So I'm looking at a property that I may want to purchase, a slab-on-grade brick house in Cleveland, Ohio, built in the 1950s, and the floors are wavy where they meet the slab. Not by a ton, but fairly noticably so. Normally this would make me run away, but there is absolutely no separation in the bricks (or any evidence of tuckpointing to hide separation; those suckers are in the same place they were when Eisenhower was president...), nor cracks in the walls/ceilings, and the yard and sidewalk out front share the same kind of wavyness. This wasn't cited on the muni POS, so I'm wondering if this sounds like a broken slab or just a wavy grade. Any info or advice is appreciated, thanks!
