Thanks for the great article…although I have to point out many of the items listed are not passive but active, such as selling bodily fluids, writing blogs or resumes, and collecting bottles and cans. To be truly passive, the income source must require no effort on your part (after initial setup). Real estate, dividends, P2P lending…these are truly passive income sources.
The biggest surprise is real estate being second to last on my Passive Income Ranking List because I’ve written that real estate is my favorite investment class to build wealth. Physical real estate doesn’t stack up well against the other passive income sources due to the lack of liquidity and constant maintenance of tenants and property. The returns can be huge due to rising rental income AND principal over time, much like dividend investing. If you are a “proactive passive income earner” like myself, then real estate is great.

Crowdfunding is a newer way to invest, having emerged onto the scene just within the last few years. Most people have heard of sites like Kickstarter and GoFundMe, and a very similar concept exists for real estate. Developers are always looking to raise capital to fund their projects. Through the various online platforms, investors have access to these projects and can choose to invest in both residential and commercial properties. See the List of My Favorite Crowdfunding Sites.
The age old argument of total return versus income has been, incorrectly imo, categorized as an either or proposition. We are going to do both. Right now I have a lot cash in an on line money market. I also have investments in 2 passive Index funds in a taxable account. We then have substantial 401ks/IRA’s which we won’t touch for at least 10 years. My wife will continue to max out her sep and we will continue to invest in the index funds although with a smaller amount. We have already factored that in. I looked at how to cut into the monthly deficit. Here is what I observed.
In addition to opening a brokerage account, you can also invest in peer-to-peer lending firms like Lending Club. I’ve been using Lending Club for a few years, and my net annualized return was 6.02% percent last year. Picking the right investments is easy since the platform offers automatic investing, but you can also pick your own notes if you're brave and want to learn the best ways to leverage the Lending Club platform.
