When I purchase an existing online business, I look for cash flow over the past year and where the money comes from. I want the sources to be more passive so that it does not take a lot of my time. Also, typically I will make an offer that is 18 – 24 months of profit so that I know that I will get my money back within the next two years. I hope that helps!

Unfortunately, I can’t answer that conclusively one way or the other. It all depends on you, what you like to do, your work ethic, personality, etc. If you are a good writer perhaps you could write a book and make money that way. Or, you could start your own website and do affiliate marketing. Just because you are young it doesn’t mean you can’t make money doing at least a few of these ideas. I wish you luck in your money making efforts!
All that being said, the residual income valuation approach is a viable and increasingly popular method of valuation and can be implemented rather easily by even novice investors. When used alongside the other popular valuation approaches, residual income valuation can give you a clearer estimate of what the true intrinsic value of a firm may be. (Don't be overwhelmed by the many valuation techniques out there - knowing a few characteristics about a company will help you pick the best one. See How To Choose The Best Stock Valuation Method.)
When I started building my architecture-related business in 2008, I made my first dollar through advertising. I’d spent a lot of time and money building the site and getting traffic. Then one day I threw an ad on the site one day, and I made $1.18. Sure, I could find that much under my couch cushions—but that’s not the point! The point is that I was able to build something online, put an ad up, and make money without having to do anything. I learned it was possible, and it motivated me to move forward.

Haha, that is too funny. I wanted to make an app back in the day called “MyShares” (You can probably tell how I cam up with the name at the time). The idea was that I would loan out books and DVD’s and then would never get them back. Then I thought, how cool would it be if I could rent those items out and that would motivate people to bring them back. Obviously, books and DVD’s are cheap, so this isn’t the money maker. The idea that would probably make the most money would be things like tools, ATVs, etc.
A linear income is when you trade your time for money. It’s also known as a work income. The paychecks that you receive are based on the amount of work you do. In this kind of income, you are required to put in hours of work every week. If you stop working, you also stop earning. Hence, linear income requires you to continue working in order to keep earning an income.
The churn rate of downlines is only exceeded by the churn rate of customers (that aren’t already participating in the MLM of course). Sure, Aunt Mary may give you an initial sale just to get you started, but eventually even she stops buying. But those few sales, plus the other expenses MLMs charge their reps, is enough to sustain the corporation. However, this system is only sustainable if the rep force continues to turnover.
The craziest part of this was I’d wake up in the morning and there would be more money in my bank account, from people who had bought my book overnight. When you think about it, an online store that sells something that’s digital is something that’s open 24 hours a day, 7 days a week, 365 days a year. Using tools, software and systems, you can automate the delivery process so you literally don’t have to do anything to serve that audience. That’s super powerful.
“There is no such thing as 100% passive income,” says Flynn. “Even with real estate you still have to manage your properties, or even with the stock market, which is potentially passive income, you still have to manage your portfolio. With online business, there is no such thing as 100% passive income — and this is coming from a guy with a blog called SmartPassiveIncome.com. The definition of passive income is ‘building these businesses of automation,’ but in order to keep them automated and keep that trust going with your audience on top of that, you do have to keep it up every once in a while — so a lot of time upfront and a little time after. But there is alway time involved.”
What could be a better option than to make money out of your hobby? If you’re a hobbyist who creates some sort of artwork such as sketches, doodles, paintings, etc., you can put these up on a portfolio website with your name as the domain name and sell them. You would need to frame the artwork, but do it only when you receive an order. You can easily build a portfolio website with Pixpa and sell your artwork right from there.

Nowadays, anyone can create and sell t-shirts online, even with minimal design skill and coding knowledge. You can create designs on t-shirt marketplaces that do it all for you, upload designs to print-on-demand vendors who dropship orders for you, or set up an online store and sell tees you print and ship yourself, which can be the most profitable option.

Now that you’ve chosen your market, find a way to start sharing your message, whether it’s a blog or podcast or Youtube channel, or whatever platform makes the most sense for your target market. Flynn says this is where you’ll start to build a fan base — and collect subscriber emails. You don’t need to get the whole world to follow you to make this work out financially. Wired cofounder Kevin Kelly wrote an article about 1,000 True Fans, which basically says that if you have 1,000 people paying you $100 a year, that’s a $100,000 a year. “You don’t need to serve everybody,”  says Flynn.

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.
