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.
Not bad to have some extra income! Also, when I’m traveling I rent out my entire place. I love generating income for not being home!  It doesn’t get much better than Airbnb as a form of passive income. It literally only takes 10-15 minutes to set up and you can generate rental income from your property with the click of a button. Pair this with credit card churning to travel and you are making more money than you are spending. Talk about getting paid to travel! Put your extra space to work on Airbnb!
Nobody gets early FI investing in bonds, CD’s, or even stocks unless they make a huge income or are extremely frugal or a combination of both. Paper assets just don’t provide enough returns. Business income can be great but it is typically not as semi-passive as I would like and there is a relatively high failure rate. That is if you can monetize an ideal to begin with. RE investing needs to be higher ranked IMO as a way that the “average guy” can become FI.

There are basically three types of income: earned, portfolio, and passive. When it comes to filing your tax return, each of these types of income are taxed differently. Therefore, it is worth understanding the difference between the three to minimize your tax burden. Below are the three types of income, how they are categorized, and the tax implications for each.
I have only dabbled in drop-shipping before when I had an eCommerce platform 6 years ago or so. I think it is something that you could do on the side, but you would want to do in depth research on the industry you want to get into before setting up shop. It may be a little less passive up front, but over time you could take your hands off the wheel.
