As Tony says, that damaged roof in the galley looks to be coming from what looks like a mushroom vent, with no corresponding hole in the roof lining. If that is the case then the leak should be easy to fix but that whole roof lining section is probably going to need replaced.....I imagine it's been leaking for some time. This arrangement is another clue that work done on the boat is sub standard.
Also looks like the engine bilge has had about 6 inches of water in it up until it got sucked out for the photos.
But in this price bracket these issues are par for the course, and I imagine more serious issues await below the water line. I love how the advert mentions it was freshly blacked in 2021.....only 4 years ago!
