1) Overview
Momentum identifies where permit activity accelerates relative to recent local baseline, not where absolute volume is highest.
Methodology Paper
Chicago Momentum Methodology
A concise framework for how Profentra computes area-level development momentum and where interpretation boundaries sit.
2) Data Sources
Primary source: Chicago Open Data Building Permits (Socrata). Records are normalized, deduplicated, and geocoded where necessary.
Open dataset3) Momentum Formula
For each area: compare 30-day permit activity against rolling 90-day baseline, then normalize to a bounded 0–100 score with permit-mix influence.
4) Limitations
Permit velocity can lead or lag pricing and may underrepresent off-market dynamics. Use alongside local underwriting context.
5) Update Cadence
Connector ingestion and momentum snapshots update daily. Weekly digest summarizes highest-momentum areas.
6) FAQ
Does high momentum always mean buy now?
No. It is an early signal for deeper diligence, not an investment instruction.
How should I compare neighborhoods?
Use momentum score with permit mix and trend direction, then validate by submarket fundamentals.
