Modeled recovery range per building: ~$5.9K-$35.3K/year

Modeled from a 200,000 SF building using IREM office opex benchmark ($11.15/SF in 2023), CPI-adjusted to 2025 dollars, and scenario leakage rates of 0.25%-1.5%. This is an assumption-driven estimate, not a universal outcome claim.

Modeled ROI range: ~25x to ~50x at $699/audit

Calculated from modeled recovery range versus per-audit cost ($699/audit, 1–5 tier). For a mid scenario (0.75% leakage, ~$17.7K recovery), modeled ROI is ~25x. Actual ROI depends on lease structure, CAM pool size, and data quality.

Modeled building value impact range at 7% cap rate

Using the modeled recovery range ($5.9K-$35.3K), the implied value lift at a 7% cap rate is roughly $84K-$505K per building. Actual cap rates vary by market and asset type.

Modeled portfolio leakage range

Portfolio estimates should be modeled from each property's CAM pool and scenario rates rather than a fixed per-building average.
