The CurbScoop dataset
The listing tells one story. The sale, the building and the block add the rest. CurbScoop brings NYC property data together so you can understand what sits behind an address.
Core property analysis focuses on Manhattan and Brooklyn. Geographic coverage and available history vary by source; some neighborhood datasets extend across all five boroughs.
How the pieces fit together
NYC identifiers anchor the match. Apartment details help distinguish units within a building.
Nearby observations connect by location. A record near a building is not automatically a record about that building.
Eight complementary layers of property context
The marketed property
Observed asking prices, listing attributes and price changes provide context alongside recorded sales.
SourcesSupported listing and brokerage sources; retained StreetEasy history
StreetEasy collection has stopped; retained observations are historical. An asking price or reported contract status is separate from a recorded closing.
The transaction record
Deeds, transfer records and reported sale amounts help put today’s asking prices in context.
SourcesNYC ACRIS and Department of Finance rolling sales
Nominal transfers and records without a usable price are not ordinary market-price comps. Co-op coverage differs from condos.
The capital behind a property
Recorded mortgage documents add another layer to a property’s history, including later assignments, modifications and releases.
SourcesNYC ACRIS mortgage documents and cross references
A recorded mortgage amount is not a current loan balance. Co-op UCC financing is outside this feed.
The common foundation
City address records and property characteristics connect different descriptions of the same place.
SourcesNYC Property Address Directory, Geoclient and PLUTO
A tax lot, a physical building and an apartment are different entities. Unit identity matters when matching a sale.
The city’s valuation
Tax-roll records provide market and assessed values as a separate reference alongside listings and transactions.
SourcesNYC Department of Finance assessments and PLUTO
A city assessment follows tax rules; it is not an estimate of what an apartment would sell for today.
What deserves a closer look
Permits, violations and reported conditions give buyers and owners more context about a building’s history.
SourcesNYC DOB, HPD, 311 and health-related public datasets
Complaints are reports, not confirmed findings. Dates and status matter, and records may describe the whole building.
Who represents the listing
Listing contacts and brokerage attribution connect market activity to the people and firms representing properties.
SourcesRetained listing contacts, brokerage records and matched ACRIS records
Historical listing attribution does not guarantee a current affiliation. A matched outcome does not establish every party’s role in a transaction.
Around the address
Nearby businesses, development and transit activity add context beyond the property itself.
SourcesNYC and New York State public datasets, including DCP, parks and MTA
A new observation is not a confirmed opening. An application is not approval, and station entries are not street foot traffic.
Preserve document references, source dates and the meaning of each record. Filing dates, sale dates and observation dates can tell different stories.
Normalize addresses and connect them to NYC tax-lot and building identifiers. Use unit details where available; keep uncertain connections separate.
Bring related records into timelines, comparable sales and building summaries. Derived signals help interpret the evidence alongside the original facts.
Coverage is uneven. Not every property has every data type. Missing records do not mean no activity, and a building record does not always identify a specific apartment.
Sources move at different speeds. Listings, recorded documents and city releases follow different schedules. Public records can arrive late or be corrected later.
Facts and signals have different roles. A listing price, a recorded amount and a comparable-based value read are different measures. Connections and summaries should be read with that distinction in mind.
Start with a building, explore a neighborhood, or read the market.
