Active residual income is income that you would participate more directly in creating, like sales. Although the initial effort to create the income has already been exhausted, you would still be active in the creation of the funds, resolving customer issues, taking care of finances, making sure products are always in stock or available, and researching money saving methods. This is the type of thing that you have to actually participate in to make money. This does not necessarily mean that the number of hours you put in directly correlate to how much money is made, but it does mean that this type of residual income is not money that is going to be made while you sit at home and think about it.
My favorite type of semi-passive income was rental property because it was a tangible asset that provided reliable income. As I grew older, my interest in rental property waned because I no longer had the patience and time to deal with maintenance issues and tenants. Online real estate became more attractive, along with tax-free municipal-bond income once rates started to rise.
Another option: Consider starting your own real estate investment group. This is a great way to team together with other small investors, either via pooling your money together or simply by learning from eachother. According to Joseph Hogue, CFA from PeerFinance101.com, “The common bond in all real estate investing groups is that you help each other compete against the big money players to get the best returns.”
If you're looking to get started in real estate, look at a crowd funding solution like RealtyMogul. It works similar to LendingClub - you commit as little as $5,000 towards a property. When the property is fully funded, you become an owner, and will receive your share of the earnings and appreciation in the property. Check out RealtyMogul to learn more.
