Public assessment comparison

660 Prospect Ave

PIN 05-17-417-019-0000 · tax year 2026

Published assessed value: $796,376
Building area: 7,798 sq ft
Subject assessment / sq ft: $102
Peer median / sq ft: $50
Versus the peer median: +104.9%

Comparison group: R-1 homes built 1880–99 in assessor neighborhood 23022; 51 properties. This public comparison uses the dossier’s peer group. The paid builder’s case and selectable comparables should be reviewed separately.

Calculation: (102.1 ÷ 49.8 − 1) × 100 = 104.9% versus the peer median. Displayed values are rounded; the calculation uses full precision.

What this means: the records place this parcel above its peer assessment median. Property condition, omitted characteristics and newer records can change the interpretation.

Brief availability: the current product screen offers a uniformity brief for this sample. This is product eligibility, not a legal determination or a filing deadline.

Before paying

The checker can withhold the brief when comparable evidence is insufficient, assessments are near or below peers, or a recent appeal is recorded. Missing or delayed records can affect that decision. An existing plan with appeal access already includes the builder.

Your purchase unlocks this PIN’s builder; it does not buy representation or submit anything to the county. Review the methodology, purchase terms and refund policy. No assessment reduction is guaranteed.
