I agree with @Jorge Poveda and @Van Flowers.  

In this case I would negotiate a fee arrangement and not tie it to profit.

This will be a house hacking arrangement.  

I just commit to agents that if they show me a property and I want to buy it, I'll submit the offer through them.When you get out of your exclusive arrangement, I'd be happy to help you....whether it's to submit an offer on the property in question, or to find another one(s).  

I confronted her that I don't feel comfortable with people entering my home when I'm not there because of my valuable possessions and my dogs, and that I'd like the 24 hr notice so that I can make arrangements and also make sure the house is as presentable as possible, considering packing and moving will be taking place.

And if you want a Skype guest in the future, we can probably arrange something ^^

You come to Milwaukee, especially my side of town, and you'll see flowers in the medians, nice signs and fences, and no graffiti. 

I will have the sole and exclusive right to purchase the property at any time of my choosing for the nominal amount of $1 from the seller and whatever arrangement I might make agreeable to satisfy the relevant creditor bank's remaining debt.

It is clear that the optionee is the tenant paying above market rents.......another predatory matter and giving credits toward a purchase price is a financing arrangement covered specifically in Dodd-Frank!

I am also looking forward to the meet up arranged by @Charles Nguyen on 10//22.
