Effingham County parcel 02-20-008-049
Is the assessment on 411 Old Mill Rd Dieterich IL 62424 fair?
Assessed at $90,600 as residential, Bishop 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
21.1%
of what it sold for (middle half 18.6–25.3%); the statute says 33.33%
This parcel among them
7 of 7

Their assessed values
$30,610
median; $11,550 to $61,250. This parcel: $90,600
Your assessment is higher than 7 of the 7 homes near you that sold in the last 3 years. The neighbourhood is assessed at 21.1% of what it sells for, under the statutory third, so sitting above the neighbours is not by itself over-assessment; what matters is whether those homes are like yours.
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.
