The appeal of these passive income sources is that you can diversify across many small investments, rather than in a handful of large ones. When you invest directly in real estate, you have to commit a lot of capital to individual projects. When you invest in these crowdfunded investments, you can spread your money across many uncorrelated real estate ventures so individual investments don't cause significant issues.
In mid-2017, I sold my San Francisco rental property for 30X annual gross rent and reinvested $500,000 of the proceeds in real estate crowdfunding. I’m leveraging technology to invest in lower valuation properties with higher net rental yields in the heartland of America. With the new tax policy starting in 2018 capping state income and property tax deductions to $10,000 and limiting interest deduction on mortgages of only $750,000 from $1,000,000, expensive coastal city real estate markets should soften at the expense of non-coastal city real estate.
If you know anything well, a place, how to fix something, how to make something, how to do something, you can write a guide for it. You can sell your guide as an e-book, offer it as a download for a fee on your site or reach out to bloggers with similar content and ask if they will offer it as a paid download on their website (for a price of course).
Residual income is the best model for money generation. Once you master and build up one avenue, you can devote your time and money into another avenue. Eventually you start reaping the benefits of multiple residual income avenues. Enabling you to have complete financial and time freedom. I recommend to all people to build these types of asset models as they can greatly improve their life.
