Real-estate crowdfunding ($9,600 a year): Once I sold my SF rental, it was natural to reinvest some of the proceeds into real-estate crowdfunding to keep sector exposure. I didn't invest a lot in some of my favorite real-estate investment trusts because I felt a rising interest-rate environment would be a stronger headwind for REITs. But if I could be more surgical with my real-estate investments by identifying specific investments in stronger employment-growth markets, I thought I could do better.
​Udemy is an online platform that lets its user take video courses on a wide array of subjects. Instead of being a consumer on Udemy you can instead be a producer, create your own video course, and allow users to purchase it. This is a fantastic option if you are highly knowledgeable in a specific subject matter. This can also be a great way to turn traditional tutoring into a passive income stream!

In the residual income model, the intrinsic value of a share of common stock is the sum of book value per share and the present value of expected future pershare residual income. In the residual income model, the equivalent mathematical expressions for intrinsic value of a common stock are V0=B0+∑t=1∞RIt(1+r)t=B0+∑t=1∞Et−rBt−1(1+r)t=B0+∑t=1∞(ROEt−r)Bt−1(1+r)t 

When most people think of investing opportunities, they think of stocks, bonds, and precious metals. While these are still some of the most common ways to invest, the platforms have evolved, and there are more options than ever. Gone are the days of mountains of paperwork, high brokerage fees and unattainable account minimums. Now you can invest on your own terms.
There are two primary types of public REITs: traded and non-traded. Publicly-traded REITs offer the benefits of liquidity, because it is traded openly on a stock exchange. However, this liquidity is likely to be priced into the value of the shares, resulting in a “liquidity premium”, or a cost that all investors pay for the ability to buy and sell the asset whenever they wish. The liquidity premium results in lower relative returns for all investors, regardless of whether or not they choose to sell their shares. Furthermore, publicly-traded REITs tend to be correlated to broader market volatility, meaning that the share value may fluctuate depending on how the stock market is doing, regardless of whether or not anything has changed with the underlying properties owned by the REIT.
If you have a spare bedroom, you can find a roommate or list the space on AirBnB for travelers. Having a roommate is the more passive of the two, as being an Airbnb host will require more work in the form of turning over the room between stays. This is a super painless way to earn $500 to $1,000 a month without much effort – you may even be able to cover your mortgage payment with this extra income!
Residual income has two real definitions. Let’s look at those first. Residual Income is income that continues to be generated after the initial effort has been expended. Compare this to what most people focus on earning: linear income, which is “one-shot” compensation or payment in the form of a fee, wage, commission or salary. The other definition for residual income is not actually a type of income, but rather a calculation that determines how much discretionary money an individual has available to spend after most monthly bills are paid. We believe that income that exceeds your expenses is called PROFIT! So, we are going to use the first definition for the sake of this document.
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.
