Like we said above, there’s nothing passive about this, but if you can create another type of asset — a system for selling products — then it is. One example is to write a book, and use Amazon Fulfillment Services to automatically print and ship it every time you sell a copy, depositing the money in your account. Another example is Tim Ferriss, who hired overseas assistants to handle everything at BrainQuicken, from the marketing to the reordering. With drop-shipping (having the manufacturer ship directly to your customer), this has become easier, but you should know that it’s still a good bit of human labor to advertise, handle customer service, etc. But, it’s a good option, and you can experiment with automation and delegation as you go along.

Earn rental income. One of the more common ways that people earn passive income is by buying and then renting out property. These can be homes, apartments, land, or even individual rooms within your home. To do so, you'll have to find a property to rent out, determine a fair rental price by looking at comparable properties in your area, and then act as a landlord for your renters. You can convert this income source into truly passive income by hiring a manager to act as a landlord for you. However, this may not be economically feasible until you have several rental properties.[1]
eBay is, of course, the biggest and most popular auction and shopping site out there. You pay a small insertion fee to list your product (starting from 10 cents) and a small portion of the selling price (10%) if your item sells. Currently, insertion fees for your first 50 listings per calendar month are free. Also, if you are planning to sell on regular basis, you may want to consider setting up an Ebay store. Among other things, this will allow you to list your products at reduced rates.
If you go this route, be prepared to put in quite a bit of work up front. All of these products need to be created, tested and perfected for sale. The good news is that your initial investment will pay off multiple times. Also, there aren’t any production costs as you aren’t making any physical products. But you will still need to devote some time to product development and subsequent marketing, meaning that your work schedule may need to be trimmed a bit.

I wouldn't think of a high yield savings account as a source of passive income but your savings should be getting something (less like Seinfeld syndication residuals and more like a commercial jingle residuals!). It won't make you rich but it's nice if your baseline, risk-free rate of return on cash is 1% or more. The best high yield savings accounts (or money market accounts) offer higher interest rate and there is absolutely no risk. CIT Bank currently leads the pack with the highest interest rate.

Hi Sam! I loved your sentence, “There’s so much information in my head that I need to write it down or else I might explode.” That’s exactly how I feel! I never thought of myself as a writer, and especially not a blogger, but recently I’ve started dabbling in it and it feels so nice to get everything out! I’m dedicated to helping others succeed with personal finances, and there are plenty of “how-to” sites, but it’s important to get people thinking and motivated to prepare, plan, and save!
Crowdfunded real estate companies like Fundrise are similar to today’s peer-to-peer lending companies. Like Lending Club and Prosper, they offer a platform that matches real estate investors with investment choices. They help people looking to invest money in real estate in a passive manner. Also, investors can avoid bargaining with sellers. No need to get involved in the transfer of ownership and management of those properties either.
Do you think it’s possible to build a blog from scratch, outsourcing the work from day one (assuming I have some cash that can cover the initial expenses until the blog generates enough income to at least break even)? In other words, do you think you could you have spent your $500 max per month for the writer, social media expert, etc to build your blog to the point it’s earning the same amount of money it does now?
The much loved model for bloggers and content creators everywhere and for a good reason…it’s pretty easy to write a 60-80 page ebook, not hard to sell say $500 worth a month through online networking, guest posting and your own SEO optimized blog, and well you get to keep a large whack of the pie after paying affiliates.  Hells yeah!  Continue reading >
