1) If your property is not under rent control, you have the ability to raise rent to market prices with proper warning. In SF, I have to give tenants a one month warning for up to a 10% increase and a two month warning for up to 60%. Rent control limits to an inflation index, usually around 2% a year, which is why initial pricing and tenant turnover is important for better profitability.
We pitched to an angel investor group. They were very excited about the idea but wanted to know who amongst us (doctor, accountant, salesman) was doing the coding. When they heard we were outsourcing it, the wind went out of their sails immediately. They did want to meet with us again once we brought a coder on board but that person proved elusive to find. Coders in our area are looking for the steady paycheck, not willing to gamble on a startup.
Income from the performance of services directly related to the use of a vessel or aircraft is treated as derived entirely from sources in the United States if the use begins and ends in the United States. This income is subject to nonresident alien withholding if it is not effectively connected with a U.S. trade or business. If the use of a vessel or aircraft either begins or ends in the United States, refer to Transportation Income in Publication 515, Withholding of Tax on Nonresident Aliens and Foreign Entities.
That $200,000 a year might sound like a lot to you, but the median home price in San Francisco is roughly $1.6 million or almost eight times our annual passive income. For a family of three in 2018, the Department of Housing and Urban Development declared that income of $105,700 or below was "low income." Therefore, I consider us firmly in the middle class.

2) Find Out What You Are Good At. Everybody is good at something, be it investing, playing an instrument, playing a sport, communications, writing, art, dance and so forth. You should also list several things that interest you most. If you can combine your interest plus expertise, you should be able to monetize your skills. A tennis player can teach tennis for $65 an hour. A writer can pen her first novel. A finance buff can invest in stocks. A singer can record his first song. The more interests and skills you have, the higher chance you can create something that can provide passive income down the road.
You can select any of the above-mentioned, based on your interest, skill, and capability to generate a second income source. However, these are just to name a few, there exists multiple ways to generate secondary income channel. You just need to identify the right one, which suits you the best. Remember there is no shortcut to success and you need to work hard to be successful and rich in the long run!
There are many success stories you’ll run into of what it takes to generate multiple streams of income. However, one of the most important tips is to take on multiple clients. One client being your income source is bad news. They could voluntarily or involuntarily leave you high and dry. For instance, their business may begin to suffer and they no longer have the funds to pay you. Well, that is your income stream; gone without warning.
I like to think about having an additional source of income as being sort of like an insurance policy. I interviewed one young woman who taught aerobics classes in the evenings after spending her days working as a videographer for news organizations. When she was unexpectedly laid off from her day job, she quickly doubled her aerobics teaching load and was able to keep herself afloat until she found a new full-time job. Some more examples of income multi-streaming are a teacher I know who sells used baby clothes out of her home and a young couple who run a small Internet business on the weekends. Just like these people, you can also pick a profitable project or create a business that matches your lifestyle. 
​Self Publishing is mainstream today. When you purchase an eBook off of Amazon there’s a pretty good chance you’re buying a self-published book. Self-publishing is also ridiculously easy. I tried this a few years ago and couldn’t believe how simple the process was. To self-publish a book you’ll first need to write and edit it, create a cover, and then upload to a program such as Amazon’s Kindle Direct Publishing. Don’t expect instant success though. There will need to be a lot of upfront marketing before you can turn this into a passive income stream.
For those willing to take on the task of managing a property, real estate can be a powerful semi-passive income stream due to the combination of rental and principal value appreciation. But to generate passive income from real estate, you either have to rent out a room in your house, rent out your entire house and rent elsewhere (seems counterproductive), or buy a rental property. It’s important to realize that owning your primary residence means you are neutral the real estate market. Renting means you are short the real estate market, and only after buying two or more properties are you actually long real estate.
