Roofstock – Investing in rental properties is one of those passive income ideas that can be extremely intimidating, especially when it comes to finding tenants. Roofstock lets you buy properties with as little as 20% down that already have tenants living in them. That means you start getting paid from the first day of your investment. You don’t even have to physically visit the properties!
Writing an e-book is very popular among bloggers, as many have noted that “it's just a bunch of blog posts put together!” You will not only have to make an investment of time and energy to create the e-book, but market it correctly. However, if marketed correctly (through blogging affiliates in your niche, for example), you could have residual sales that last a very long time.
Residual income is the amount of net income generated in excess of the minimum rate of return. Residual income concepts have been used in a number of contexts, including as a measurement of internal corporate performance whereby a company's management team evaluates the return generated relative to the company's minimum required return. Alternatively, in personal finance, residual income is the level of income that an individual has after the deduction of all personal debts and expenses have been paid.
