You need to decide which machines you want to run, get the necessary licenses to operate them (you're selling items so you need to get sales licenses and whatnot from your state), buy the machines and a truck for the items in the machines, find a supplier of the products, and then finally you can secure locations. Finally, you need to service them periodically or hire someone to service them.

Investing in rental properties is an effective way to earn passive income. But it often requires more work than people expect. If you don’t take the time to learn how to make it a profitable venture, you could lose your investment and then some, says John H. Graves, an Accredited Investment Fiduciary (AIF) in the Los Angeles area and author of “The 7% Solution: You Can Afford a Comfortable Retirement.”
Just like any industry, there is good and not so good. The good part of passive income is that it can lead to multiple streams of revenue. Entrepreneurs understand more income sources means a more stable business and more room to grow. Implementing passive income strategies creates exciting possibilities and opportunities. Passive income sources allow me to have freedom and financial security in my life and business. I can spend my time traveling or writing, knowing that I'm stilling making income.
2007 Human Development Report (HDR), United Nations Development Program, November 27, 2007, p.25. (The report also notes that although India is rising economically, the bad news is that this has not been translated into accelerated progress in cutting under-nutrition. One-half of all rural children [in India] are underweight for their age—roughly the same proportion as in 1992.)
From 2000 to 2010, the country attracted $178 billion as FDI.[307] The inordinately high investment from Mauritius is due to routing of international funds through the country given significant tax advantages – double taxation is avoided due to a tax treaty between India and Mauritius, and Mauritius is a capital gains tax haven, effectively creating a zero-taxation FDI channel.[308] FDI accounted for 2.1% of India's GDP in 2015.[11]
P.S. I also fail to understand your fascination with real estate. Granted we’ve had some impressive spikes along the way, especially with once in a life time bubble we just went through. But over the long term (see Case Shiller real estate chart for last 100 years ) real estate tends to just track inflation. Why would you sacrifice stock market returns for a vehicle that historically hasn’t shown a real return?
Estimated GDP per capita of India and United Kingdom during 1700–1950 in 1990 US$ according to Maddison.[97] However, Maddison's estimates for 18th-century India have been criticized as gross underestimates,[98] Bairoch estimates India had a higher GDP per capita in the 18th century,[99][100] and Parthasarathi's findings show higher real wages in 18th-century Bengal and Mysore.[101][78] But there is consensus that India's per capita GDP and income stagnated during the colonial era, starting in the late 18th century.[102]
Doesn’t it sound awe-inspiring to have more than one income source? You already have one source of work with a steady flow of income and then you are creating more and more work for you with more income for you. Who does not want to have lots of money in their bank accounts floating all around? For the person who values financial security and their ultimate dream is financial freedom, creating more than one source of income becomes a necessity not just desire.

What I find most interesting is the fact that I had never considered options like LendingTree or realityshares for other income sources. Investing in property has been too much of bad luck for people that I know personally, so I am interesting in getting involved in a situation where I would have to be dealing with maintenance issues or tenants. There are services for you to do that, but I had not come across any that didn’t eat most if not all of the earnings. Then again, I live in the NY area. Investing in the midwest would not be reasonably possible for me, directly, but reading about realityshares is something I am going to look into further. That might be a real possibility.
Since I knew I’d eventually be losing my day job income, I had to set realistic goals. There was no way I was going to make a six figure salary blogging and working online after only 2 years but I thought it might be possible to cover our monthly expenses for a few months while I took time off and looked for a new job. I already had some secondary sources of income and there were others that I specifically tried to build up.
An obvious example is over exposure to bank stocks, which have been excellent investments for over a century.  Though a foundation of most portfolios, bank stocks do involve more risk at certain stages of the economic cycle than many realise.  Being less exposed to bank shares in the last few months could have preserved some capital.  So, a more diversified approach can help mitigate some of these risks.
