I was thinking to pull O&E reports, but it seems O&E report does not include these government liens and HOA liens, so it is probably not worth it to pull O&E before tax deed application?

This fee shows up for my rentals as a legitimate management fee on my schedule E. 

I'm in the same situation, the rental will go on your Sch E and you'll get your standard deduction for expenses,  plus depreciation. 

In fact we only have about 10 months experience managing 1 VR (Vacation Rental) which is a cabin in E TN.

If they aren't educating you on the rules like @Daniel E. explained, you could be playing with fire.

Message your e-mail and I'll share some great contacts.

E-myth is another good one. 

Posting on Facebook is most certainly marketing, but even e-mailing a deal to someone in private is marketing.
