## Property Intelligence

How is this calculated?

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

- +10 pts: 25+ units listed

All signals come directly from the property's own listings. Occupancy and building size appear only in the Estimated Building Revenue section, and only when the building size is stated by the property or our unit-level observation history is deep enough to model it.

Listed Units

24

Good availability

15 floor plans

Move-in Specials

0

No active promotions

Negotiation Leverage

Moderate leverage

Some signals suggest room to negotiate, especially if you can be flexible on move-in date.
