In a traditional seller auction (non-foreclosure) the properties are sometimes occupied by the seller themselves or a tenant. The Auction Firm will be able to provide details and, if tenanted, a copy of the lease.
For Private Selling Officer Auction, we do not know as we do not have access to the property. Keep in mind that you cannot trespass or disturb the owner or occupant. Doing so may be a violation of Ohio Revised Code Section 2911.21, which provides criminal penalties for trespassing.
