1. Lack of communication with me, their client. But I didn't hear from the tenant itself until when they were moving out and some issues, so I guess their communication with the tenant was good. I'm guessing they wanted to delay communication therefore the problems became "urgent" and then they wanted to use their contractors. They charged 10% fee of the total sub invoice.
2. Misuse of the $500 allowance for maintenance. They needed to notify me of anything over $300, otherwise they communicated whatever they feel and most of the time they even didn't bother to call me or email me of anything less than $300 expense. Then I saw the monthly statement and was overwhelming.
3. Communication with the HOA was a big issue. I had no help from them on any of the tenant's issues with the HOA. In fact, I had developed good relationship with the HOA management company because of this. So at least something positive.
4. Poor walk-in and "as is" documentation notes/report. Tenant at moved out took all curtain rods and drapes (valued at over $350), they never followed up. Explanation was "we have no evidence there were curtains in your property". But yeah, they charged me $100 for an in-moving condition report...
5. Lack of putting notes in their system for things I know about the property. Like for example that GFCI outlet that goes off. I explained to them the situation so they can communicate that to the Tenant. They obviously overlooked, resulting on an extra expense, which they replaced and charged me, and the problem persists. Electrician invoiced them with a new GFCI outlet, their time and everything, and with all that, the problem persists.
I can keep going, it is maybe my luck and experienced with PMs I guess.
I hope you do a better job. If not, you will have a lot of unhappy clients like me and a lot of turnover.
Good luck.
