Real Estate Income – Since we moved up to Newport Beach, I started renting out my condo in San Diego. My monthly cash on cash return is $300(I charge $1,900 for rent and my total payments including mortgage, HOA, property tax and insurance are $1,600) but I also get back around $350 every month in principal and about a $150 tax savings per month. But even this income is inconsistent, since sometimes expenses will pop up like last month when I had to buy a new A/C for $3,000!

What I did: I first identified my favorite places in the world to live: San Francisco, Honolulu, Paris, Amsterdam, New York City, and Lake Tahoe. I then looked up the median rent and housing prices for each city. Then I factored in private education costs for two kids to be conservative given I may not have two kids and public schools are often good enough. After calculating all vital costs, I then did a self-assessment of how happy I was making $50,000, $100,000, $150,000, $200,000, $250,000, $350,000, $500,000, and $750,000. I decided working 20 hours a week making $200,000 a year is the best income balance for maximum happiness. 
The services sector has the largest share of India's GDP, accounting for 57% in 2012, up from 15% in 1950.[165] It is the seventh-largest services sector by nominal GDP, and third largest when purchasing power is taken into account. The services sector provides employment to 27% of the work force. Information technology and business process outsourcing are among the fastest-growing sectors, having a cumulative growth rate of revenue 33.6% between fiscal years 1997–98 and 2002–03, and contributing to 25% of the country's total exports in 2007–08.[194][needs update]
Passive income is defined by Wikipedia as “income resulting from cash flow received on a regular basis, requiring minimal to no effort by the recipient to maintain it”. And while the ‘no effort’ part of the definition is very enticing, the truth is that generating passive income requires a massive amount of effort. And this effort needs to be exerted up front and then sustained for months, and maybe even years, until your venture starts returning profits. And even then, you'll have to monitor your income streams to make sure it’s all going smoothly. It's certainly not an easy endeavour, no matter what most people may tell you, and it requires an investment of something far more valuable than money: time. But if you are up for it, then here are 14 ideas that you can use to start earning passive income.
Love your articles. I think everyone is very different as far as how much passive income they need to meet their goals. I’ve read a lot of your articles and really enjoy your thoughts. I have a masters in finance and understand the math of keeping the debt but my emotions are such that I need to try to finish off paying off my last debt (mortgage) in the next two years. At 34 and only worth 525k I’m doing better than a lot of folks my age but it will be difficult for me to catch up in the passive income game without leverage. That is the main reason I recently created a website to try to bring passive income opportunities in my area to me.
I also noticed that in your passive income chart at the bottom that you don’t include your internet income other than sales from your book. Is there a reason for that? Do you not consider is passive because you are actively blogging all the time to create it? Or do you just not want readers to know how much money you generate from blogging activities?
Inspired by you, I started a tax/personal finance a month ago. I figured if it works out, it will create a good side income for me. If not, at least I can use the blog to build my brand as a tax lawyer. Other than that, my current investment portfolio is heavily focused on index funds because of its historical performance and tax & cost efficiency. Right now my dividends income every year is about $14,000. I also have a good amount of unrealized capital gains every year from my investment, though I don’t count the capital gains as my passive income as they are paper gains, at least for now.
If you’ve been passionately collecting something over the years, this may well be your route to extra income. Be it comic books, records, stamps or even vintage clothing you picked up from second-hand stores, the chances are likely that there is someone out there who shares your passion. Whilst sites like eBay and Amazon are ideal for generic selling, if your collection consists of more niche items, you may need to use a more specific platform.
This is an interesting take and good advice for those who probably do not need to ever worry about becoming destitute. I’m sorry but too many of your options including your own list of income require quite a bit of initial investment/capital and these suggestions are useless to those living paycheck to paycheck. I’d like to see the average low to middle income household purchase additional property for rental, invest in their portfolio (if they can even start one), or even afford to have a vehicle or room to rent. Far too first world of a solution for the general public.
If you are expert in some area, you can always give your consultancy service to smaller businesses who cant hire big companies. When we were brainstorming with a client of ours to generate second line of income, he identified that he has some great knowledge in the area of terrace gardening. He could see that he can help families with large enough terrace to setup their own balcony garden and earn some fees over weekends or extra time.
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.
