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).

Negotiation Leverage Score (0-100)
Based on 5 observable signals from the property's listing data:
- +30 pts: 15+ units currently listed
- +25 pts: Active move-in specials
- +20 pts: Deep discounts (>$150/mo off)
- +15 pts: 5+ distinct floor plans
