Scott, thought this might be interesting for your company and for use in your training and such.. 

My company provides a comprehensive A-to-Z solution tailored to our clients' needs.

I have been using comps from the MLS but as the company grows, I dont have that advantage in other states.

I’d love to hear about the crime rates or any other issues (which we cannot guess from the online stats), and how easy or hard it is to find reliable tenants and property management companies.

It is not legitimate and I do not legally owe this balance, but have been unable to get it removed from my history unless I file suit against the company.

And when the company you're suing has shut down and apparently has no money, is it even worth the effort?

It may sound nice to pay a 6% management fee but the extra fees can add up to be more than the other company that charges 10% with no additional fees.

Or suggestions for other companies that provide a similar service?

In my case, I have residential rentals in one LLC, commercial properties in another, self storage in a third, and my real estate company operates in a fourth.

Larger company -- tried to escalate to the owner.
