Masonry cracking - thoughts on severity

[Fedor Volkov]

Hi BP community, 

I'm looking for a masonry contractor, to solve this one, but in the meantime wanted to gather any thoughts on one home inspection item I just received yesterday. There is a masonry cracking in one of the walls in this building. Doesn't look bad from the photos, but would love to hear any "worst-case scenarios" that folks have seen on similar cracks. Could this be bad and result in a lot of costs to repair? 

Thank you!
