If an investor puts $500,000 into a candy store with the agreement that the owners would pay the investor a percentage of earnings, that would be considered passive income as long as the investor does not participate in the operation of the business in any meaningful way other than placing the investment. The IRS states, however, that if the investor did help manage the company with the owners, the investor's income could be seen as active since the investor provided "material participation." 
Blooom: Blooom works very differently from many of the other robo-advisors. It helps specifically with your employer-sponsored accounts (401k, 403b, 401a, and 457 accounts). Blooom will go through all the investment choices and make adjustments for you. The service also automatically rebalances the account as it grows. Blooom is very inexpensive when compared to a traditional advisor at only $10 per month no matter how large your 401k grows.

How do you know if that picture shows the house you actually own? or if it even hows the ‘current’ state of the house you own?
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.
