Establishing residual income allows you to accumulate wealth faster, have a more flexible lifestyle and maintain a diverse financial portfolio. As with any successful investment, hard work is required. With residual income, however, that work tends to be upfront. Once your revenue stream is established, the work and time involved is significantly lower than active income sources. With residual income, you’ll secure funds for your future, have a better idea of where you stand financially and enjoy peace of mind knowing you’re maintaining lucrative, long-term investments.  
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.
That strategy seems waaaayyyy less risky than actively picking stocks of supposedly “reliable” stocks that issue dividends, which could be cut at any time due to shifting industry trends and company performance. Dividend investing feels like an overly complex old-school way of investing that doesn’t have a very strong intellectual basis compared to index investing.

The paper identifies, and then resolves, a number of seeming puzzles in a newly identified set of stylized facts entailing movements in factor returns and shares and the wealth-income ratio. Standard data on savings cannot be reconciled with the increase in the wealth-income ratio: there is a wealth residual. An important component of this is associated with rents: land rents, exploitation rents, and returns on intellectual property.

If you're looking to get started in real estate, look at a crowd funding solution like RealtyMogul. It works similar to LendingClub - you commit as little as $5,000 towards a property. When the property is fully funded, you become an owner, and will receive your share of the earnings and appreciation in the property.  Check out RealtyMogul to learn more.
