You will want to consult with a lawyer.In regards to your last two questions here's some background on what makes a contract valid and enforceable:Offer: A promise to do or not do something within a certain time period Acceptance: A clear and direct statement that all terms and responsibilities are accepted Consideration: A legal and adequate inducement given in exchange for the promise Capacity: The parties to the contract must have the legal capacity and competency to contract Awareness: A party must be aware of the contract Legality: The contract must be legal in the jurisdiction it will be operating in***Not legal advice*** Steps I would take: -Review contract in detail to understand each counterparties responsibilities (if you are not aware)- Email a copy of the lease to each of the tenants listed on the lease and reiterate lease expectations for termination notice, rent payment etc. - If the lease was signed via Docusign (other esign may have same ability) - you can go to the envelope, go to history and view the IP addresses for each action taken.

Then when I exercised the option within a few months.

Once they exercise seller financing, the property is sold and all 1031 rules apply. 1031 has specific timelines.

That clause avoided a lot of headaches when the seller eventually exercised their option.Seattle permitting can really be a curveball.

You and the other posters here have been generous in indulging me in this exercise of considering this "partnership" / BRRRR, but demonstrating that we can invest successfully on our own power before seeking out partners is not only my strong preference but just sound business logic.As a new investor my head starts to spin when I start to think about investing, and the many gaps in my knowledge reveal themselves: how to structure a partnership?
