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!
However, you should pick a niche and blog about that. If you're launching a money related blog, maybe it'll be about how to make money in real estate or simply how to make money online. Pick the niche and stick to it. If it's a diet and fitness related blog, maybe the niche is the Ketogenic diet, the Atkins diet or some other form of diet or fitness.
Build an investment portfolio that pays out dividends (Stocks / Bonds / Mutual Funds). Dividends are payouts that companies give to their investors as a portion of their earnings. They’re often paid out quarterly. If you’ve already got an investment portfolio, it’s time to take a good look at which stocks, bonds, or mutual funds you own. You’ll see consistent returns from the ones that pay dividends. This is a fantastic way to earn passive income. Invest once and watch the returns pile up.
Of course, you can make honst money in Internet info-products, or affiliate marketing, or other such areas where people tend to get drawn to "passive income" fantasies. But, to make real money over the sustainable long-haul, you must treat these like any other business. In other words, you must provide real value to real customers with a real need.
Because you’re publishing an eBook rather than a physical book, the costs are minimal. And you don’t have to print 1,000 copies of your book hoping someone will buy it. Instead, you can write your book, create a fancy cover for $5 using Fiverr and publish through services like Amazon Kindle Direct Publishing. Amazon will handle everything for you, then take a percentage of the revenue you generate.
* I use Personal Capital to track all my finances in one place. It’s much easier to use their free software to follow 28 accounts on one platform than to log into various accounts to check my balances.
