After these tenants move out, I'm thinking of just keeping the rental empty with furniture. It sounds stupid to give up $4,200 a month, but I really hate dealing with the homeowner association, move-in/move-out rules, and maintenance issues. Given that the condo doesn't have a mortgage and I have to pay taxes on some of the rental income, I'm not giving up that much. The condo can be a place for my sister, parents, or in-laws to crash when they want to stay in SF for longer than a week or two.
Well, my first book project didn’t generate the interest I would have liked to, but another set of products suredid. In 2013, I launched a course on Udemy, which grew so fast, it became my biggest income earner of all time. That course resulted in a series of books (audio, digital, and print), a not-so-passive podcast, and even lead to my now full-time gig: SuperLearner Academy. Though I run the company full time, it is, for all intents and purposes, an automated business.
If you have specialized knowledge in a certain topic, you can put together an online course to teach others. For example, if you have experience in real estate investing, you can create an online course “Real Estate Investing 101”. The benefit of an online course is that once you create the course material, you can sell it to as many people as you want.
