Taking property management in house

[Mike A.]

We have a few properties about 150 miles away, so we currently have a property management company that is managing the buildings for us. We recently switched over to Appfolio for our buildings we manage directly, and I was thinking of taking the property management in house with the other ones as well. They are technically already in the system as they submit payments directly to us, but we do not like the way the property management company is working; and this is our second one.  They can open up a support ticket through the online ticketing system or call a toll free 1-800 number to page us and someone would reach out. We then call in a service technician and have them contact the tenant to setup a service call; which we pay for. We'd keep a realtor on to fill the vacancies, but we'd save 8% of the property management fee as well as any BS charges they they charge us. The biggest issue we have is they cannot produce original receipts, so we have no idea what is a real charge or an upcharge. They just claim they pay their contractors by the hour. It's just strange when we have charges for 100, 200, 650, etc, and they have no proof to back it up.

Does anyone else does this?
