Running property — leasing, maintenance, taxes, management — is the part of the business a REIT genuinely controls.

How is the moat score calculated?
Each company is scored with an industry-specific template — REIT Specialized in this case, chosen because the defenses that matter to a bank are not the ones that matter to a software company. Every defense combines several financial signals, and each signal is measured as a percentile against a peer group of 30 companies in REIT - Office. The defenses are then weighted to produce the overall score out of 100.
Why is SL Green Realty Corp scored with the REIT Specialized template?
A REIT is a portfolio of buildings financed with debt and required to distribute most of its taxable income. Reported earnings are dominated by depreciation on assets that often appreciate, so net income says very little; the real question is how much cash the properties distribute, and how securely. The REIT template scores what determines that: rent pricing, distributable cash, cost of capital, and the discipline behind growth.
Which competitive defenses are measured for SL Green Realty Corp?
The REIT Specialized template measures 6 defenses, and SLG scores: Rent Pricing Power (45), AFFO Strength (18), Balance Sheet & Cost of Capital (39), Capital Recycling & Growth (68), Operational Efficiency (32), Portfolio Quality & Diversification (64). Each is scored independently as a percentile against peers, so a company can be strong on one and weak on another — the overall score reflects how those defenses are weighted for this industry.
