But, is it worth it? Absolutely it is. Niche blogs can command vast audiences, and thus opening the opportunity to several passive income streams as you might see fit. Should you decide to sell anything to that audience, you can market a wide array of products, services and information to them. But be wary of what you promote so as not to lose their trust.
Amazing article Jim. Jammed packed with great information and inspiration for a finance blogger looking to find ways to diversify income streams. Building up your capital, achieved through saving more than you earn as you described, will open doors to a lot of activities in the future. The name of the game is putting your savings to work to turn expenses and idle cash into income producing assets. It isn’t easy when you are starting from $0, but through discipline and time you will eventually be able to achieve your goals and begin using the methods you described to diversify your income streams.
One absolute valuation method which may not be so familiar to most, but is widely used by analysts is the residual income method. In this article, we will introduce you to the underlying basics behind the residual income model and how it can be used to place an absolute value on a firm. (The DDM is one of the most foundational of financial theories, but it's only as good as its assumptions. Check out Digging Into The Dividend Discount Model.)

Additional income not only provides peace of mind, but it also means you need less money to retire on.  If your side business provides you $3000 a month, and you need $7000 a month to live on in retirement, you may be able to retire 5 or 10 years earlier than you otherwise might.  Instead of a $2.1 Million portfolio, you may only need $1.2 Million.  This, of course, assumes you’re willing to keep running the side business.
For those of you who don’t want to come up with a $220,000 downpayment and a $900,000 mortgage to buy the median home in SF or NYC, who don’t want to deal with tenants or remodeling, and who wants to not do any work after the investment is made, check out Fundrise. They are my favorite real estate crowdsourcing company founded in 2012 and based in Washington DC. They are pioneers in the eREIT product offering and they’re raising an Opportunity Fund to take advantage of new tax favorable laws.
Building a smartphone or tablet app requires a fair amount of technical expertise, but it can pay off handsomely if successful. It doesn't have to be particularly complex or chock-full of features either; a simple one that solves a problem or is entertaining enough to attract users works fine. You never know what may suddenly become popular. For example, the minimalist game Flappy Bird was such a craze that at one point its developer was earning $50,000 dollars a day through in-app advertising. Of course, expecting a success like that is foolhardy, but one can always hope.
With that being said it's pretty hard to get traffic quickly, but if you've heard of Amazon FBA you can sell products on there website and basically steal their traffic for your own benefit. This is my main source of income, its online and for the amount of effort I put in, it's pretty easy. (nothing is get rich quick, it does require work) but in terms of every way to make money online, this is probably the fastest and easiest to generate full time income in my opinion.
My returns are based on full cash purchase of the properties, as it is hard to compare the attractiveness of properties at different price ranges when only calculating down payment or properties that need very little rehab/updates. I did think about the scores assigned to each factor, but I believe tax deductions are a SIGNIFICANT factor when comparing passive income steams.

Recognition of an identifiable intangible asset in the group accounts that was not previously recorded in the investee company balance sheet creates a distortion in valuation under a residual income model. The amortization of such intangible assets reduces the combined ROE, and hence results in lower valuation of the combined entity compared to the sum of the values of individual entities prior to acquisition. To remove this distortion, the amortization of intangibles capitalized doing acquisition should be removed prior to computing the ROE used for residual income valuation.

"Multiple Streams of Income" by Robert G. Allen is a book is full of great information on how to free yourself from "the rat race." Although some of the information is outdated for our current economic climate, the information is still valuable, and heartily recommend the read. There are many chapters of relevant information to balance anything you may consider unusable. He teaches you that there are many ways to earn money outside of a regular job. He also leads you through determining which avenue is right for you, and gives you all the tools you need to get started on the basics. "Multiple Streams of Income" has helped me alot.
"But for our jobs, for how we make money, I think many of us — most of us — have one way we make money. It can be very risky. I've really come to believe, and have done a lot of research over the years, that one of the best ways that we can create real, legitimate professional stability for ourselves is by choosing to cultivate multiple income streams.
First: I understand why you would say that such investments are restricted to only accredited investors, because generally, that’s true. There are means, under federal securities regulations and Blue Sky laws in each state, to sell interests to non-accredited investors – but usually those means are so heavily regulated and involve disclosures so similar to cumbersome registration requirements that it is not worth it for the seller to offer to non-accredited investors.
We pitched to an angel investor group. They were very excited about the idea but wanted to know who amongst us (doctor, accountant, salesman) was doing the coding. When they heard we were outsourcing it, the wind went out of their sails immediately. They did want to meet with us again once we brought a coder on board but that person proved elusive to find. Coders in our area are looking for the steady paycheck, not willing to gamble on a startup.

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.

If you’ve got a book you’re itching to write, you can still go with the traditional publishing route. (We published our first book using a traditional publisher.) Whether your book is fiction or non-fiction, a publisher can help get your book into print and onto shelves in both online and traditional book stores. This is still a good route, although it may take more work and be more expensive than some other options.
Successful YouTubers choose a theme for their channel—ranging from humorous commentary to gardening. As you acquire subscribers to your channel, your number of views becomes more consistent, which in turn grows your residual income. While you’ll need to produce regular videos to maintain your following, a couple hours of filming and editing pales in comparison to the revenue you can generate with minimum effort.
I’m a 45 year old business owner who also has focussed on diversifying my income streams. I have a short term vacation rental in Florida that I bought for $390k in 2012 and net rental income for the last three years has been growing steadily. 2015 I am at $70k gross right now but should end up at $80-85k with net around $45k plus we use the place about 35 nights a year.

One of the easiest ways to increase your passive income is to shift your savings to a bank that pays a higher yield on your savings — for example, Discover Bank and EverBank pay almost 1% for your money. Although it doesn’t sound like much (especially in this low interest environment), little things do add up and eventually interest rates will rise.

Well, the number seven may not be magical, but it does seem these concepts are two sides of the same coin. Yes, the streams may eventually make the millionaire, but it’s also true that the millionaire understands the importance of multiple income streams–without them, after all, he or she may never have broken the million dollar mark. So, he or she continues to increase their streams of income.

If you lease a car for three years, its residual value is how much it is worth after three years. The residual value is determined by the bank that issues the lease, and it is based on past models and future predictions. Along with interest rate and tax, the residual value is an important factor in determining the car's monthly lease payments. In capital budgeting projects, residual values reflect how much you can sell the asset for after the firm has finished using it or once the asset-generated cash flows can no longer be accurately forecast.
Residual income is the amount of net income generated in excess of the minimum rate of return. Residual income concepts have been used in a number of contexts, including as a measurement of internal corporate performance whereby a company's management team evaluates the return generated relative to the company's minimum required return. Alternatively, in personal finance, residual income is the level of income that an individual has after the deduction of all personal debts and expenses have been paid.
