Effingham County parcel 09-17-011-061
Is the assessment on 23 N Main St Altamont IL 62411 fair?
Assessed at $50,000 as commercial, Mound 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
28.1%
of what it sold for (middle half 23.9–38.3%); the statute says 33.33%
This parcel among them
62 of 74
sold homes within half a mile are assessed below it
Their assessed values
$32,470
median; $8,530 to $88,650. This parcel: $50,000
Your own sale is the strongest evidence there is: at 33.3% of what you paid, this parcel is assessed well above the 28.1% the neighbours who sold are. That is worth asking about.
This parcel's own recorded sale: $150,000 in Dec 2023; the current assessment is 33.3% of that. A recent arm's-length sale of the property itself is the evidence a Board of Review weighs most.
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.

We will look at 23 N Main St Altamont IL 62411 against what has sold and tell you honestly whether an appeal looks worth the trouble. No cost, no obligation.
