Where do I begin?
The first thing you have to do is sort all your stuff. This will take a couple of days if you’ve let the situation get worse over a longer period of time.
Make piles or gather stuff from the same category in some sort of container. This way, you’ll know just how much of everything you’ve accumulated.
Donate what you can
To do your little bit to help, you might want to donate some clothes and toys instead of selling them to Goodwill. It’s not likely that they’re going to pay you for it unless you’re giving away really high-priced items, but your donations could translate as tax deductions.
So you will benefit from it somehow.
Make a profit
Parting with stuff you don’t need is a good way to build up your debt fund. You could list your items on eBay and wait for the highest bids for them.
If you want to go the old-fashioned route, hold a garage or yard sale.
Some of the items you could find lying around your house might actually be worth more than you think, like college textbooks, old paintings, and collectors’ items.
