What probably happened is she didn't screen her managers properly, hired a bad performer, and then fails to admit she played a role in the whole fiasco.There are Landlords that claim all tenants suck.

Take online payments, market properties, screen applications, track maintenance, etc.As you grow and gain experience, I recommend you test drive the different platforms to see which one works best for you and your needs.

Issues will still come up no way around this, it's how the PM fixes the problem that makes them good.When talking to PM ask them how long it typically takes to place a tenant, what their screening looks like, how they handle service calls.

Have them sign all the necessary rental agreements and forms, hold them accountable to pay their rent on time, screen them if you'd like, and charge a deposit.I just ask for first and deposit + fees.

Start screening properties.

You will not learn you market sitting behind a computer screen.

This is also the first one where I want blood.

It sounds like you'll have an easy time getting the property rent-ready again, but you need to do a better job of screening and monitoring your tenants. 

College kids can always be a risk, I would have to screen them very well.

You screen applicants, you reject those that do not qualify.
