@Bill B., You are certainly not the only person who thinks that my approach is "scummy". Most readers will. And here is a link to a trained Attorney, hired to advise Realtors on real estate law via our local Realtors Legal Hotline. She chose more specific words for the type of conduct I proposed. "Trespass, Theft and Fraud". https://www.biggerpockets.com/... In that link I show why each of her allegations were erroneous. Below, I show why I would be thankful if what I recommended happened to me or or to the estate of someone I love.
The reason I would be thankful is that both the property and ALL of each relatives rights are preserved and enhanced for years to come. In my experience the greater danger in these situations are that no one does anything. Time after time, I see properties where the owner dies, and none of the surviving heirs care enough to step up and probate the property. Thus, the property falls into dereliction, decay, and the destruction of trespassers until at last the county forecloses for nonpayment of property taxes.
My recommendation to Lonell would preserve the property along with all the rights of the heirs (and their descendants) for 21 years. If Lonell steps up and moves in, the property is thereby secured, the property is more likely to be maintained (preserving value), and if he intends to stay there, the property taxes will be paid. For Lonell to follow my advice, he's gotten a title report, he's verified whether his Great Aunt had a will, he's determined the Ohio Laws regarding Intestate Succession, and he has researched the family tree so that all heirs listed under Ohio law are correctly identified. Then he has approached each of the deceased owner's siblings asking them if they are willing to sign over the property. In doing so he has necessarily informed them that they have an inheritance. Not a bad start.
These actions only become 'scummy' if you assume facts not supplied. Lonell specified this is Ohio (last word of his post). The property is in the rust belt. Since this is not a high value area, it is more likely the property is not worth $10's of thousands to any one of the parties. But if it is, we should not assume that the senior heirs are incapacitated regarding their finances. And if one or all of the elder relatives are incapacitated we should not assume that Lonell is going to take advantage of them by accepting their interest in the property without offering a fair return. And if a senior heir was incapacitated, and Lonell did take advantage of the infirmity, the estate or the loved ones of the incapacitated heir can still make a claim of improper transfer even years later -but only because the property value is still there. Only because someone stepped up to preserve the value and to pay the taxes.
If the senior heirs don't wish to sign away their interest, but also aren't willing to probate their interest, then it still not 'scummy' to preserve the home by using it. And, if the heirs merely neglect to make a decision today, or this month, or this year, they still have the right to make their claim at any time during the next 21 years. If Lonell follows my suggestion the property is preserved for years instead of being foreclosed for property taxes. And the property will still have value instead of being left to decay. Note that most counties will not track down the heirs to pay them any excess proceeds from the tax sale. Excess proceeds 'escheat' to the county, then the heirs inheritance is gone forever. Or, if an heir does decide to probate the home, then Lonell's use of the property grants him no extra legal interest, he has merely contributed to securing it, preserving it, and to creating some income (rent) for the estate.
So you are correct to see that there are other ways to handle this. There is always another way, and there is always a better way. Seems to me, that in this instance it is important for someone to step up and do something. Despite appearing 'scummy', what I proposed, is effective, and far more beneficial to the heirs, who are not willing to probate their inheritance, than letting it go into property tax foreclosure. Best wishes.
