Hello buyers in the Spokane, WA area and the PNW!

Make the place nicer or lower the price to get bargain shoppers. 

My endgame is to end up with $300k/yr in post-mortgage income in 20 years based on investments I make now followed by continued investments over the next 10-15 years own.

Talk to the exterminator and let them know there is a problem. 

Why not test the market by putting the lots up for sale, and if nobody bites, that might provide your answer. 

@Tramaine Robinson I can’t pinpoint a moment in time where it “clicked,” but instead I’ve found a series of small victories that yielded improvements.My first profit gave me confidence.  

How you use the equity will be important. 

Also, I am guessing that due to the state of the house, it would not qualify for a conventional loan?

Your suggestion to list on open market likely is the best option for the OP.  

But keep in mind if your using money you cant afford to get back then buying action property might not be appropriate for your current endeavors and its better to just buy open market were you can do proper due diligence and know you have a build-able site.
