In the case of an activity with respect to which any deductions or credits are disallowed for a taxable year (the loss activity), the disallowed deductions are allocated among your activities for the next tax year in a manner that reasonably reflects the extent to which each activity continues the loss activity. The disallowed deductions or credits allocated to an activity under the preceding sentence are treated as deductions or credits from the activity for the next tax year. For more information, see Regulations section 1.469-1(f)(4).
Real estate crowdfunding presents a middle-ground solution. Investors have their choice of equity or debt investments in both commercial and residential properties. Unlike a REIT, the investor gets the tax advantages of direct ownership, including the depreciation deduction without any of the added responsibilities that go along with owning a property.
Have you developed a particular brand or system that others can benefit from?  The options here vary quite a bit.  For example the rock band Def Leppard is able to license their brand because of their massive success.  Or look at a college sports franchise like the UW Badgers, who have created an amazing brand around a great sports team (Go Badgers!), everything from t-shirts to coffee mugs.  All of these are potential sources of passive income, if you are the one that has created the brand or process of course!

Real-estate crowdfunding ($9,600 a year): Once I sold my SF rental, it was natural to reinvest some of the proceeds into real-estate crowdfunding to keep sector exposure. I didn't invest a lot in some of my favorite real-estate investment trusts because I felt a rising interest-rate environment would be a stronger headwind for REITs. But if I could be more surgical with my real-estate investments by identifying specific investments in stronger employment-growth markets, I thought I could do better.
I just wanted to say how nice it is to see such a positive exchange between strangers on the Internet. Seriously, not only was this article (list) motivating and well-drafted, the tiny little community of readers truly were a pleasant crescendo I found to be the cause of an inward smile. Thank you, everyone, and good luck to you all with your passive income efforts!! 🙂
