Thank you so much to everyone for your responses and help! I called the Register of Deeds today and found out that it was purchased in 1993, before Affidavit of Affixture was required, or maybe even before they existed. So it is not affixed to the property. After that, each transfer of title did not have a mortgage, so it was never an issue. So they referred me to the Secretary of State to inquire about the title and how that would work. SOS told me that I could request the history via a form (BVDR-154 for anyone in MI researching this down the road) that has to be faxed in, then they mail history to me. From there, I would have to try to contact the person, likely a next of kin because the original owner's deed transferred to his estate. In the meantime, I would need a surety bond for double the value for 3 years that protects me. She wasn't clear on what would happen after that if contact isn't made, but recommended I talk to an atty about that. I'm not quite sure if I will still bid on this, but I sure did get an education! Thanks again everyone for the input!
