A guide to the inventory

Explore with context

This is a parcel inventory, including homes that may or may not be for sale. One row means one tax parcel or assessment identifier, which may contain several buildings or units.

Choose an area, then explore

The filters above the map apply to both map and inventory. All property classes are included, including multifamily. Search owners, buyers, sellers, attorneys, addresses, parcel identifiers and place names; combine keywords in any order. Inventory searches include all recorded transfers for a property. Transfer views search the property and each individual transfer. For each size, choose ≥ (at least) or < (less than), then enter a number. Blank sizes apply no limit. Unknown sizes remain included by default, with an explicit count when size filters are active.

Pan and zoom to a neighborhood, then choose Use map view as area, or use Draw area and click two opposite corners. The boundary filters parcel representative points, not polygon intersections. Panning after choosing an area does not change it. Clear area removes only the geographic filter.

Active filters above the table show the shared rules from the top controls and map area, followed by additional table filters. Use the filter buttons to return to their controls; × clears a rule. Shared rules apply first; additional table filters narrow those results and also apply to the map. Include unknown sizes applies to the shared size rules.

Table settings can also choose columns, sort or chart the data. Grouped tables and charts show summaries; the map continues showing the underlying matching parcels. Selecting a row or map location preserves map position. Use Center on map for intentional navigation. Overlapping points offer a property chooser. Click again, Close or Escape to clear selection.

Unknown coordinates remain in the table except when an area is selected. Map tiles require a connection to OpenStreetMap; the table works without tiles. © OpenStreetMap contributors.

Research transactions

Candidate market sales shows every matched arms-length, single, whole-parcel transfer with a positive, nonnominal price in the chosen period. Source flags screen candidates; they do not verify comparable quality. All recorded transfers retains nominal, nonmarket and uncertain records. Inventory date filters use the latest recorded transfer; sales date filters use each transaction date.

The detail card shows every normalized property field and every original county attribute, including recorded owners, mailing information, utilities and source dates. Transfers include every matched source field: buyers, sellers, attorneys, deed references, conditions and blanks, including earlier sales hidden by a later nominal transfer. Price per square foot is shown only for qualifying whole-parcel candidates with valid living area; physical attributes describe the parcel source snapshot, not its historical state at sale.

Understand coverage and limitations

The data-quality report explains known gaps, their effect on comparisons and what remains unresolved. It includes the current dataset's missing-field counts and reviewed source evidence.

Save and share a view

Copy link shares meaningful changes to filters, the chosen area and table settings. Unchanged defaults are omitted, so the default view has a bare URL. The URL preserves your view; map position is remembered only in this browser. Opening a shared area frames that area. Reset view restores the full inventory across both villages and all property classes. Shared links do not freeze the dataset: results change after a data rebuild. Everyone with access can download the complete dataset; filters are not access controls.
