Too wet is a boat that is still leaking. If there are wet spots but the current owner has taken care of eliminating/minimizing the intrusion you are in ok shape provide the wetness is minor.
Wet spots to check:
Bulkead near chainplates
Cabin top near secondary winches
All in All the J/30 is a very solid boat and they are basically all wet in some fashion but that does not mean they are not sound boats.
Good luck hope to see you here as an owner!
