This may be a method that is unusual. Drive traffic to your lens the same as you would your blog. Link to your lens on social media platforms, like Twitter. The more people that know about the lens, the more that are apt to visit and purchase. The lens can also be used to promote products on e-bay or CafePress. Write a short description of the product and its unique uses and sell away.
My returns are based on full cash purchase of the properties, as it is hard to compare the attractiveness of properties at different price ranges when only calculating down payment or properties that need very little rehab/updates. I did think about the scores assigned to each factor, but I believe tax deductions are a SIGNIFICANT factor when comparing passive income steams.

If you don’t have an IRA or 401K, then not only are missing out on a great opportunity to earn passive income, but you are likely paying way more in taxes than you should be as well. By opening an IRA with Betterment, you can save up to $5500 of income without having to pay income taxes on that money. Betterment will then automatically invest that money for you using their proven investment strategies.

Now I’ve been using Swagbucks for a while and have found the money works out to just under $2 an hour so this isn’t something that’s going to make you rich. You’d have to work 2,500 hours to make $5,000 so that’s about three and a half months, non-stop. The thing with Swagbucks though is you can do it when you’re doing something else so I flip through surveys and other stuff while I’m cooking dinner or flipping channels.
But when so many turn down leasing one and one-half acre for one Wind Turbine for each 80 acres, that lease certainly does not materially affect the rest of the Farm or Ranch grazing pasture and the lease pays much more than the farm crow or grazing pasture lease, just because some lawyer said the lease was too long: 30 years plus 30 year option = 60 years, and the wind turbine company has selling production/electricity contracts for the next 150 years – which is needed to obtain financing!
Buy a small business: A local small business, like a car wash or a laundromat, is a great way to put money down on a money-making venture. Automate it so you don't have to be on the premises unless you're collecting money. Go into a local business with your eyes wide open - study the books, especially on income and expenses, and examine water and utility bills if your venture will be open 24 hours.
Residual income is the amount of net income generated in excess of the minimum rate of return. Residual income concepts have been used in a number of contexts, including as a measurement of internal corporate performance whereby a company's management team evaluates the return generated relative to the company's minimum required return. Alternatively, in personal finance, residual income is the level of income that an individual has after the deduction of all personal debts and expenses have been paid.
