Amazing that you saved between 50% to 75% living in NYC…I think that is one thing holding me back…the cost of living here. I’d like to invest in real estate, but I can barely afford to buy a place to live. I don’t need a large income to be happy, but I probably do need an income to support living in NYC as we don’t plan on leaving. The only thing I’m doing at the moment is saving in my 401K, IRA and a I dabble in stocks and P2P lending.
Inspired by you, I started a tax/personal finance a month ago. I figured if it works out, it will create a good side income for me. If not, at least I can use the blog to build my brand as a tax lawyer. Other than that, my current investment portfolio is heavily focused on index funds because of its historical performance and tax & cost efficiency. Right now my dividends income every year is about $14,000. I also have a good amount of unrealized capital gains every year from my investment, though I don’t count the capital gains as my passive income as they are paper gains, at least for now.

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.
