The first follows the startup path we outlined above: You have a disruptive idea for an app or piece of software, you validate the idea with real customers, and then raise money to hire developers or a development studio to build, launch, and scale your software. If you’ve done everything right, your software will be accepted to the Apple and Google Stores and you’ll make money every time someone downloads it or pays for a premium feature.
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.

A more old-fashioned way to make money renting property is to buy one or more homes to rent out to tenants -- typically for a year at a time. This seems easier -- and more lucrative -- than it often is, as landlords have to pay for maintenance, repairs, property taxes, and insurance, and their cash flow is halted during periods when their property is un-rented. In addition, dealing with tenants can sometimes be troublesome.
With drop shipping, you’re effectively partnering with a manufacturer or wholesaler to sell their products. This way, you don’t pay upfront costs to buy inventory, aren’t sitting on unsold items taking up expensive warehouse space, and don’t have to deal with shipping the products yourself. You simply create your site, fill it with drop shippable products, and drive in customers, with almost everything else done for you.
The best part about starting a blog is that it can lead to a sizeable income. It takes a lot of work and dedication, but it’s possible.

Amazon makes it fairly easy to list and sell old books, games and devices on its marketplace. You can make more than just a few bucks If you have pricey textbooks from college. Be sure the books are in good condition. You'll get negative reviews if you attempt to sell books that are falling apart or games that are scratched up. Remember, be upfront about any defects, no matter how small they might be and no matter how few people might readily notice it.
