Christine you need to talk to an attorney. In Ohio land contracts are a little strange having to do with the equity percentage provision written into state law. If thebuyer has over a certain percentage of equity then it is a forclosure. If they are under that percentage other legal rules apply. You may want to call Griffin Fletcher & Herndon LLP ask for Harold Anness. If he does not respond to you in 24 hrs after your call you can contact Amy Gregory she is his processor and will "light a fire" under him.
Their contact number is 513-421-6440.
