Additionally, at some point with the compounding model of adding low cost units, an investor stops being and investor and goes back to becoming a worker bee: a team must be created and actively managed, analysis on dozens if not hundreds of units must be done on an ongoing basis, additional deals must be found and closed, etc.I prefer the appreciation model because there are substantially fewer moving parts in the investment machine.
