Because I have questions to ask before giving out advice so I know which to share depending on the individual needs and solutions that have not already been explored.   

this looks rough. really rough. cut down trees and pressure wash. or else the look will come back in 1 yrwish you nothing but luck simply because you jumped in!

Better to spend the money for someone to look and give you a answer or the cost of a solution to better judge what you should do.

I have ~$150k tied up in this that I'd like to use for buy and hold residential but it feels like I'm trapped.Anyone have any creative solutions to end my pain on this one?

As far as Distressed sellers go as soon as you get the information call and discuss their situation stating that YOU have possible SOLUTIONS to their situations .
