She moved to a memory care facility and now has a much smaller room than her previous assisted living apartment. I paid for the movers etc. but am worried about what to do with the rest of her things.
Pam, are you assuming that your mother will not be returning to her home, or to AL? If so, do you want the furniture itself? Does your mother have a will or trust providing that her furniture and other household possessions will be distributed among her heirs?
If you're the sole heir, I think you could consider selling the furniture rather than storing it and paying storage costs, unless you want the furniture yourself or it has sentimental meaning, which I suspect is the case.
Are you talking about expensive antiques or custom made furniture? If not then I agree with Garden Artist. Paying for a storage facility often costs more than old furniture is worth. Sounds like your mom is downsizing to more manageable surroundings and it's an opportunity to declutter. Good luck!
