I'm not endorsing Evernest in particular, because I don't do that. However, I do consulting work for a great many property management firms across the state. It is hard and it is complicated. It is not a 9-5 job, or even a 7am to 6pm job. Lunches are often taken late in the day or not at all, because most prospect calls come during lunch.
It is a balancing act between what is legally required under a lease and what is needed to keep a good tenant who has a temporary problem. Not only do you have to devote time to property management, you have to devote time to education in ever-changing laws and financial metrics. You have to know enough to stay competitive in amenities and software tools. You often have to make split-second decisions without complete information.
EVERYBODY has problems keeping and retaining employees, so that is another challenge, which usually requires greater investment and self-education in technology.
All landlord and tenant issues have to be evaluated and balanced among those that are important but non-urgent, important and urgent, and urgent but not all that important.
As a landlord, you are part of community that shares your property manager's time and resources with other landlords, without being privy to the decision making regarding allocation of scarce resources. Sharing doesn't always turn out the way you want it, but it sure beats doing everything all by yourself. Especially when your own time and attention is diluted by sharing with family, friends, community, finding additional investments, perhaps a "day job," etc.
I find that communicating unhappiness or frustration with the person in a position to address the situation is usually the best course. That should be followed by an agreed plan of action with deadlines and follow-up. That should all be in writing. In my experience, most problems are solved after that.
