A narrower, more useful role

From scattered records to a review-ready file.

Overtaxed prepares the evidence trail. The professional verifies the facts, chooses the argument and decides what happens next.

Reconstruct

Bring assessment stages, parcel records, property characteristics and appeal history into one source-linked view.

Overtaxed: Assembles and flags
Professional: Verifies case context

Examine

Screen comparable candidates without hiding higher values, exclusions, conflicting features or ranking assumptions.

Overtaxed: Shows the alternatives
Professional: Selects the evidence

Prepare

Organize a draft case file around source references, review notes and questions that still require judgment.

Overtaxed: Structures the draft
Professional: Approves, files, represents

Inspectable by design

A trail to examine, not a score to trust.

Every consequential screen should remain visible: where a fact came from, what was excluded, which evidence cuts the other way and what the public record cannot answer.

Inspect the worked case

Source-linked

Trace values and characteristics back to the official public row.

Exclusions preserved

See which candidate left the set and the rule or property fact that removed it.

Adverse evidence retained

Higher assessments and conflicting facts stay in view instead of disappearing behind a favorable summary.

Uncertainty can stop the work

“Not enough evidence” remains an acceptable professional handoff.

One case, shown honestly

The historical reduction is real. Its cause is not public.

For 6913 W Summerdale, official records show a 17.08% Board of Review reduction. The reconstructed five-property set does not independently explain it. That conflict is the point of the sample.

Historical outcome is context—not evidence that this shortlist produced the result or that a similar case should receive a reduction.

The professional stays in control

Preparation is not judgment.

Overtaxed is a research-stage evidence-preparation workflow. It does not represent taxpayers, file appeals, provide legal advice or make automated reduction recommendations.

The case file is a draft for review. The firm controls client advice, evidence selection, requested value, filing and representation.
