Purchasing a rental property is another common way that individual generate an income stream.  It is very similar to investing, in that you take a sum of money to purchase the property, and the property returns a cash flow – rent.  You do have expenses related to this that are different from investing, such as a mortgage, utilities, property taxes, etc, which all must be taken into consideration when calculating a return on rental property.
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.
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.

Obviously, these are much higher than you’re going to get with most other investments. What’s more is that you can choose a plan that matches your investment strategy, whether your goal is Supplemental Income, Balanced Investing, or Long-term Growth. You can also look at different real estate projects and choose for yourself which ones to invest in.

ie first you need to haul ass and do something crazy, eg write a quality 20,000 word ebook (insanely not passive hahahah), but then you get to sit back and enjoy seeing PayPal sale messages pop up on your iPhone each morning as sale after sale after sale is made…on an ongoing basis and without any additional work. That’s some seriously Pina Colada flavored passive goodness!

These days, low-risk bond yields aren’t enough to meet most income needs. When investing in bonds, the income typically comes as coupon payments – contractually guaranteed interest payments at predictable intervals.  There are many kinds of bond income available, so you must strike a balance between reaching for higher income (yield) and limiting risk.
