One way to make quick cash is to have a garage sale. Don’t have a garage? Host it online. You can sell your stuff on eBay, Poshmark, Craigslist, the Amazon Marketplace, and plenty of other places. Some are tailored to specific types of items, so you might do a mix: Poshmark is for clothes, Amazon Marketplace is for books, Craigslist is for that bike you said you’d ride but never did, and eBay is best for old tech. Make a sweep of your house, create a list of everything you could part with, and then get to selling.
