Yup, bought a townhouse, and paid a premium because the finishes were very nice, and everything looked good, even passed a pre-purchase inspection by someone with a lot of industry experience.

The tub leaked three times and ruined the ceiling in the dining room each time. The shower wasn't properly waterproofed, so that was a $35k rip-repair-replace. None of the furnaces had proper condensation drains, so my upstairs neighbour's A/C unit dripped condensation into my hallway for 4 days while we were on vacation, ruining the walls, causing mould. Our unit's A/C was mismatched - the outside unit didn't match the inside unit, and for 4 years we were constantly repairing it, until I spent $12k to replace it. There was a bunch of other small shit, but if I ever lay eyes on the builder, I'll punch him in the face.
