Can I trust the person that is representing me?   

If you buy a house for $300k through an agent, you don't pay any fees on top of that $300k.Now, the smart thing to do if you're browsing Redfin for property is to reach out directly to the selling agent and, after discussing the property and demonstrating that you're a serious lead, offer to let the selling agent also represent you as the buyer.

Your agent has a fiduciary duty to YOU, and you alone unless he/she is also representing the buyer. 

The Gap represents just that, the gap between percent sold and percent expired. 

I understand as a Wholesaler, I’m not representing neither owners.

I don't see any issues with this arrangement- since I'm not representing anyone, there's no agency created, therefore there's no risk of violating a fiduciary responsibility.

Just like the money represented in those chips you waved good-bye to in those 5 lost hands, the money you waved good-bye to in this first deal isn't lost...it's just in a different property...the next one...which you can get back, as long as you are "still in the game". 

Should we hire our own attorney to represent this case?

All assets would be title in the name of the custodian, something like this: ABC Trust Company, FBO Chauncy Gray IRA 1234567 (the numbers represent account number).

Just to try to be clearer, currently I am not concerned that their water heaters will leak and flood the unit I want to purchase (they are a floor down from the living space), but that because the only access to their water heaters would be in my unit, that I could some how be responsible insurance-wise or legally.The seller of the unit represents his mother (who recently went into a nursing home and cannot make her own decisions).
