I responded to your new property management company's request the very same evening and handed over every piece of documentation I had on your tenant. 

Firstly, the people telling you to go ahead with it will not be there to pick up the pieces if it falls apart or is a daily headache.

There is always local artists who would be happy to provide pieces for display if they could make some sales.

I have been in the contracting business 35 years , and the ONLY contractors that work without supplying materials do piece work for track builders .

I'm looking for feedback on what distinctions need to be in a lease like this.

Whether is taking his "course", paying for the self written articles about his success or aka writing "puff pieces", buying fake Instagram followers, sitting on FB marketplace trying to get someone to pay for a house they don't know is condemnable and pay to have DJ remodel it and DJ never completing the remodel,  him spending an enormous time defending himself in small claims court, and threatening charges on  people that don't know law so they pay what he wants.All of those examples came from either my observation, experience, or other peoples reviews of him.The guy rented me a condemnable property.

@Blanca Munoz  A very important piece of info for relevant feedback is how much do you owe, if anything, on the property?

Two people own a piece of property and are wanting to do something with it - That's a partnership no matter how you slice it.2.

My brother and I would like to be co-owners to the new property but our contribution to the purchase of the new home is by way of investment loan, so let's say my parent's home sells for 500k and they want to go in on a $1M piece of property.

Maybe you could bring in a partner on this deal for a piece of the action.
