India liberalised its FDI policy in 2005, allowing up to a 100% FDI stake in ventures. Industrial policy reforms have substantially reduced industrial licensing requirements, removed restrictions on expansion and facilitated easy access to foreign technology and investment. The upward growth curve of the real-estate sector owes some credit to a booming economy and liberalised FDI regime. In March 2005, the government amended the rules to allow 100% FDI in the construction sector, including built-up infrastructure and construction development projects comprising housing, commercial premises, hospitals, educational institutions, recreational facilities, and city- and regional-level infrastructure.[304] Between 2012 and 2014, India extended these reforms to defence, telecom, oil, retail, aviation, and other sectors.[305][306]
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!
The craziest part of this was I’d wake up in the morning and there would be more money in my bank account, from people who had bought my book overnight. When you think about it, an online store that sells something that’s digital is something that’s open 24 hours a day, 7 days a week, 365 days a year. Using tools, software and systems, you can automate the delivery process so you literally don’t have to do anything to serve that audience. That’s super powerful.

India has made progress increasing the primary education attendance rate and expanding literacy to approximately three-fourths of the population.[389] India's literacy rate had grown from 52.2% in 1991 to 74.04% in 2011. The right to education at elementary level has been made one of the fundamental rights under the eighty-sixth Amendment of 2002, and legislation has been enacted to further the objective of providing free education to all children.[390] However, the literacy rate of 74% is lower than the worldwide average and the country suffers from a high drop-out rate.[391] Literacy rates and educational opportunities vary by region, gender, urban and rural areas, and among different social groups.[392][393]

The best part is that you keep 97% of the fees paid and you don’t have to search for clients yourself . Serve them as they come. If you have a full house at some great tourist place like Goa/Shimla/Manali or those kind of places, you can put your whole house on rental basis. Many people who have a second home or extra room, hire a maid and offer the full range of services of a regular basis. Imagine if your extra room is rented even 5 times a month and you earn Rs 1,000 from it ? Its Rs 5,000 extra income !

Who cares, especially when very conservatively, the ultimate passive income includes a six digit or more base lease, plus an estimated additional six digits or more for rate increases and another six digits for more for various smaller and one bigger technology increase at 25 years. All four (base, rate, smaller and mega technology increases) combined, certainly could yield much more depending upon inflation, rate increases and technology increases?

The information technology (IT) industry in India consists of two major components: IT services and business process outsourcing (BPO). The sector has increased its contribution to India's GDP from 1.2% in 1998 to 7.5% in 2012.[213] According to NASSCOM, the sector aggregated revenues of US$147 billion in 2015, where export revenue stood at US$99 billion and domestic at US$48 billion, growing by over 13%.[213]
I enjoy how you lay out real numbers. A lot of people wouldn’t do that. While you admit that you are somewhat conservative, I think the $1M in CD’s is just too conservative. Assuming you don’t need the cash flow now (which you say you just save anyways) then all that could be invested for potentially higher returns. For example, what if you bought San Francisco real estate along the way instead of CD’s. Or, an SP500 Index fund. I bet your average return would have been higher than 3.75%. Sure you could lose it, but the point is if you don’t need the cash flow now, you should try to increase that nut as high as possible until the day you actually need it. Your nut could be $5M right now if you had invested in asset classes other than CD’s for the last 14 years. Don’t get me wrong, you have done far better than me, but I guess I would take a little more risk if you don’t rely on that cash flow.
These are most of the ways that I use to try and diversify my income. Add them all up and they’re still nowhere near my day job income but they’re getting closer every day. No matter how much you make it’s imperative to start thinking about additional ways to make money. Real estate and investing are some of the best passive sources of income but it’s also important to think of alternative active sources of income. For most people, those two things will never be able to equal your day job pay but secondary active sources could one day replace your day job whether you want it to or not.
The reverse can also be expected unless the rents rise too.  This rental increase might occur if we imagine interest rates are rising because the economic environment is improving.  At present, it is widely expected that rates will rise ever so slowly over many years.  Indeed the US has been looking for the courage to do this over recent months and they may start rising there soon.
