Property and assessment record

The selected PIN, published characteristics, assessment values and source dates.

Uniformity analysis

A computed assessment-per-square-foot comparison with the peer basis and arithmetic shown.

Comparable exhibit

Available comparison properties to review and select in the builder; the records still need your judgment.

Printable evidence brief

Filing copy assembled from the records and your selections. Print it or save a PDF using your browser, and rebuild it from your account.

A two-minute preview

  1. 1. Find your property

    Search by address or PIN in the free checker. It shows the current peer comparison before checkout.

  2. 2. Check the evidence

    Review the area, class and source dates. An assessment gap alone does not establish overassessment.

  3. 3. Build and review

    For supported cases, purchase the brief, review the comparables and print. Verify your township’s current filing window and requirements.

Comparison group: R-1 homes built 1940–59 in assessor neighborhood 22111; 191 properties. This public comparison uses the dossier’s peer group. The paid builder’s case and selectable comparables should be reviewed separately.

Calculation: (78 ÷ 28.5 − 1) × 100 = 174% 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.

Inspect this property’s free check

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.
