Property research feeds

Use filtered property records to support a local investigation. Inspect the criteria, dates and assumptions before drawing conclusions; these feeds do not establish misconduct or a project’s effects.

Assessment comparisons

Residential properties built before 2022, with more than 400 building sq ft, assessed more than 10% above a peer median and no recorded appeal from 2024 onward. Peers share an assessor neighborhood, zoning class and 20-year construction era, with at least eight properties in the group.

Ranked by assessed value at stake

Permit coverage gaps

Pre-1985 residential properties with no matching building permit in the available county feed (coverage varies by town and date) — candidates for reviewing possible maintenance needs. Missing county permits do not establish that systems were never replaced.

Oldest, highest-value homes first

Building-system estimates

Building-system age, due/overdue status and clock scores for roof, HVAC and water heater, alongside the parcel research score. These model estimates do not establish a system’s condition.

Raw model output · most overdue first

Permits and assessment changes

Properties with more than $50,000 in declared permit value and an assessment change of 5% or less. Review the work and assessment history; this does not establish unassessed value or investment upside.

Declared permit value vs assessment change

Recorded ownership holdings

Recorded owners linked to two or more parcels in the selected town, with assessed totals and their latest recorded deed.

Largest holders first

Street activity

Streets with at least 10 parcels, comparing turnover, median assessments and permit activity since September 1, 2024 through the active release.

Recorded turnover since September 2024
