PropertyShark — Pros & Cons

Pros

Best-in-class NYC property data with 180+ data points including air rights, zoning, and FAR calculations
LLC/entity owner penetration at Platinum tier helps investors reach real decision-makers behind shell companies
Pre-foreclosure and foreclosure pipeline sourced from public records across 1,200+ counties nationwide
One free full property report available without a credit card to evaluate data quality before subscribing

Cons

Geographic depth heavily skewed toward New York — residential coverage outside the Northeast is inconsistent and patchy
No client-facing presentation layer: raw data tables, not polished CMA reports for buyer or seller meetings
Platinum tier required for LLC owner lookup pushes the monthly cost to $169.95 — steep for occasional investors
No MLS integration — all data is sourced from public records, which can lag live listing activity by days or weeks
