Analyst’s Manifest

Every study outputs a complete table of assumptions and inputs — ready for your underwriting model.

Pro Forma Builder

Deep Dive

The Analyst's Manifest

Every zoning study auto-generates a Manifest — a structured table of every assumption, input, and calculation your deal team needs to build a pro forma without re-entering a single number.

Buildable SF by scenario

Unit mix and floor counts

Parking requirements and strategy

FAR utilization and bonus eligibility

Height and setback constraints

Tax program eligibility and benefits

Construction cost assumptions by type

Revenue assumptions by use group

Industry first

Pro Forma Builder

The Manifest feeds directly into the Pro Forma Builder. Development costs by building type, financing structure, and returns modeling — all computed instantly. No other platform in NYC does this.
