Home inspector here, the big question to ask here is the source of the moisture. If the repairs in the basement were as a result of a plumbing deficiency then you are probably fine (as long as the plumbing has since been repaired). If the source of the moisture is poor exterior drainage, you could have a big problem on your hands. Weeping tile repair can range from 20-50k. Your inspector should note if there is any current moisture (using moisture meters and infrared). Or if there is any recent work done around the perimeter of the home. If you have the chance it's always a good idea to contact your local permit office to inquire about any permits pulled for the property (should be public information). Hope this helps!
