Is there a dollar amount of expenditures you want to require unanimous approval?  

Personally, I'd go for a condition that says unanimous agreement is required to do something with the property.

@Joel Owens, I think you are referring to Unanimous Consent for the TIC deals. 

@Ross Trampler, It's unanimous. 

Seems to be pretty unanimous agreement on that.Let me phrase the problem in different terms:What do you do, as an real-estate investor, when you realize you made a SERIOUS error/miscalculation and are now stuck in a very bad investment situation?

According to this site they've extneded to 2018 https://www.portlandoregon.gov/bds/article/569789On April 13, 2016 City Council unanimously passed a Resolution extending the current waiver of System Development Charges for Accessory Dwelling Units.

For example, you can have a provision that requires any expenditure above $X,XXX be approved by the unanimous consent of the members (you and the partner), but that anything below that threshold can be done by the manager (you) (e.g., purchase of fixtures for the house, payment of subcontractors, etc.)

I think we all unanimously agree that the request to remain a tenant is the main red flag.

We provided all articles of incorporation and an unanimous consent from board of directors stating that the company was authorized to purchase the property and procure funds for purchase from my partner. 

Courts have unanimously ruled differently.
