I am still working on my passive income, however I like multiple income streams even more. My favorite is capital gains because it is one of the lowest rates. One of the best passive income streams is a pension/Social Security. As I near retirement, I like the concept of it supporting my needs and my 401k supporting my wants. In addition, my brokerage accounts are all at capital gains rates. Don’t misunderstand, I am still working on adding more because I like multiple income streams!
Rentals, just like stocks, throw off cash. With rentals we call that cash “rent”, and with stocks we call it dividends. A significant difference however is that the S&P 500 has appreciated at ~6% per year (above inflation) for the last 100 years…..Real Estate has had almost 0 growth above inflation. So are rents higher than dividends? Maybe, maybe not. But unless you got one heck of a deal, the delta in rent over dividends will have a very tough time making up for the 6% per year difference in appreciation.
You can’t start charging right off the bat without your audience knowing anything about the value you offer (though you could still indirectly earn money from them with the right ads). “The best way to go in terms of a long-term passive income business [is] delivering value and information for free, and therefore establishing expertise, knowledge and trust with your audience,” says Flynn.

There are a lot of article sites out there that share revenue, but my favorite (and it’s where I earn most of my article writing income) is InfoBarrel, which you’re very familiar with if you’ve been following my blog for awhile.  If you’re up for a very ambitious challenge, you can read about the one I wrote for earning $2,000+ per month with article writing.  The top InfoBarrel writers currently earn at least $2,000 per month.

What I find most interesting is the fact that I had never considered options like LendingTree or realityshares for other income sources. Investing in property has been too much of bad luck for people that I know personally, so I am interesting in getting involved in a situation where I would have to be dealing with maintenance issues or tenants. There are services for you to do that, but I had not come across any that didn’t eat most if not all of the earnings. Then again, I live in the NY area. Investing in the midwest would not be reasonably possible for me, directly, but reading about realityshares is something I am going to look into further. That might be a real possibility.
Right now, I’ve got my day job, some index funds, a small income from my blog (about a penny a day so far – ha!), and some knitting patterns I designed and have for sale at various sites around the internet (not surprisingly, that doesn’t bring in much either). Eventually I’d like to write an ebook, although I have no idea what the topic would be yet. I’ll keep plugging away and hopefully it’ll become clearer in the future!

Or, there is another theory for your primary salary – generate enough to have a little excess cash flow, but do it at a place that you can work stress free and have time to dabble in other projects.  A good friend of mine has this setup – he works 10-5 and makes $50,000 a year.  This allows him to easily cover all of his expenses, but the shorter hours and flexibility in his job allows him to pursue his secondary income generating ideas!

Our most significant source of income is Mrs. RB40’s earned income, but that will change when she retires in a few years. Luckily, our expenses are at a reasonable level and we don’t need to replace her whole income to keep the same lifestyle. For 2015, our other sources of income just about covered our cost of living. The high-tech antitrust settlement gave us a shove to get over the finish line. That’s just a one off, though. I’m not too worried because there are other ways to generate some income to make up for Mrs. RB40’s paychecks. Here are some of them.
Although renting out your room or home can also be a side hustle to make extra cash, it's also a great source of passive income. However, another route to go is to get an income property just for the purpose of renting it out. This is even better if you live in a touristy area, because you can probably make even more than usual during the high tourist seasons.
Another source of income (or at least revenue) can be selling things you no longer use. When we go through our closets and drawers, I tend to find a lot I can do without. Some goes to Goodwill / Salvation army / Habitat Restore (tax deduction = income), some is resold on Amazon or eBay, some goes to the trash. I’m not sure if reselling something you paid more for should really count as income, but it’s money in the door, or less money out as is the case with donations.
There are a ton of ways to diversify your investments, some of which can send real income your way. By opening a brokerage account and investing in ETFs or mutual funds, you can earn real returns you can use to supplement your income. Of course, the flip side can also happen – as in, you can lose money. So, make sure you understand the risks before you dive in.
