Question: Are you the lien holder on the title? If so, then you should have the title. If not, then I don’t know how you are going to reposess something you did not have in the first place.
Another question: Is the guy still living there or is the home vacant? If it’s vacant, can you offer to forgive all back lot rent and any late fees in exchange for the title?
I think you need to evict the home, attach a judgement to the guy for the back lot rent and accept the title to the home in lieu of payment for the judgement. Barring that:
I’ve personally tried quite a few different tricks. Offering them money to leave has been my most effective.
Any information I’ve ever wanted off a title, (VIN number, year, make, title holder, address, taxes owed, pretty much anything…) I have just called the auditor and asked. They have never asked who I was, they just gave me the info I needed. I don’t know if the person at my local auditors office is just a moron, or if this stuff is public record. I’ve never asked, and I’ve never been denied any info. also, I’m in Ohio, so there may be different rules here than where you are…
If the guy is stubborn and won’t work with you, you just might have to go the eviction route, which I assume will take some time, so you should at least get it started now. You can always cancel later if you come up with a different plan of attack.
