Investment properties: An investment property is one purchased with the sole purpose of earning revenue. It could be a commercial space you’ll lease out or a residential rental unit. Not only will this type of investment provide potential appreciation and tax benefits over the long term, but it can also provide residual income in the form of monthly rent (after expenses).
Also: be prepared to work hard. Initially, you’ll have to work persistently on your business or website and not see any returns. Once you’ve built up your business or product to a complete level, and established connections, then you can expect to start earning money from it. (Note that not all of these ideas are businesses; some of them can be done without needing to open up a business).
Ebooks are one of my favorite sources of passive income. Now, you can do this the simple way and just publish it on Amazon's KDP. Or, you can go all out and build yourself a book funnel. Book funnels are powerful, but they won't be fully passive. For example, if you do a free-plus-shipping offer for your ebook (converting it into a physical book), you'll need to create some one-time offers (i.e. extra training) and up-sells (i.e. an audiobook). But, a book funnel can be very powerful.
I no longer count traditional publishing as passive income because after you’ve spent half a dozen years pitching agents, arguing with publishers, and having your heart broken repeatedly only to make about a dollar per book, it’s not really passive income. More like overdue income. The responsibility that traditionally published authors shoulder is much too high and the cut far too little to make this even a profitable, let alone passive, income option for most writers.
You know the fantasy: write some ebook (or better yet, hire freelancers in Mumbai to research and write it for you at $.20/word!) on some niche topic, set up AdWords and Facebook campaigns targeted to the right keywords (you can hire those Mumbai guys to do your keyword research too), put up a cheap landing page (with copy written by... guess who!), press "Go!" on the PPC campaign, and voilà. . . just wait for the money to roll in while you sleep!
Free Email Courses – Wait a minute. Free? I thought we were getting paid. We are. We are! As an example, I have a free 7-days to Finding Work from Home series that people joining one of my newsletters can receive. Every day for a week they receive a new email telling them about a specific work-at-home opportunity. Sprinkled throughout that series are affiliate links to some of my favorite work-from-home resources. It took me just a couple days to put that series together and it goes out like clockwork to hundreds of new subscribers each day. And I earn a commission if a few of those people decide to click through and purchase my recommendations.
Some other parts of the book echo advice found in other bestsellers, with the section on how to create a lean startup being reminiscent of Eric Ries’ advice in Lean Startup – this by the way is one of the biggest lessons I think people new to the world of passive income need to realize…you can get started this week, with just $50, and still be on a level playing field with people who have a ton of money behind them (well, almost).
