Zombie Title With Squater

[Robert Martin]

Ok Bigger Pockets, Got a Doozy of puzzle for y'all. Any help or ideas would be appreciated. So here is the situation: Guy dies (in 2010) with 2 properties under water with the mortgage companies by a fair amount. No will. Kid inherits properties and 'Abandons' them in probate, allowing for the banks to proceed with foreclosure. BUT the Banks never did! Title never changed and no deeds were ever recorded at the county clerks. (The banks, however have been paying the property taxes and HOA fees.) So the heir of the estate (who doesn't think/ isn't aware he still owns the properties and wants nothing to do with them) is presumably holding title, and while the banks have valid liens in place, they have not done anything with the properties. Meanwhile, one sits derelict and abandoned, and the other has a "tenant" that was there before the owner died. He hasn't had anyone to pay rent to for over TWO YEARS! This 'tenant' would love to give his money to someone and/or outright buy the property, but he can't figure out who to talk to. It would be a great deal if I could find a way to get the deed to the property either from the bank, at auction, or from the old owner's estate. Any thoughts?
