The Art of Subtraction: Using ‘Inversion’ to Prune Your Portfolio
In real estate, we are culturally programmed to be "Hunters." We measure success by the door count and the acquisition. But the investors who compound wealth over decades don't just focus on being brilliant—they obsess over not being stupid. In this post, we apply Charlie Munger’s mental model of "Inversion" to real estate. We move beyond the flawed "would you buy at market?" question and replace it with the Cash vs. Keys test. We also quantify the economic cost of "Brain Damage" by calculating your Return on Energy. True optimization isn't about adding complexity. It's about the ruthless clarity of subtraction.
