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?
