If you are hell bent on owning this condemned property, have her deed you the property and then, since "she wants nothing to do with the property" she can be legally free from any obligations.

Also are appraisals always required I know that some companies used BPOs.

While I don't have enough experience with either company to say one is better or worse for hosts than other, I've always found VRBO to be the far clunkier and less user friendly by miles.

This property has been so hands off I have not thought about in years like I should have and i do NOT have the time to educate myself to say the least (I run a company). 

Multiple, billion dollar companies are investing heavy in our area, such as Intel, Google, and Amazon.

So for example, here in Greenville, South Carolina, we have major auto manufacturers, BMW, Michelin and a whole host of smaller companies that manufacture parts for these larger facilities at BMW and Michelin.

The squatters would have to go through the legal process, which they won't because they know they have no evidence of legal occupation.The worst that could happen is violence, so you should only attempt this if you are prepared to defend yourself. 

Will an LLC or Trust help with legal protection?

I guess the other option is to use a property mgmt company to find a tenant for you, but I just thought it would be interesting if there's a site where the landlord can peruse a list of quality tenants and reach out to them directly! 

Does anyone know of companies that have acquisition managers that they can place with a small real estate investment firm?
