Evidence supported an appeal
Comparable sales in the property’s assessment neighborhood clustered below its implied value. A nearby sale provided the clearest starting point for a filing grid.

What we review
An increase alone
isn’t the whole story.
We look at six common evidence paths, starting with the simplest factual checks. The right path depends on your property and the records available.
See what a verdict can tell you01Factual record error
The public record lists a feature incorrectly, such as living area, basement finish, bath count, or garage.
02Recent purchase
A recent arm’s-length purchase may provide direct evidence that the assessment is above the market transaction.
03Recent licensed appraisal
A properly dated licensed appraisal may be useful evidence. We identify when it may be worth discussing with an appraiser.
04Recent comparable sales
Comparable neighborhood sales may show that similar homes transferred below the value implied by the assessment.
05Assessment equity
Assessment records for similar homes may show a meaningful lack of uniformity within the same local market.
06A legal issue
Prior decisions or other legal grounds can require an attorney. We flag those situations instead of trying to handle them.
An honest recommendation
Sometimes the best move
is to leave it alone.
We’ll tell you when the evidence supports an appeal, when it doesn’t, and when you may need professional help.
Evidence supported leaving it alone
A closely comparable nearby home had sold well above the assessed value. Filing could have invited scrutiny of an already favorable assessment.
Several issues warranted review
The public record and prior appeal history did not align cleanly. The analysis documented the conflicts and identified where professional advice could be appropriate.
Anonymized examples, not promised outcomes. Any savings discussed in an analysis are estimates, not results.

Frequently asked questions
A little more clarity.
What to know before you send your notice.
Is this legal advice or a law firm?
No. Blue Notice provides property research, public-record analysis, and educational material. We do not give legal advice, represent homeowners, sign filings, or appear at hearings. When a situation calls for legal judgment or representation, we will point you toward an attorney.
Is the analysis an appraisal?
No. We do not produce an appraisal or an opinion of value. We organize public sales and assessment records and explain what those records may support. A licensed appraiser is a separate professional, and some cases may benefit from one.
What if the evidence does not support an appeal?
We say so. The free verdict is designed to be useful even when the answer is not to proceed. You receive the reasoning behind that conclusion and remain free to make your own filing decision.
How fast is the verdict?
We aim to return the free verdict by 5 p.m. Chicago time on the second following business day, excluding observed US federal holidays. This is a service target, not an extension of your county deadline. We only accept standard intake when at least three business days remain.
Can you guarantee a reduction?
No. The Lake County Board of Review controls every outcome. Historical success estimates can be useful context, but outcomes vary by facts, evidence, and decision-maker. We make no promise of a reduction or savings.
