But, you don't need to go further than that. You can simply write it and publish it and collect the income. That's all. Send out a couple emails to your list (if you have one) or post it on social media, and there you have it. Passive income. Now, the amount of income you receive depends on the quality of the book you've written. How well did you craft the message? How targeted was the information to your audience? It counts.
Venture Debt ($12,240/year): The first venture debt fund has returned almost all my initial capital so I decided to invest $200,000 in the second fund. I took a risk investing $150,000 in my friend’s first fund, so I’m hoping there’s less risk in the second fund given he has four more years of experience on top of his 12+ years experience running a venture debt portfolio for another company.

Generating multiple streams of income can have a major impact on your finances. Even an extra income of $500 each month could go a long way towards paying down debt or increasing your investments. We often hear about the importance of diversifying our investments, but diversifying our income streams is just as important, particularly in difficult economic times.
The basic idea behind this approach is that a rate of return is required by investors from their resources which are under the management of the firm, provide compensation for their opportunity cost and account for the level of risk. This rate of return is considered the cost of equity and a formal equity cost has to be subtracted from net income. Again, for creating shareholder value, management should be capable of generating returns which is at least equal to this cost. Therefore, even if the income statement of a company report a profit, it can be actually unprofitable economically. Thus, it is possible that a value may be negative in this case, even though it is positive when traditional discounted cash flow approach is applied.
Building an app today is likened to creating a website back in the day. Nearly everyone is building an app. Everyone. For that reason, there are droves of developers that could help you create the right app. But be prepared to invest time and energy into this project, not only on the conceptualization and development of it, but also on the marketing side.
Investing in rental properties: Another form of real estate investment, rental investments (i.e. becoming a landlord) could steer you down the passive income path of steady monthly rent checks that you can use to pay off a mortgage loan on the rental property. After the mortgage is paid off, those monthly checks go right into your bank account -- potentially for years to come. 
Passive income is the holy grail of income generation, allowing you to earn money on autopilot, without sacrificing any additional time to produce those funds. And, time, as we all know, is life’s greatest equalizer. No human being on earth, no matter their race, gender, creed, color of their skin, religious beliefs, net worth, occupation or geographic location, has more time than the next human being. We all have the same amount of time in a day. 24 hours. That’s it.
Lending Club went public in 2014 and is now worth about $1.7B. They advertise P2P lending returns of over 7% for well-diversified portfolios of over 100 notes. I’ve personally been able to achieve a 7.4% annual return over the past two years in a completely passive way by investing in A and AA notes. Others have achieved a 10% annual return through relatively minimum effort.

Money from dividends, for example, are taxed at a lower rate than money from a job. A business owner who works in the company she or he founded would have to pay more self-employment payroll taxes compared to someone who merely had a passive interest in the same limited liability company who would pay only income taxes. In other words, the same income earned actively would be taxed at a higher rate than if it were earned passively.

The type of business you should start depends on your passion and existing skill set. If you love baking, for example, you could consider starting a home-based cake or brownie business. Love to sew? Spend your free time creating the perfect crafts, then turn around and sell them with your own Etsy store. Love dogs? Consider watching dogs out of your own home and marketing your services on a website like Rover.com.

Freelance writer: If you have a knack for writing, you can earn great money writing for others. Not sure how to start? Contact bloggers, who are always looking for great writing. As blogs grow, they can afford to pay freelancers good money for quality articles. Websites looking to build links also hire freelancers to write guest posts to be published on blogs and websites.

While residual income can be used to describe the amount of net income after all costs are paid down, it also refers to the amount of money you continue to generate after your initial work is done. There are countless ways to make money, but some are much more time-intensive than others. Active income, for example, refers to when you directly act or perform a service for money, including salaries, wages, tips, commissions, and income from a business you’re actively involved with.

Let’s say you just decided to sign up for the Chase Sapphire Preferred® card. Once you had the card in hand, you could begin using it for purchases and earning cash back for every swipe. For every dollar you spend on regular purchases, you’ll get 1 percent back in the form of rewards. For dining and travel purchases, on the other hand, you’ll score a smooth 2 percent back.

Varolo is an advertising campaign that allows major corporations (like Coca Cola, Lysol, and others) to reach their target audiences with a high return on investment. Major corporations are desperately trying to find new ways to advertise to people as the newspaper continues to decline in demand and in an age of DVR. Varolo is the newest opportunity that actually pays you, the one being advertised to, to watch their advertisements. You can join the campaign and earn a little extra spending money by viewing and rating commercials and even trailers for major motion pictures. While the trick is to devote 5 to 10 minutes of each day rating what you see, you should also be motivated to invite others along through Facebook, Twitter and other social media so that you can increase what you profit each week.
I’ve now only got a SF rental condo and a Lake Tahoe vacation rental in my real estate rental portfolio. Although I miss my old house, I certainly don’t miss paying $23,000 a year in property taxes, another mortgage, dealing with leaks and managing terrible tenants. I drove by the other day and couldn’t believe how much noisier and busier the street was than where I currently live. I wouldn’t be comfortable raising my son there.
A business thrives or fails depending on its marketing and system for generating leads. You need leads to make sales. No audience or exposure means you won’t get fresh faces checking out what your business does. Too many entrepreneurs spend all their time on the “busy work” and not enough on audience building. There are some great ways to build an audience and generate new leads:
According to Uncle Sam, you need to be "materially involved" in an enterprise to earn active income. With passive income, it's just the opposite, as the IRS deems you to be earning passive income if you're not materially involved with a profit-making enterprise. By and large, expect income to be taxable if you are engaged in a passive income enterprise. You will need to report earnings to the IRS.
Speaking from our own experience, you can’t be a passive McDonald’s franchisee. Every McDonald’s potential franchisee will need to complete at least thousands of hours of training before he/she would be approved to acquire a franchise and only if he/she has the financial resources to acquire a franchise. It could take years before one would get a single store franchise. Until the franchisee eventually has acquired multiple stores and established his/her own management team, the franchisee would have to put his/her nose to the grindstone and work his/her ass off every day. I won’t call it a passive investment by any stretch of imagination.
