BUT.... if a person is an ready interested buyer, ok, that changes things, that resolves that issue for enforcement. 

They found a tenant in less than a month of the property being ready and quickly resolved the small issues the tenant had shortly after moving in.

Quiet title is a procedure for notification to any potentially interest parties to put forth any claim they might have within a certain period of time; and if no claims are put forth or if claims are put forth but the court finds no merit in them, then the court will affirm title and the questions related to validity will be considered resolved. 

I hope you get this resolved.

However, it has taken a long time to resolve, and ultimately, we both decided it was best to let the contract go.

Awesome, I'm glad you were able to resolve the problem.

They want stellar performance on: 1) listing, 2) screening, 3) leasing, 4) inspections, 5) maintenance, 6) lease enforcement, 7) communication, 8) liability mitigation, 9) tenant management, 10) market trends, 11) technology, 12) move-in / move-out process, 13) handling/disposing of tenant property, 14) resolving disputes, 15) vendor relationship and management, etc. 

They can get you straightened out and the situation resolved as quickly as possible. 

It’s important not to let things escalate, and the police will either be able to diffuse the situation or resolve it.

You will get this resolved and get to move on with your life.too bad at the loss of the $50,000+ down payment though.
