After death, who then is responsible for “maintaining” the home? Specifically, until the home is sold, etc., who is responsible for paying for utilities, security systems, trash pick-up, home owner insurance, property taxes...or any other bill that would come due until such time as the property is sold, and from what account?
Assuming that your going probate route, probate basically divided into assets of Estate & claims / debts of estate. If all there is for assets is that house and whatever $ left in a bank accounts, it going to be pretty straightforward to determine Assets of Estate, have it entered & approved by judge. But if there’s rent, then every month Assets change as that rent is income / asset of the estate. And Assets must be updated & filed with court. Renting is going to need all sorts of reporting, taxes paid, perhaps permits done plus change in property insurance. Insurance could be scary expensive as a traditional homeowner policy cannot be written; a vacant dwelling policy can’t be done either. It’s going to be some kinda speciality property underwriting done. You kinda have to have insurance too cause if there’s an issue, heirs can come after whomever is executor for not having asset properly covered.
This is why often there’s what seems like an abandoned house is actually a property left vacant, not rented so it stays a static asset of an estate within open probate. Executor then just has to deal keeping up with debts of Estate against a set figure for Assets.
If there is no Will, the County/City might choose whomever was the Power of Attorney. That person goes to the bank and changes over the deceased accounts into one "Estate of______" account, to which checks are written. Copies of all bills and checks need to be kept for Probate accounting.
