If you are particularly good at somethings, say map design, capable of creating a series of video lessons, you can become a tutor at SkillShare. You’ll be in good company with folks like Seth Godin and James Franco among others. SkillShare tutorials and 30 days teaching challenge will help you create a winning video tutorial. Your earnings will depend on the popularity of your course, but even low attendance will let you earn some decent money.

Borrowing could be a key element in this method. Say you borrow $200,000 and put in $50,000 of your own to buy a property for $250,000. Then you develop the property and sell it for $400,000. The property has increased in value by 60% but your $50,000 has now grown fourfold to $200,000. You have to select the right properties in the right areas and develop them wisely.
