You need to read your state statutes ASAP and then take whatever action is necessary.

However, in the event of a lawsuit you would lose some or all of your statutory defences, and might even be successfully sued for treble damages under the statute of fraud.Utilizing a structure of purchase contract assignment would somewhat disguise the brokering activity, and lessen the threat of a lawsuit.  

The reason for that is that the statute is clear that your intent must be to hold for productive use.  

@Joseph Hamaoui, Since 1031 is a federal statute there are no extra hoops when selling in one state and buying in another other than knowing any particular state nuances when it comes to state taxation.  

I'd start with the abandoned property statutes.

Study the property code in MN https://www.revisor.mn.gov/statutes/?

I presume Idaho because of your location but plenty of people buy in multiple states.If the six( 6) month statute applies in your jurisdiction, your challenge is that you don't have an owner or estate rep with standing to provide you what you need to eliminate the right of redemption. 

Isn't there a 'statute of limitations' to payment disputes? 

Shoot me the statute number I would love to give it a read and make sure I am complying with all local laws and regulations.
