Good ranking FS, I’d have to agree with the rankings. And it looks like your portfolio covers five of the six! Some people consider real estate passive will others classify it as active. But every scenario is different, whether you are doing all the maintenance and managing yourself, or you are contracting out a lot of the work. Obviously it takes a lot more time and effort than purchasing a 36 month CD and “setting it and forgetting it.”
In equity valuation, residual income represents an economic earnings stream and valuation method for estimating the intrinsic value of a company's common stock. The residual income valuation model values a company as the sum of book value and the present value of expected future residual income. Residual income attempts to measure economic profit, which is the profit remaining after the deduction of opportunity costs for all sources of capital.
