I buy tax liens in that area and your description of the creek and defunct golf course led me right to the listing via Zillow. 

This would be the most turnkey option.It gets a lot more involved, I can answer any specific questions you have about the pros/cons of each or anything else.I ran a brief basic search (snohomish county, 5+ acres, SFR) and there are properties that meet that description that have a open NTS.

based on your description I too would agree with Fishtown.

How do you find the legal description of a property to use when filling out a contract?

That description appears to be broadly applicable to "real estate education".

It basically contains your name, sellers name, property and dress and legal description, your offer price and the terms including contingencies and timeframes etc.If you are pretty sure you’re going to move forward you can get your attorney to just draft a purchase agreement and save a bunch of time if it’s a smaller purchase.

@Jason Bajaj, Based on your description of ownership length and use the property certainly qualifies for 1031 treatment. 

These definitions are generally descriptive not prescriptive.

I was measured and honest in my description of my experience though and I do believe that they bit off more than they could chew.

@Jimmy Lieu's property descriptions and due diligence are thorough; can confirm bc I'm on his mailing list hahaha.
