If you have enough stock that you don't need to sell all of it you could try to find a brokerage(you would have to transfer the stock to the brokerage)/bank willing to loan you money on the portfolio. 

Now I suppose bad reviews is always a risk of working with people, you try to do a good job and hope people are satisfied, as for the 2nd thought yes this is something I absolutely need to do more legal research on and check with my brokerage, my thoughts were this would hopefully be covered by a standard buyers agreement, again if you take a 2.5% commission and the person hates thier house they can’t sue you, I would hope this would be the same.

You will typically be hard up to find a brokerage that is an MLS member but not a Realtor association member.
