A company called StreetShares helps mostly veteran small business owners (also some non-veteran owned) acquire capital for their business cash flow needs by providing loans. What’s really cool is that these loans are funded by investors. For a $25 minimum investment, all U.S.-based investors can earn a flat yield of 5% on their money by investing in StreetShares Veteran Business Bonds.
That strategy seems waaaayyyy less risky than actively picking stocks of supposedly “reliable” stocks that issue dividends, which could be cut at any time due to shifting industry trends and company performance. Dividend investing feels like an overly complex old-school way of investing that doesn’t have a very strong intellectual basis compared to index investing.
Real estate is the obvious choice if you are going to make money on your money. I personally am not at the point where I can do any of this in a meaningful way BUT my parents are and they now own a couple homes outright and are collecting income from them to power their retirement income. It makes a lot more sense for anyone that has a chunk of cash sitting in the bank and are planning on slowly drawing from it because you technically still have all that money in a property (or multiple properties) and can sell them if you really need the lump sum of cash but you’ll earn great interest payments until you do that.
Don’t do vending machines as passive income. I thought it was passive but it’s way more than that. You have to work all the time. If you get a good account, you’ll be there twice a week. Want another job as a stable income? Good luck. What do you tell your boss when you have to go fix your machine because a dollar got stuck and is only open during normal business hours?
What are your thoughts on an Immediate Annuity as a passive income vehicle? I suppose it’s not a great investment since you never get your principal back, but the risk is zero and the cash flow is fairly good, approaching 6% currently. And, since you are guaranteed payments for life, you may not care that you never see your principal again anyway since you’ll be dead!

At some point in life, passive income becomes the ‘Holy Grail’ for every investor. For some, passive income strategies have an impact early on. For others, it comes mid-life – in an effort to prepare for the unexpected. Then there are those that don’t start pursuing it until retirement is in sight, and panic sets in. Unfortunately, there are so many myths surrounding passive income that individuals can take detours down the wrong rabbit holes for years. So what are some of the misconceptions about passive income that need to be busted?
The U.S. Internal Revenue Service categorizes income into three broad types, active income, passive income, and portfolio income.[1] It defines passive income as only coming from two sources: rental activity or "trade or business activities in which you do not materially participate."[2][3] Other financial and government institutions also recognize it as an income obtained as a result of capital growth or in relation to negative gearing. Passive income is usually taxable.
Rohn was a successful entrepreneur and motivational speaker who, after having founded several successful direct marketing companies, went on to hold speeches and mentor other like-minded people in business. Most famously, he trained Herbalife International founder Mark R. Hughes—and the rest of that MLM success story is history. The rest of the quote goes, “(…) But it won’t be long before I’m working full-time on my fortune. Can you imagine what my life will look like?” The takeaway here is that careers are slow to build, require massive time investments, and, in the long run don’t mean you’ll have too much to retire on—if you only rely on them. So, then, what are some sound ways of building residual income these days?
If an investor puts $500,000 into a candy store with the agreement that the owners would pay the investor a percentage of earnings, that would be considered passive income as long as the investor does not participate in the operation of the business in any meaningful way other than placing the investment. The IRS states, however, that if the investor did help manage the company with the owners, the investor's income could be seen as active since the investor provided "material participation." 
In equity valuation, residual income represents an economic earnings stream and valuation method for estimating the intrinsic value of a company's common stock. The residual income valuation model values a company as the sum of book value and the present value of expected future residual income. Residual income attempts to measure economic profit, which is the profit remaining after the deduction of opportunity costs for all sources of capital.
