For researchers & nonprofits
Parcel-level evidence for vacancy and ownership work.
Sourced and dated
Every value carries its source and vintage. Changes are kept as snapshots, never overwritten, so you can show what changed and when.
Transparent scoring
A documented, adjustable model scores distress from public records, with the evidence for each point. Tune the weights to your own definitions.
Export everything
CSV and PDF exports of the register, owner portfolios, and field activity, ready for analysis or grant applications.

The pattern behind the parcels.
A dated register of every parcel, questions answered with the parcels they came from, and a source and date on every flag, so findings hold up in a report or a grant application.
New: public records
One parcel. Every public record.
A dated event history from several agencies, already joined to the right parcel: non-arms-length transfers, foreclosure registrations, 311 requests, permits, flood exposure, and program-area membership. Filter it, map it, export it, and cite every source.
- Sales history
- Foreclosure filings
- 311 complaints
- Building permits
- FEMA flood zones
- State program areas
- Building footprints
- Notices of intent
Included on every plan. Foreclosures, permits and 311 are Prince George's County today; the rest is statewide.
