Passive Income: This is the work you do for ends that will provide you with resources for the long-term. Even after you stop contributing to the effort, you are compensated again and again. Passive income is building your own empire to gain the kind of freedom we all dream about. Unlike active, it needs a bit more dedication and hard work up front, but all of which pays off in the end.
And real estate does more than just track inflation – it throws off income (which is important to some people and useful to most). And while your underlying asset is appreciating, the income also grows as rents increase over time. And if you make smart and well-timed purchases, both rents and asset values can increase at well above the rate of inflation.
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.
