Retirees are paying a high price as the world stimulates its way out of the GFC (Great Recession).  After a 30-year bull market to the lowest interest rates the world has ever seen, bonds have become highly priced and now don’t generate enough to meet income needs.  Just 5 years ago the average income from $100,000 invested in a 10 year Australian Government Bond (10yrs) was $5,600 p.a.  – now it’s less than half at $2,600 p.a.

I've now only got an SF rental condo and a Lake Tahoe vacation rental in my real-estate-rental portfolio. Although I miss my old house, I certainly don't miss paying $23,000 a year in property taxes and another mortgage, and dealing with leaks and managing terrible tenants. I drove by the other day and couldn't believe how much noisier and busier the street was than where I currently live. I wouldn't be comfortable raising my son there.

You can find dividend stocks using Google Finance Stock Screener which is free to use. Set the search criteria for the P/E Ratio, and Dividend yield (shown as a percentage) criteria. You can set minimum and maximum values; in the dividend yield box, set it between 2 and 100. This will search for stocks that pay dividends worth between 2-100% of the current stock price.
As a millennial in my mid-20’s, i’m only just starting out on my journey (to what hopefully will be at least 5 streams of income one day) and i’m trying to save all that I can to then make my money work harder and invest. It’s difficult though because a lot of people say you should be saving for retirement and have an emergency fund (which is so true) but then on the other hand, we are told to take risks and invest our money (usually in the stock market or real estate). And as a millennial it’s so hard to do both of these things sometimes.

That is a nice list of passive income sources. Actually, the most up-to-date list of dividend growth stocks is the list of dividend champions, maintained by Dave Fish. The list of dividend aristocrats is incomplete at best. For example, the dividend champions list has over 100 companies that have managed to increase dividends each year for at least 25 years in a row. The list of dividend aristocrats has no more than 50 – 60.
What are your thoughts on an Immediate Annuity as a passive income vehicle? I suppose it’s not a great investment since you never get your principal back, but the risk is zero and the cash flow is fairly good, approaching 6% currently. And, since you are guaranteed payments for life, you may not care that you never see your principal again anyway since you’ll be dead!
These days, low-risk bond yields aren’t enough to meet most income needs. When investing in bonds, the income typically comes as coupon payments – contractually guaranteed interest payments at predictable intervals.  There are many kinds of bond income available, so you must strike a balance between reaching for higher income (yield) and limiting risk.
