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.
Online business owners can have several streams of online income working hard for them. Multiple streams are likely to bring in more revenue and will increase opportunities for residual income. A successful online business is an online business that works for the online business owner through multiple steady flowing streams of income, and what is more important, substantial residual income.
If you have decent writing skills you can start a retainer writer business. Mastering your pitch will put you in a position where you can land awesome writing gigs. You can then complete the work yourself as you establish yourself in this space, and from there, the sky is the limit. Outsourcing is key to creating a passive income stream from this idea.

If you have a brilliant idea that appeals to a specific audience, you could create something like an educational blog or a YouTube tutorial series to generate online traffic. If your content is engaging and it sees enough daily traffic, you could sell ad space on your blog or ad spots on your channel. After you put in the heavy lifting, you can sit back, relax, and enjoy streams of passive income.
The authors found that those born to parents in the bottom 20 percent of earners (measured by permanent income, or the average labor market earnings over people’s working lives) had a 39 percent chance of remaining in the bottom 20 percent. Those born in the bottom 20 percent of the wealth distribution had a 27 percent chance of staying there. On the other end of the spectrum, those born in the top 20 percent of permanent income and wealth distributions had a 41 and 47 percent chance of staying there, respectively. (Figures showing these transitions are available in The Regional Economist article “Which Persists More from Generation to Generation—Income or Wealth?”)
There was a time when CDs would produce a respectable 4%+ yield. Nowadays, you’ll be lucky to find a 5-7 year CD that provides anything above 2.5% The great thing about CDs is that there are no income or net worth minimums to invest, unlike many alternative investments, which require investors to be accredited. Anybody can go to their local bank and open up a CD of their desired duration. Furthermore, a CD is FDIC insured for up to $250,000 per individual, and $500,000 per joint account.
No one should turn down wind farming’s ultimate passive income for the next 30 or more years … even 60 years when there is a positive cash flow on the sum total of all base payments when computing inflation for the next 60 years based on the previous 60 years, as long as the next era’s energy resource is not perfected (at which time they would not renew the option for the second 30 years).
If you’ve ever thought to yourself, “I wish there was a product that did this,” then invent it! Create a product, medical or otherwise, and sell it as a company or get royalties for it. It’s not impossible to figure out, I have many friends who have taken a concept to market. Don’t overlook an invention as a fantastic means of attaining passive income.

It is very important to understand that contacting a “professional” to learn how to do this only results in them trying to sell me crap properties (whether high end or low end). I’ve tried contacting realtors out of state, and they attempt to sell me crap or someone else’s problem. No one has a vested interest in actually helping someone or teaching them about how to get an out of state rental. very frustrating. I could go out tomorrow and buy a rental in my city, but that is the last place I want to own one. Anyone? Are there an real people on here?
A different definition of residual income is that this is income derived from passive investments, rather than from a person's active income-generating activities. Examples are interest income, royalty income, rent, and increases in the value of investments held. Individuals typically work throughout their careers in order to build up a sufficient amount of this income to support them during their retirement.
