Is the assessment on 415 N Seymour St Sullivan, IL 61951 fair?
Assessed at $55,492 as residential, SULLIVAN Township. Below: how the homes near it that actually sold are assessed against what they sold for, and where this one sits among them. Two facts from the county's own record — not an opinion of value, which is what an appeal ultimately needs and what we will give you if you ask.
How the neighbourhood is assessed
32.6%
of what it sold for (middle half 25.3–39.5%); the statute says 33.33%
This parcel among them
53 of 65
sold homes within half a mile are assessed below it
Their assessed values
$38,267
median; $10,251 to $210,785. This parcel: $55,492
Your assessment is higher than 53 of the 65 homes near you that sold in the last 3 years, in a neighbourhood already assessed at 32.6% of what it sells for. Not proof of anything — those homes may simply be smaller — but worth asking about.
The homes that sold near it
Arm's-length sales recorded with the county in the last 3 years, nearest first, with the assessed value the county carries for each today. Whether any of them is like this house — size, age, condition — is the question the record cannot answer and an appeal turns on.

Prices from PTAX-203 transfer declarations; assessed values from the county assessor's current file (so a home reassessed after its sale shows today's figure against yesterday's price). Not MLS figures. Nothing here names an owner.
How an appeal actually works here
- Talk to the assessor first. Many differences are a record error — a garage that came down, a square footage that was never right — and get fixed with a phone call, no appeal needed.
- The county Board of Review. A written complaint in the window after the township's assessments are published each year; the office can tell you the dates for this township. Evidence: a recent appraisal, comparable sales, or comparable assessments (the equity argument — the table above is where that starts).
- Then the state. A Board of Review decision can go to the Illinois Property Tax Appeal Board within 30 days of the decision — its forms and rules are on ptab.illinois.gov.
