What to Tell Buyer on Fixing This Badly Cracked Brick Wall w/Pic?

[Burt L.]

I have a house to wholesale that has this badly cracked wall and has been scaring away the first buyers. This house originally had a carport here, that a prior owner had it "bricked in" and a bedroom and laundry were added inside this wall.

The ground visibly slopes toward this wall from the house next-door by nearly a foot, which is uphill from this house. It likely needs a French Drain, as I believe they are called. I don't see cracking on the foundation underneath this wall, though there are some older cracks on other unfinished basement walls but this crack is fresher as shown by the paint being opened up since last painted.

I don't know how these repairs are done, and if the entire wall has to be torn down and rebuilt or not. With a  repair, I supposed it could be trimmed out and covered as there are no windows on this end of the house. Everyone seems to run when there are cracks, though some more experienced investors seek these out, due to discounts.

What can I suggest to buyers that this wall that was a bricked-in carport, will need for repair?

@Burt L. my guess is that there is no foundation under the wall. It was just set on the edge of the carport concrete. The movement is from water or frost or both. 

My advise on an issue like this in the future is to find a local structural engineer that specializes in residential and pay them a consulting fee to come look at it and give you a verbal report. Should be a couple hours of time at the most. Engineers get expensive is you need to pay them to prepare a written report. Verbal consultations should be best because they have zero liability and you get the same answers. If you need to sell it then that is when you get the written report.
