If you don't have VAs or don't have other owners involved, it might be all you need. 

After multiple calls and emails about the matter (even involving the local HUD office), I finally get a response that says "Unfortunately, HACW is experiencing a temporary shortfall of funding and will be unable to pay the HAP amount for this month..."

So getting one involved now and sooner rather than later is a great move on your part.

They did not communicate the scope well to the plumber, who it sounds like should not have been involved in the first place I would have a point-blank conversation about the above with your manager and ask who he or she thinks should cover the waste of paying multiple professionals to shuffle a thin plastic piece underneath an appliance the tenant was responsible for installing in the first place.

That would be nice, but I suspect that I will somehow be involved in it...?

Then when things go to hell they walk away and pretend they had no involvement with the Property Manager even though they facilitated countless transactions positioning themselves as the owner.

I have my eye on a couple of small places that I am interested in for Air BnB.  

Just make sure to check their credentials and experience, and find someone who can explain things in simple terms.Also, keep an eye out for any red flags, like promises of huge refunds without a thorough review or pressure to pay a percentage of your refund.

Understand the fees involved and calculate the total cost for an entire year of management so you can compare the different managers.
