Hi N.,
I would contact a home inspector to start with. They will be able to lead you in the right direction.
I know in Illinois they're regulated by The Office of Banks and Real Estate (I'm an appraiser and we fall under the same regulatory grouping. Try the Ohio site and do a search for inspectors. You can ask for their license number and do a search on their sight to make sure they are up to date on their liscensing and have no negative judgements or issues linked to their liscense.
Good luck!
