

It's gotten to the point that my tenant is now accusing me of misleading her, saying I "took advantage of" her and am overcharging for rent.

He will over charge  your credit card and when you call him out on it he refuses to call you back or even  email  you!

I always assume the landlord will be fair therefor never allow the tenant to be involved with or negotiate anything with the landlord.Unfortunately most tenants have no concept of what anything costs therefor will always assume they are being over charged.
