HOARDING
If you find that you hold onto things you no longer need or use for “sentimental” reasons, you could just be a hoarder. Not only could hoarding cause unnecessary clutter in your living space, but it could also cost you money if you decide to put some of your items in a storage unit.
Storage units can cost an average of $40 to $230 per month depending on the size, according to CostHelper, and no matter what the cost, paying for a storage unit is always a terrible idea.
You are also missing out on money you could get from selling possessions you no longer have use for. You can sell household items on Craigslist, or use sites like Poshmark, Threadflip and Tradesy to sell used clothes online.
