For those willing to take on the task of managing a property, real estate can be a powerful semi-passive income stream due to the combination of rental and principal value appreciation. But to generate passive income from real estate, you either have to rent out a room in your house, rent out your entire house and rent elsewhere (seems counterproductive), or buy a rental property. It’s important to realize that owning your primary residence means you are neutral the real estate market. Renting means you are short the real estate market, and only after buying two or more properties are you actually long real estate.
This is an ideal strategy if you live in an area where real estate prices are too high to realistically invest in, or you don’t want the hassle and expense of traveling all over the country visiting potential properties. Plus, if you are new to single-family real estate investing, letting a place like Roofstock guide you through the process is a great way to get your feet wet.

Passive residual income is generated as a result of little or no direct involvement in the actual creation or production of the money. In essence, passive residual income is income that you may have stirred up, but it is still coming in whether you work or not. With income such as this, you are your own boss, or buying of stocks that pays dividends. You set your own hours and the hours that you do put in are not directly involved in the amount of revenue that you create.
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.
