I’ve now only got a SF rental condo and a Lake Tahoe vacation rental in my real estate rental portfolio. Although I miss my old house, I certainly don’t miss paying $23,000 a year in property taxes, another mortgage, dealing with leaks and managing terrible tenants. I drove by the other day and couldn’t believe how much noisier and busier the street was than where I currently live. I wouldn’t be comfortable raising my son there.

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.
