do these cracks look like a deal-breaker? (masonry)

Hi all, i'm getting ready to close a triplex in Sherbrooke, the inspection turned up quite a few cracks in the brick though....like the building leaned slightly to one side a while ago (although the foundation is solid). the current owner says the cracks were there before he bought it (over 20 years ago).

just wondering what you think, i will probably ask for a price reduction, maybe $3000 or something...how much does it cost to repair brick, anyhow? i assume good masonry isn't cheap. thanks!
