The age old argument of total return versus income has been, incorrectly imo, categorized as an either or proposition. We are going to do both. Right now I have a lot cash in an on line money market. I also have investments in 2 passive Index funds in a taxable account. We then have substantial 401ks/IRA’s which we won’t touch for at least 10 years. My wife will continue to max out her sep and we will continue to invest in the index funds although with a smaller amount. We have already factored that in. I looked at how to cut into the monthly deficit. Here is what I observed.
For those willing to take on the task of managing a property, real estate can be a powerful semi-passive income stream due to the combination of rental and principal value appreciation. But to generate passive income from real estate, you either have to rent out a room in your house, rent out your entire house and rent elsewhere (seems counterproductive), or buy a rental property. It’s important to realize that owning your primary residence means you are neutral the real estate market. Renting means you are short the real estate market, and only after buying two or more properties are you actually long real estate.

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.
