Hi Daria
I had something similar. I too rehabbed a house; completely, from top to bottom. I also had a property manager who charged me for every single visit.
I advised the PM that the house was recently rehabbed and there should be no problems with electric, plumbing, roofing or anything else. However, if something did come up and she got a call from the tenant, she should call me first before going out. I would then call the contractors myself to go to the house and meet with the tenant. This was a transitional period and if there was an issue, her handyman would not need to take care of it as it was all under warranty. After the first year, she could make repairs as needed.
She was resistant at first but i explained that this is what I wanted. Long story short....i no longer have a property manager and do it myself from 3 hours away. I have a list of handymen and professionals who i can call to go out to the house if anything is needed and they pay the rent directly to my bank account.
Good luck.
