One solution to this problem is to contact an estate sale company to auction off unwanted items.
Nevertheless, some people on fixed incomes might find that option unaffordable, since many estate sale agents charge high hourly fees and fixed fees from the sale in the thousands of dollars range.
Another potential solution is to donate unwanted possessions to charity.
More and more people are using this option.
It can even come with the benefit of a tax deduction for those elderly people who itemize their deductions.
