Investing in a business: Another good way to generate passive income is to invest in a business --even a small one -- in return for a percentage of the profits - just like Shark Tank, only smaller. Lending $10,000 to a local business that, for example, is working on a mobile app for Apple phones could lead to a passive income-generated share of the profits when that mobile app starts selling like hot cakes.
In identifying the items of deduction and loss from an activity that aren’t disallowed under the basis and at-risk limitations (and that therefore may be treated as passive activity deductions), you needn’t account separately for any item of deduction or loss unless such item may, if separately taken into account, result in an income tax liability different from that which would result were such item of deduction or loss taken into account separately.
Income tax is a cost of doing business and that cost carries over into the business of real estate ownership and operations. In July 2017, in the depths of the summer, the Federal Department of Finance (“Finance”) announced drastic changes that would have changed that cost of doing business for those owning shares of a Canadian controlled private corporation (“CCPC”). When ultimately distributed to the individual shareholder in the form of a dividend, investment income earned on the retained earnings generated from an active business would have cost the shareholder an ultimate income tax rate equal to 73% of the investment income. These proposed changes to the “passive income” rules were very complex and would have had the potential to shift the after-tax return for CCPCs while leaving the tax burden of public corporations, foreign corporations and tax-exempt entities unaffected.
Unfortunately, I can’t answer that conclusively one way or the other. It all depends on you, what you like to do, your work ethic, personality, etc. If you are a good writer perhaps you could write a book and make money that way. Or, you could start your own website and do affiliate marketing. Just because you are young it doesn’t mean you can’t make money doing at least a few of these ideas. I wish you luck in your money making efforts!
Index funds provide you with a way to invest in the stock market that is completely passive. For example, if you invest money in an index fund that is based on the S&P 500 Index, you will be invested in the general market, without having to concern yourself with choosing investments, rebalancing your portfolio, or knowing when to sell or buy individual companies. All that will be handled by the fund which will base the fund portfolio on the makeup of the underlying index.

In expensive cities like San Francisco and New York City, net rental yields can fall as low as 2%. This is a sign that there is a lot of liquidity buying property for property appreciation, and not so much for income generation. This is a riskier proposition than buying property based on rental income. In inexpensive cities, such as those in the Midwest, net rental yields can easily be in the range of 8% – 12%, although appreciation may be slower.
If the property in the syndication was held for at least a year, the gain will be treated as long term capital gain subject to 15%/20% capital gains rate.  Any depreciation taken on the property is subject to recapture and taxed at 25%.  The issuance of a K-1 usually results in a taxpayer needing to extend their individual tax return as most K-1s are not sent out until after the regular due date April 15.
