The record, not a score.
Vendors hand you a distress score and hide the inputs. Siboga gives you the docket, the unpaid bill, the permit application, and the assessor record, joined on one parcel. You decide what they mean together.
Public-record property evidence
Property evidence you can check.
Foreclosure filings, tax delinquency, scheduled auctions, building permits, and parcel assessments, pulled directly from the public record and joined on one timeline per parcel. Every field carries its source link and the time we observed it.

Built for diligence
Incumbents sell breadth. Siboga sells the record.
Two clocks on every row.
Event time is when the court, tax office, or building department acted. Observation time is when we fetched the page. Backtests and audits need both, so both are stored.
Gaps stated as plainly as coverage.
Each source names what it dropped. An unreadable or truncated page fails the run and appears in its receipt. If the provenance is missing, the field is not in the dataset.
Raw evidence kept, write once.
The original page is archived with a SHA-256 hash before anything is parsed. Any normalized row can be rebuilt from the raw object it points to.
Signals
Public-record signals, one parcel timeline.
Foreclosure filings
Judicial foreclosure cases by property address, with docket, plaintiff, and case status, linked to the court record.
Scheduled auctions
Court-posted foreclosure sales with sale date, sale type, and deposit, linked to the posting.
Tax delinquency
Unpaid installments read from each town bill detail page, with due dates and the bill link. Attributed by parcel, never by a shared address.
Building permits
Permit applications with type, description, and declared cost, joined to the parcel. Applicant contact fields are stripped.
Parcel assessments
Assessor records with use code, living area, owner of record, and absentee flag, joined on parcel ID first and address last.
Delivery
Delivered where diligence happens.
Pinned snapshots
A CSV export with a manifest: snapshot ID, SHA-256 of the file, and row count. Nothing is published without an identified snapshot.
Evidence dossiers, by engagement
A bounded answer to one asset or ownership question: source ledger, claim grades, the paths searched, and the paths not searched. Negative findings always carry their denominator. Scoped and priced per question.
Private API stream, planned
A read-only stream of a pinned snapshot, one token per consumer, arranged per customer. Not yet serving; ask before you plan an integration around it.
Questions people search for
Answers grounded in the sources.
- How do I find pre-foreclosure properties in Connecticut?
- Connecticut foreclosures are judicial, so every case is filed with the Judicial Branch and searchable by property address. Siboga collects those filings statewide, joins each one to the assessor parcel record, and keeps the docket link on the row so you can open the case yourself.
- How do I check whether a property has delinquent taxes in Connecticut?
- There is no statewide list. Each town runs its own tax portal. Siboga reads the bill detail page for each parcel, records the unpaid installments and their due dates, and links the bill. A town is only marked complete when every eligible parcel has an outcome.
- Where do foreclosure auction dates come from?
- From the Judicial Branch foreclosure sale postings, town by town. Siboga records the sale date, type, and deposit and links the notice, then matches it to the foreclosure case by docket.
- How do I find out who owns a property?
- The assessor record names the owner of record and the mailing address. Siboga carries that owner on every joined row, flags absentee ownership when the two addresses differ, and never adds phone numbers or emails.
- Can I get building permit data by address?
- For the municipalities Siboga collects, yes. Permit ID, application type, description, and declared cost come joined to the parcel, with the portal link. Coverage is listed town by town on the coverage page.
- Is the data licensed from a vendor?
- No. Every source is a public record fetched directly, without an account or an API key. Posted terms and access conditions are recorded as metadata for each source, and the raw response is archived before it is parsed.
The name
Named for H.M. Siboga.
The Dutch gunboat Siboga sounded the deep basins of the Indonesian archipelago in 1899 and 1900. Its expedition took decades to publish, one monograph at a time, each with lithographic plates drawn from the specimens. The plates on this site come from the 1901 volume on holothurians. They are in the public domain, and their provenance is recorded in the repository beside the data provenance.
The method is the point: collect carefully, record where every specimen came from, and publish what was found and what was not.
