One of the best ways to build wealth is to get a handle on your finances by signing up with Personal Capital. They are a free online platform which aggregates all your financial accounts on their Dashboard so you can see where you can optimize. Before Personal Capital, I had to log into eight different systems to track 28 different accounts (brokerage, multiple banks, 401K, etc) to track my finances. Now, I can just log into Personal Capital to see how my stock accounts are doing, how my net worth is progressing, and where my spending is going. 

In real estate, your passive opportunities are in private lending and rental properties. Private lending commonly involves lending funds to a real estate investor or business in exchange for a set return and length of time. (Full disclosure: I am co-partner of a turnkey investment company.) Turnkey rental properties allow the investor to be as hands-off as they like. This means a turnkey company purchases, rehabs, tenants and manages the property. To truly make this a passive investment, turnkey companies do all the work for you.
​Network marketing, or multi-level marketing, seems to be on the rise. Companies such as Young Living Oils, Avon, Pampered Chef, and AdvoCare are all multi-level marketing companies. You can earn passive income through network marketing by building a team underneath you (often referred to as a down line.) Once you have a large team you can earn commissions off of their sales without having to do much.
This is the best post I’ve seen on passive income streams. I’m similar to you in that I worked in IBanking for a few years but wanted out. My approach is a little different, instead of starting with the CD’s, I’m trying to build up my net worth with riskier asset classes such as stocks and real estate to get the benefit of compounding. Then, as I approach my retirement year goal, I’ll start moving them into CD and bond ladders. In theory at least, it’s best to have the highest net worth just before retirement, then convert them to risk free passive income. You’re method is more patient and probably more practical than mine. I guess I’m willing to take more risks.
Everything passive first takes active energy. The time to put in the effort is when we are young and not ravaged by disease or burdened by family obligations. I remember being able to snowboard from 9am until 4pm every day for a year. Now, I’m lucky to last from 11am until 2pm without wanting to go to the hot tub and drink a bucket full of beer! If we can appreciate how lucky we are when we are young, we’ll be able to maximize our vitality and live financially freer when we are older.
Given the growth in the sharing economy, your junk can start to pay for itself. For example, if you have some awesome vintage furniture inherited from your grandmother sitting in a storage unit, you can rent this out to photographers for their “styled shoots” which are becoming all the rage. If your furniture is more modern but you still can’t bear to get rid of it – perhaps a home stager will be interested.
* I use Personal Capital to track all my finances in one place. It’s much easier to use their free software to follow 28 accounts on one platform than to log into various accounts to check my balances. They’ve also got great tools for x-raying your portfolio for excessive fees, recommending a more optimized asset allocation, and planning for retirement with their Retirement Planner.
