Estimated Building Revenue

How is this calculated?

Rental revenue model

We follow each unit's listing activity at this building every day. When a unit stops being listed, we assume it leased at its last listed rent, adjusted for any advertised move-in special. Revenue is the sum of those assumed lease rents across the building's occupied units.

Building size: modeled from how many distinct units we have observed over time
Occupancy: building size minus currently listed units
Rents: observed lease-offs first, current asking rents as fallback

These are research estimates, not financial statements from the operator. Confidence: moderate (building size is modeled).

+25 pts: Active move-in specials
+20 pts: Deep discounts (>$150/mo off)
