Returns on real estate investing vary and you don’t want to get into the business based on an estimated return but on your own calculation of what is possible for your local market and for specific properties. I have seen pretty common averages between 8% and 12% a year for single-family residential rentals with cash flow accounting for between 0% and 6% of the return.
If an investor puts $500,000 into a candy store with the agreement that the owners would pay the investor a percentage of earnings, that would be considered passive income as long as the investor does not participate in the operation of the business in any meaningful way other than placing the investment. The IRS states, however, that if the investor did help manage the company with the owners, the investor's income could be seen as active since the investor provided "material participation." 
There is a big misconception about rentals & people thinking that it’s passive.. rental income is far from passive. Many people flock to buy rentals as a way to “retire rich” but realize shortly thereafter that it really isn’t that easy or true.. Ask me how i know. I have bought a lot of houses from tired and burnout landlords. Luckily, there are better options out there.
I watched an episode of Shark Tank once where I was introduced to Major Robert Dyer. Major Dyer was pitching a new energy drink called The Ruck Pack Energy Drink. It’s not like the world needs another energy drink, but he was able to convince both Kevin O’Leary and Robert Herjevic, two of the investors on the show, to give him $150k in exchange for 20 percent of the company.
Rentals, just like stocks, throw off cash. With rentals we call that cash “rent”, and with stocks we call it dividends. A significant difference however is that the S&P 500 has appreciated at ~6% per year (above inflation) for the last 100 years…..Real Estate has had almost 0 growth above inflation. So are rents higher than dividends? Maybe, maybe not. But unless you got one heck of a deal, the delta in rent over dividends will have a very tough time making up for the 6% per year difference in appreciation.
Question: You mention receiving $200k of passive income a year, but your chart shows half of that coming from real estate holdings, and reading between the lines it appears that you hold mortgages against those holdings. Then you conclude that $200k/yr of passive income should be enough to live comfortably anywhere in the world. So are you subtracting your real estate expenses (taxes, insurance, mortgage payments, maintenance, remote property management company fees, etc.) when you report your passive income from those properties? Really I think it’s the net (after taxes and everything) that tells us what is left over to “spend” on living, right? When I set up my spreadsheet to retire early at age 47, I calculated the after-tax income I would need to live. Then I compared that to my income streams (estimating tax on the taxable income streams) to measure the surplus/shortfall. Also some good advice from GoCurryCracker: If you can minimize your taxes so you’re in the 15% tax bracket, you can possibly receive tax-free long term capital gains. I agree with your philosophy that time is more important than money as we age. I am not sure I agree with a philosophy that is fixated on needing such a large income, and would rather minimize taxes if it’s all the same on the happiness meter. Furthermore, having 20 plus income sources in the name of diversification adds stress and requires more management (TIME!). I think this is fine for those of us while young, as we have the energy to work hard. But as time becomes more important, the extra headache of managing, planning, and buying/selling our assets becomes a resented hindrance on par with the resentment we felt when working for an employer and fighting traffic each day to go to a job we hated. Every thing we own in actuality owns us, by virtue of its demands on our time and affections, and that includes investments. It also includes our home, and is a good reason for downsizing. As long as we have food on our table, a roof over our heads, and clothes on our bodies, what more do we need? I think we need to consider freeing ourselves from the weight of the chains of managing too many ventures. Personally, I plan on investing in no more than 5 simultaneous ventures ever, with the exception of some IRAs that I just plan to let sit for the next 20 years (and therefore no thought or anxiety required).

I just found your site & so far I like what I see. I am 50 years old & will be retiring at the end of Jan 2019. I turn 51 the following month. I will have a pension income of $60,000 per year & an additional $5,400 from a survivors benefit. I was able to save $200,000 in a deferred comp program through my employer & wish to know what to do to generate a passive income? I can leave it in the plan which will generate about 3.5% or invest it. My concern is the tax liability of taking out a large sum from that fund & leaving me less to invest. I do have an opportunity to invest in a bar/restaurant with family (my main concern) that currently generates $120,000 annually for an absentee owner. It would be a 3 way partnership if I did that. I do like your idea of creating my own product such a blog with a goal of $12,000 to $18,000 passive income I feel that may be my best option. Any thoughts or advice would be greatly appreciated.
