@Thomas Moran, one of my biggest regrets about not buying involved a house with similar-looking cracks near downtown Durham about 8 years ago. The front of the house had a huge diagonal crack from window-sill height down to the ground. Some of the bricks were literally leaning outward. The interior was a basic reno, new kitchen and bath, and painting mostly. Asking was about $20K. I walked that house a half-dozen times trying to convince myself to buy it, but ultimately allowed my ignorance and fear to convince me to pass. I wasn't the only one -- it sat on the market for months. An investor finally bought it, pulled down half the wall and had it rebricked. It was all veneer. Probably cost him a couple of thousand tops. I shake my head and smack myself every time I drive past it.
Since then, I've seen several other houses in Durham with even worse cracking and separation. Each was a veneer problem, not a structural problem. Sometimes, the entire side of a house (the bricks only) have had to be removed and redone. That's not necessarily as expensive as you might expect. I've also seen structural problems, but those can be figured out by difficulty opening doors and windows in the rooms closest to the cracks, and of course, going under the house to check the foundation to see if the cinder block foundation is actually cracked on the inside, or if there is water penetration.
If you've been looking in Durham for a long time for your first buy and this one fits your other criteria, don't just blindly abandon this opportunity. If you don't trust your own ability to figure it out, pay a professional a couple of hundred bucks to take a look at it.
