Newbrook refuses to invest unless the cap rate exceeds the borrowing cost from day one. This serves as a critical self-discipline, preventing speculation on future appreciation and guaranteeing that the asset generates a positive cash-on-cash return immediately, thereby de-risking the investment from the start.

Tech giants are shifting from asset-light models to massive capital expenditures, resembling utility companies. This is a red flag, as historical data shows that heavy investment in physical assets—unlike intangible assets—tends to predict future stock underperformance.

Real estate owners were skeptical of new tech. Instead of focusing on operational cost savings, Metropolis's go-to-market strategy centered on proving they could capture more revenue by eliminating leakage (e.g., when gates are up), which directly increased the underlying value of the real estate asset.

The housing industry is resistant to startup disruption due to immense "activation energy." This includes hyper-local regulations, fragmented distribution, cyclical capital needs, and a complex web of legacy players. Overcoming this barrier requires decades of effort, creating a powerful moat for incumbents.

Construction projects have limited upside (e.g., 10-15% under budget) but massive downside (100-300%+ over budget). This skewed risk profile rationally incentivizes builders to stick with predictable, traditional methods rather than adopt new technologies that could lead to catastrophic overruns.

New rent control laws don't just limit rent; they fundamentally cap the equity upside for real estate investors. By limiting potential cash flow growth from an asset, these policies make building or upgrading apartment buildings less attractive. This discourages the very capital investment needed to solve the housing supply crisis.

Companies like Amazon (from books to cloud) and Intuitive Surgical (from one specific surgery to many) became massive winners by creating new markets, not just conquering existing ones. Investors should prioritize businesses with the innovative capacity to expand their TAM, as initial market sizes are often misleadingly small.

Despite billions in funding for startups like Katera, the concept of mass-producing homes in factories has repeatedly failed. The construction industry's inherent need for site-specific customization and its complex value chain prevent it from achieving the efficiencies of scale and standardization seen in other manufacturing sectors.

Unlike industrial firms, digital marketplaces like Uber have immense operational leverage. Once the initial infrastructure is built, incremental revenue flows directly to the bottom line with minimal additional cost. The market can be slow to recognize this, creating investment opportunities in seemingly expensive stocks.
