She will lose it.They are offering to pay off her $87,000 debt, they will remove the squatter, they will pour money into the property to ensure it sells for the highest value, and then they will give her an additional $240,000.She is getting $327,000 for a property that she is about ready to lose and it's probably affecting her mental stability and physical health.

Our company also offers full service property management, rehab, etc so a true one-stop-shop for OOS investors.

Quote from @David Eyal: This is actually very simple: don't get involved in personal issues.You offer them a renewal.

My realtor is also exploring options with their legal team, but extra insight is always appreciated. 

I am targeting homeowners with dilapidated homes that need repair and offering to pay for the rehab and split the profits with them at the end of the project after the sale of the home. 

I even offered to have them repaint the house in exchange for a lower rent, but they refused.

A signed lease is a legally-binding document.  

Collaborating with local real estate agents or property managers can offer valuable advice and support.Good luck!

I would not offer internet.

Also, Hostfully offers a nice digital guidebook.
