20% premium of repair costs, $65 per hour for unlicensed repair work, really?

[Naga A.]

My property manager charges me with 20% premium of any repair costs when they act as general contractor to sub contractors.

On top of that, I received a letter that they hired an inhouse handyman for unlicensed minor repair work. They charge $65 per hour for such work.

What do you all think? Seems to me these charges are excessive, and give pm an incentive to have as much repair work as possible (in fact, there have been numerous repair works on my property so far.)

The property is old (built in 1958) located in Atlanta.
