Another way to make money if you only have a few days is to sell items on eBay. You can typically set items to sell in just a few days, and you can have the money in your PayPal account instantly. If you are going to sell on eBay, you have to have excellent pictures. To achieve this, make sure to take photos of your items in a place where they have enough light. Make sure pictures aren’t blurry, and write as much detail as possible in the item description in clear, easy to understand English.
If you're running on fumes, financially speaking, but you have some money coming your way soon, consider pawning something of value to borrow fast cash. Of course, to get those items back you'll need to pay back the loan with interest. If you don't pay it back in time, that you'll lose the item. If it's really something that has a lot of intrinsic value to you, don't do it. But if it's something that doesn't, you can certainly consider it depending on your situation.
Another seemingly free site you can make money from is Wikipedia. People who say it’s easy to edit Wikipedia have clearly never tried editing Wikipedia – it’s a pain. Thankfully it’s a pain for companies as well, so many of them are willing to pay editors to assist them in the editing process. You’ll become a bounty hunter in a way, choosing your own lines to cross and keep. If editing is something you like to do, and you’re willing to put in the work it takes to learn Wikipedia’s dispute process, roll up your sleeves and try this one out.
The two popular ones are Poshmark and TheRealReal. Both make it dead simple to sell (and buy!) luxury items. The RealReal will pay you 60% of the sale price (more if you sell a lot) and Poshmark has a tiered commission structure. Sale prices under $15 pay a $2.95 flat fee and everything else is just 20%. Tradesy is another company and they take just 9%.
Try flipping houses if you have experience with making home repairs. As you may know from watching popular home improvement shows, flipping homes involves buying up a lower valued property that needs work, and then fixing it up for resell. To get started, you’ll need to have financing either through a bank a partner. Then, you can buy a property that’s priced below market value. After you renovate the property, you may be able to sell it for a profit.
