I could be wrong there, but regardless I know developer pain when hands are tied.

Hello Jeff, Drew isn't necessarily wrong. 

Sorry, but you all are wrong for asking for the findings. 

. :)  they get fixated on the wrong things and never take action.

You have to make your personal decision, considering the time and effort it will take you to DIY it; the risk of it being done wrong, and the potential opportunities you might miss by not letting the pros handle it for you.The more expensive your property is - the more reasons you have to hire professionals.

While reading your experiences and thoughts, I saw I would be making the same decisions (and then I saw why they were wrong).

What exactly has she done wrong? 

If this is the wrong approach please let me know what you think is the right one. 

The manager by action or inaction could be sued directly or in addition to the property owner for a tenant or guest being injured.There is an additional liability extension called personal injury or landlord personal injury that picks up the liability for a situation such as being sued for wrongful eviction or violating fair housing in some way.

There’s nothing wrong with your plan even with the delinquencies, it may just take you a little longer than you would like.
