Basement wall cracked - potential structural issue?

[Yvette Chung]

I am currently under contract for a duplex and just recently had inspections done. In the inspection it was discovered that the house may have structural issues. Inspector explained that there is a horizontal crack in the basement wall.

I'm quite worried about this as everything else in this property really checks out. But structural issues could be a big problem especially since I'm a newbie.

Has anyone have this issue before? Is it a very costly fix?
