What Censum checks

01 Assessment spike

Detects assessment increases significantly above the township median.

02 Market divergence

Compares assessment growth to actual market sale-price trajectory in the surrounding area.

03 Permit reconciliation

Cross-references assessment increases with public building permit records.

04 Township ratio study

Measures inequity in assessment-to-sale-ratio across the township.

05 Prior BOR history

Weights the property's historical pattern of successful or denied appeals.

06 Comparable sales

Surfaces similar nearby sales assessed at materially lower ratios.

07 Equity (sister parcels)

Compares against assessor-defined sister parcels for uniformity violations.

08 Neighborhood appeal success

Encodes the success rate of recent BOR appeals within a 0.25-mile radius.

09 Dollar impact

Filters for cases where the dollar magnitude of expected savings justifies effort.

How result bands are assigned

Customer path Meaning Odds band Price
Strong yes Highest-confidence standard appeal package 90%+ $99
Strong case Meaningfully stronger appeal signal 70-90% $99
Worth checking Clears the review floor 50-70% $99

The conviction score is a secondary explanatory score used to show why a case was flagged. It does not override the modeled win-probability band after eligibility, data-quality, and suppression checks.

Source discipline

Official records first.

The methodology is built around public assessment records, public sales records, permit context, comparable-property analysis, and historical appeal outcomes.

Censum does not present the score as a county decision. It presents a structured evidence read so homeowners can decide whether the filing effort makes sense.

Built on hard data

Our analytics combine public assessment, sales, and appeal records with proprietary signal weighting and a calibrated machine learning layer trained on years of historical Board of Review outcomes.

Scoring starts with public assessment, sales, permit, appeal, and county-process records. Censum does not buy personal profiles from data brokers for the scoring layer. If you buy a packet, upload evidence, join alerts, or contact support, Censum collects the workflow information described in the Privacy Policy.

The specific blend of signals, weightings, training methodology, and refresh cadence is proprietary to Censum.

Proof standard

Built for review, not hype.

Censum keeps public claims tied to live product behavior, public data sources, and sample packet evidence.

What we show
  • Modeled tier and recommended pricing path
  • Comparable properties and assessment history
  • Top drivers behind the packet recommendation
What we do not promise
  • No guaranteed reductions or refunds
  • No county or government affiliation
  • No legal or tax advice

Censum is an independent property-tax analytics service. Public sample pages are illustrative and privacy-safe. Actual packet contents depend on property type, township, available public records, appeal window, and model eligibility checks.
