I know absolutely nothing, but that's not just a crack, it's a displaced crack. If the condo has sticking doors, take a pass.
I'm having my foundation done tomorrow. It's only off by a little, no interior cracks, hairline step cracks in two places with the bricks. They'll be doing 12 piers for $4600. Your mileage may vary. I looked at a house before buying this one that had 16 piers for $10,000.
