Problem Tenant in Wholesale Deal

[Derek DeVerna]

I contracted a property here in beautiful Toledo, Ohio over the weekend. The lead came in through a direct mailing campaign that went out last week. The seller lives out of state, is behind on his property taxes, and just wants to unload this house that he inherited five years ago. For the last 4 years his nephew has been living in the property rent free. Needless to say, this has had a tremendously negative impact on their relationship. 

For this reason I was unable to enter the property before placing it under contract. This does not scare me, as I have an inspection period on the contract and was able to leverage the lack of access to secure a very cheap price on the home. The owner was kind enough to supply me with his nephew's contact information, but I have not had any success in contacting him. 

I typically offer "cash for keys" in this situation, as I can usually get the tenant out of the property for less than an eviction costs. However, if I cannot get ahold of the tenant I obviously cannot make a cash for keys offer. Would it be in my best interest to try knocking on their front door and introducing myself? Or should I just plan on filing an eviction? Any insight or personal experience would be greatly appreciated. Thank you kindly.
