​Affiliate marketing is the practice of partnering with a company (becoming their affiliate) to receive a commission on a product. This method of generating income works the best for those with blogs and websites. Even then, it takes a long time to build up before it becomes passive. If you want to get started with affiliate marketing check out this great list of affiliate marketing programs.
I prefer assets that make me a high return for the lowest amount of work possible (semi-passive involvement). And assets that pay me in several unique ways. Cash flow is only one way RE makes money for me. I also get principal reductions, appreciation, tax advantages (depreciation), and I control the rental increases on a yearly basis. Plus a majority of the capital is provided by the secondary market on 30 year fixed low interest rate debt.

However, the RI-based approach is most appropriate when a firm is not paying dividends or exhibits an unpredictable dividend pattern, and / or when it has negative free cash flow many years out, but is expected to generate positive cash flow at some point in the future. Further, value is recognized earlier under the RI approach, since a large part of the stock's intrinsic value is recognized immediately – current book value per share – and residual income valuations are thus less sensitive to terminal value.[5]

The second form of residual income, passive income, is often a vital part of wealth creation. There are only so many hours in each day, and when a person trades hours for dollars, there is a maximum amount of income that person can earn. For instance, if a person earns a specific amount each hour, there is a limit to how many hours are available to work. Once they reach that maximum amount of time, they cannot earn more money.
In mid-2017, I sold my San Francisco rental property for 30X annual gross rent and reinvested $500,000 of the proceeds in real estate crowdfunding. I’m leveraging technology to invest in lower valuation properties with higher net rental yields in the heartland of America. With the new tax policy starting in 2018 capping state income and property tax deductions to $10,000 and limiting interest deduction on mortgages of only $750,000 from $1,000,000, expensive coastal city real estate markets should soften at the expense of non-coastal city real estate.

The net operating income is the amount of money that has been made once all of the person’s expenses have been subtracted from it. For instance, in order for an author to determine his net operating income, he would have to deduct the costs involved in creating the book from the amount that he earned. Designing the book cover, editing the book, and publishing the book are all examples of these kinds of expenses.
For those who prefer a more do-it-yourself style but still want their investments to be managed automatically, a robo-advisor like Betterment may be better suited. After completing an initial questionnaire, this program will automatically invest your money based on things like your risk tolerance and time horizon. They’ll even rebalance your portfolio when necessary – all automatically, of course!
If retirement is a goal of yours (and who doesn’t want to retire someday?!?), it’s important to learn how to start investing. In fact, funding your retirement accounts should be at the top of your list. While these accounts won’t help your immediate situation, by stashing cash now, the residual income they create should help propel you through your golden years.
The first form of residual income, the leftover cash after bills and expenses are paid, is important when a person is growing their savings account or is seeking a loan or financing. When getting a loan, there must be an adequate amount of residual income available to ensure a person has the money to make the loan payments each month. If there is not adequate residual income, financing or loans will not likely be approved.
One aspect you might want to add to your scoring is “inflation protection”. At one end, bonds and CDs generally pay a fixed nominal coupon that doesn’t rise with inflation. Stock dividends and Real estate rents (and underlying property value) tend to. Not reallly sure how P2P lending ranks- though I suppose the timeframes are fairly short (1 year or less?) and therefore the interest you receive takes into account the current risk free rate + a premium for your risk. Now that I think about it, P2P lending probably deserves a lower score in the activity column than bonds too (since you probably need to make new loans more often).
There is a specific tax definition of passive income, known as “passive activity” to the Internal Revenue Service. Passive income is any income you make without actively working or are materially involved. The IRS defines it as any rental activity or any business in which the taxpayer does not “materially participate.” Nonpassive activities, or active activities, are businesses in which the taxpayer works on a regular, continuous, and substantial basis.
Loans for service members currently on active duty entail similar residual income standards, but these are typically lower by some 5%. Furthermore, if you have any dependents (children, parents, spouses), who are financially self-reliant and can make proof of their sources of net income they earn (like jobs or other ways of making a living), which could offset their own debt, you can write them off your RI standard list.
1. The batting cage idea is very risky. I’ve seen many of them close over the years and it is not anything close to passive income if you want to keep the business going. You have to continually promote it and target youth leagues, coaches, schools etc to catch all of the new players who grow up and want to play. I’ve played at probably 8 batting cages over the years and 7 of them closed.

Another way to generate passive income is to invest and be a silent partner in a business. This is very risky, but with risk comes the potential for high returns. For example, several years ago both Lyft and Uber were looking for private investors to invest in their companies. Today, they are worth billions - but you as an investor would only reap that benefit if they go public via an IPO, or get acquired. So, it's risky.

Looking for ways to build financial wealth long-term without adding more work to your daily life? Residual income allows you to increase your fortune passively — meaning you’re earning cash while you eat, sleep, and brush your teeth. With the substantial increase of online platforms and opportunities, residual income is easier to achieve than ever before.
To save time and effort, a person can group two or more of their passive activities into one larger activity, provided they form an "appropriate economic unit." When a taxpayer does this, instead of having to provide material participation in multiple activities, they only have to provide it for the activity as a whole. In addition, if a person includes multiple activities into one group and has to dispose of one of those activities, they’ve only done away with part of a larger activity as opposed to all of a smaller one. 

However, residual income typically has an expiration date, especially if it is being earned through a business. Effort must be continuously put into the business in order for someone to continue to receive residual income. Businesses must continue to market themselves in order to remain relevant. The best way to look at residual income in this sense is that it is a part-time job that earns full-time income.
Domain names cannot be replicated. If one is taken, the only recourse would be to approach the owner to discuss a sale. While there are other variations you could choose, sometimes owning a certain domain (especially if it is attached to your business) can be worth the premium. Often, people will scout out domain names that are still available, buy them, and then sit on them in order to sell them down the road. Depending on who may want the domain down the road, you could sell it for a large markup.
I’m feeling inspired! I’ve been a PT for 19 years and I feel I have so much experience to offer but have been so intimated by starting a blog. I also subscribed to Michelle’s website but wasn’t sure it was for real. Is it for real? After reading this I feel like it’s time to take the plunge, I need to start a blog, I have so many ideas and even course ideas. I want to get away from the paperwork that plagues our healthcare system but not leave the field so the blog just might be the answer. I’ve been a landlord for 15 years now, great investment for sure, renters paid for the down payment of our house and should hopefully help pay for our kids college. I’d love to have one more! Thank you for the inspiration, wish me luck with my blogging!
