If you live in an area where Uber or Lyft operate, why not become a driver? If you're looking to make some short-term cash, you can definitely rake it in by working for one of these popular car-hire apps. As long as your vehicle fits within the specifications of their program, and you have a clean license, you could do this on the side, especially if you're in a crunch for cash.
Lastly, if you have a few pieces of furniture you no longer want, you can list them on Craigslist. If it’s a desirable item, it’s very likely that someone will come pick it up the same day you list it and give you cash for it. Make sure to take pictures of your item for your ad in a bright, sunny room. Stand back far from the item and zoom in. This is better than trying to get a detail shot. You don’t need a fancy camera to sell items quickly. You just need a simple camera and a lot of sunlight to get the job done.
