Note: There are dozens of other survey sites out there. These just happen to be the more well-known ones that have a reputation for paying out in a timely manner and not having impossible standards for cashing out. As always, be careful with your personal information. I recommend using an entirely separate email address for survey sites so they don’t clutter your inbox.
Research Pricing (And Set Fair Starting Prices): Before setting prices for each item, research your local Craigslist website and (if possible) nearby yard sales to get a sense of how to price them. Remember that many buyers will try to haggle – so set prices a bit higher than your bottom dollar, but not so high that you’ll scare off first bids. 10% to 15% is a good rule of thumb. Consider bunching low-value items, such as old CDs, into lots of five or 10, or offer x-for-$y deals.
There are a variety of online lenders out there, and if your credit is fairly good, you can apply for a personal loan online and be approved almost instantly. The money will still take a few days or even a week to hit your account, and the interest rate will be higher than, say, a home equity loan. But a personal loan from a reputable company — and be careful, for some online lenders are little more than payday loan shops online — beats credit card debt for a couple of reasons: Installment loans are better for your credit than revolving credit card balances, and even a 10% interest rate is preferable to what you’d pay for a cash advance.
Flip real estate. "House flipping" refers to the process of buying cheap, run-down property, increasing its value (either by adding improvements or simply by waiting for the market to perk up), and then re-selling it for a profit. With smart choices and practical know-how with regards to home repair, you can stand to make thousands of dollars per flip, although unexpected expenses and a bad real estate market can leave you in the red.
Use the law of supply and demand to your advantage. Most of us are familiar with the law of supply and demand--the more there is of something, the cheaper it is; conversely, the rarer the product or service, the more expensive it is. However, other than when we get to a toy store before sunrise to get on line for the latest fad toy that kids can't get enough of, we don't really apply the law of supply and demand to our own lives--particularly our careers. For example, if you're aspiring to do something that many, many other people want to do (so much so that they do it for free, as a hobby) then it will be far more challenging for you to make money doing it. On the other hand, if you do something that most people don't want to do, or if you get very good at doing something most people don't do all that well, then you can make a whole lot more money. In other words, choose a career in pharmacy over photography.
Shipping. You will only have a few days to ship a book after it sells, and even less time if you agree to include two-day or overnight shipping as part of your options. And since you’ll want to save as much as you can on the shipping, you’ll have to devise a plan. Many people set aside specific days for shipping – say 3 days a week – and then make one big trip to the post office. As long as there isn’t anything else in the package, you can send books via media mail, which is the least expensive option. Finally, your books will need to be packaged in a way that they won’t get damaged in transit.
