Very enlightening. I like that you have a number of discreet passive income streams working for you. I”m not sure about such a large CD/ bank holding though, though it looks as though its giving you a fairly healthy income. How do you feel about a rising inflation rate on your effective real cash return? I’m looking to diversify beyond my current dividend passive income. Rental income is what I expect we’ll be harvesting next. P2P lending is a little too out of my comfort zone. I had a lot of exposure to consumer credit risk models at a prior role, and it scared me the heck away from consumer lending!
Though it can take a while to build up enough cash to put a 20% down payment on an investment property (the typical lender minimum), they can snowball fairly quickly. The key here is to correctly project income and expenses in order to calculate cash flow (the free cash you can put in your pocket after all associated property expenses have been paid). However you have to be sure to include the cost of a property manager in your calculations unless you want to manage the property yourself. Even with a property manager, you may be required to make large repair decisions every now and then – so while this is not a 100% passive activity, you are not directly trading your time for money like traditional employment.
Even if you don’t have the skills right now, it’s possible to develop them. Envato Tuts+ has a load of great courses that teach you how to make WordPress themes, Photoshop actions and so on. If you invest a few months into learning the necessary skills, you might well be able to carve out a spot for yourself in the Envato Market or in our new curated website Envato Elements. 
A freelancing service is something that can, with the right strategy and action, turn into something more productized and passive. Brian Casel, featured guest on SPI Podcast Session #158, talks about how he was able to turn his stress-inducing one-on-one design service business into something that was actually more productized, passive, and profitable. I highly recommend you listen to that episode if you have a service-based business and you feel stuck.
Creating passive income is the key to retiring, especially retiring early. If you want to retire early with the stock market you will have to save a huge amount of money, because that money has to last so long and retirement calculators depend on you using your investment to fund your life. With passive income you will have income coming in as long as you own the investment, without every eating away at the principle invested. Creating passive income may take more work than investing in the stock market, but I think it is well worth the extra effort!
