You can select any of the above-mentioned, based on your interest, skill, and capability to generate a second income source.

It is very important to understand that contacting a “professional” to learn how to do this only results in them trying to sell me crap properties (whether high end or low end). I’ve tried contacting realtors out of state, and they attempt to sell me crap or someone else’s problem. No one has a vested interest in actually helping someone or teaching them about how to get an out of state rental. very frustrating. I could go out tomorrow and buy a rental in my city, but that is the last place I want to own one. Anyone? Are there an real people on here?
Investing in real estate: Investing in real estate offers more passive income cash potential - but more risk - than investing in stocks or bonds. You'll need substantial amounts of cash to invest in buying a home -- it usually takes 20% down to land a good home mortgage loan. But history shows that home prices usually rise over time, so buying home a for $200,000 and selling it for $250,000 over a five-year time period, for example, is a reasonable expectation when investing in real estate.
There are a couple of problems with direct investment in real estate though. It’s expensive to buy even a single property, a minimum of tens of thousands of dollars, and there’s no way most investors can build a portfolio of different property types and in different regions to protect from those risks when you have all your money in just one or two investments.
I’ve built several businesses since 2008 using one or more of these models. I’ve been featured in magazines and articles across the globe, and since I started my journey I’ve generated over $5M in earnings from these businesses. All of my income and expenses for those businesses dating back to October 2008 have been tracked publicly on You can see 10 years of income reports here.
2. Focus on income-producing assets. Internet growth stocks may be sexy, but they provide no income. To build a large enough passive-income stream to survive, you must invest in dividend-generating stocks, certificates of deposit, municipal bonds, government Treasury bonds, corporate bonds, and real estate. You're free to invest in non-income-producing assets for capital appreciation too. You just want to earn reliable income when the day comes to leave your job.
What I Do: I’ve set up multiple investment accounts outside my main operations bank that deals with working capital e.g checking, paying bills. By transferring my money to a couple brokerage accounts and two other banks as soon as it hits my main bank I no longer have temptation to spend on frivolous things. As a result, I can wake up 10 years later and reap the rewards of compounding. My 401(k) is the best example where constant contributions over 18 years has grown to over $500,000 without any savings pain given it just became a part of life. Real estate is also a fantastic asset class for the long term. It’s fantastic to enjoy your home, pay down your mortgage each month, and end up with a paid off asset that has likely appreciated during your time of ownership. 
In the early 18th century, the Mughal Empire declined, as it lost western, central and parts of south and north India to the Maratha Empire, which integrated and continued to administer those regions.[85] The decline of the Mughal Empire led to decreased agricultural productivity, which in turn negatively affected the textile industry.[86] The subcontinent's dominant economic power in the post-Mughal era was the Bengal Subah in the east., which continued to maintain thriving textile industries and relatively high real wages.[87] However, the former was devastated by the Maratha invasions of Bengal[88][89] and then British colonization in the mid-18th century.[87] After the loss at the Third Battle of Panipat, the Maratha Empire disintegrated into several confederate states, and the resulting political instability and armed conflict severely affected economic life in several parts of the country – although this was mitigated by localised prosperity in the new provincial kingdoms.[85] By the late eighteenth century, the British East India Company had entered the Indian political theatre and established its dominance over other European powers. This marked a determinative shift in India's trade, and a less-powerful impact on the rest of the economy.[90]
Based on my initial experience of passive income, I feel real that real estate is best vehicle to build long-term investment. I live in Los Angeles and was able to cash flow my first rental property. What are you thoughts about starting out to build a passive income portfolio? I have utilized Lendingclub, online savings, and a small dividend/bond portfolio.

India's current account deficit reached an all-time high in 2013.[298] India has historically funded its current account deficit through borrowings by companies in the overseas markets or remittances by non-resident Indians and portfolio inflows. From April 2016 to January 2017, RBI data showed that, for the first time since 1991, India was funding its deficit through foreign direct investment inflows. The Economic Times noted that the development was "a sign of rising confidence among long-term investors in Prime Minister Narendra Modi's ability to strengthen the country's economic foundation for sustained growth".[299]
I want to develop a passive income stream in the next 4 years, nothing grand, maybe an extra 500-1000 dollars a month, but I’m not sure how to go about it so I was wondering if you had any tips. I’m so-so as a writer, and am currently finishing up my second book (just write as a hobby), and in the past made about 30-50 dollars an hour as a free lance writer but that was a couple of years back, it was only for about 10-20 hours a month, and the gig just dried up. I just got particularly lucky with that. I’ve tried online poker as a means in the past, and which I learned A) was not passive income but hard work and B) I have an addictive personality which resulted in me losing the 4g I earned in 6 weeks over the span of 72 hours so that’s out of the picture. I also partook in some illegal selling of things when I was younger, but being a little older and wiser the risk-reward ratio for possibly ending up in Jail just doesn’t match up. I tried making three businesses (dog walking, house cleaning, and personal assistant) and while those all were succesful to varying degrees and earned me about 15-25 dollars an hour, they weren’t mobile and quiet honestly I don’t have the time to be a full time dog walker or run a house cleaning operation seeing as I’ll be in school, work, and athletics.
If you need cash flow, and the dividend doesn’t meet your needs, sell a little appreciated stock. (or keep a CD ladder rolling and leave your stock alone). At the risk of repeating myself, whether you take cash out of your portfolio in the form of “rent”, dividend, interest, cap gain, laddered CD…., etc. The arithmetic doesn’t change. You are still taking cash out of your portfolio. I’m just pointing out that we shouldn’t let the tail wag the dog. IOW, the primary goal is to grow the long term value of your portfolio, after tax. Period. All other goals are secondary.

The government de-regularised the civil aviation sector in 1991 when the government allowed private airlines to operate charter and non-scheduled services under the 'Air Taxi' Scheme until 1994, when the Air Corporation Act was repealed and private airlines could now operate scheduled services. Private airlines including Jet Airways, Air Sahara, Modiluft, Damania Airways and NEPC Airlines commenced domestic operations during this period.[197]

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]
Capital growth in your portfolio can offset the eroding effect of inflation.  But any capital gains that exceed the overall inflationary effect can be drawn off to augment your portfolio income.  Of course, you must first generate those gains by making thoughtful investment selections.  While allowing strongly growing assets to keep doing that, it is prudent not to allow them to become a dangerously large part of your portfolio lest they go off the boil.  So if you selectively trim profitable positions along the way, you can boost your income.
