Russel was one of the first members here I contacted 6 years ago when I was looking for fix and flip properties.

Examples of pitfalls include purchasing in an undesirable area, not understanding the market values (vs. list prices), not knowing the rental values (current and market), inheriting bad tenants, buying a lemon, going rogue on renting and management with no contacts / systems / no legal understanding of PA and Municipal landlord-tenant laws, not having trusted resources and contractors in place, using out of state lenders or shaky financing, throwing lipstick on a pig when renovating a house and wondering why it's ARV isn't increasing, tenants are renting, etc.

so after reading all the posts, it sounds like his best bet is just to move on and walk away finding another place maybe coming back in future to keep contact with that person if he really wants that location… Correct me if I’m wrong, but my analysis from all this is that hiring a squatter would only be applicable in situations where the person who is occupying the residence never had a lease or contract therefore it is a rare circumstance where it would be a viable option. 

Be prepared to use initial capital to get in contact with leads and market.

I suggest you contact each of your tenants currently renting at 721 to determine who all intends to stay and who is planning to leave.

Thank you I can connect you with the right contacts who can help you structure your LLC.

By resources I would be saying capital, contacts, soft skills, credibility, all of the things that help grow your business and start building a positive reputation. 

Where could I get in contact with someone like this and what kind of rate should I anticipate they would expect?

Shoot me a DM for their contact info. 

You may also consider contacting a real estate agent who specializes in STR properties and who has STR investments themselves in the area.
