Effingham County parcel 13-09-007-021
Is the assessment on 4141 N 1300th St Mason IL 62443 fair?
Assessed at $95,850 as residential, Union 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
40.5%
of what it sold for (middle half 30.4–55%); the statute says 33.33%
This parcel among them

Their assessed values
$38,040
median; $22,830 to $168,980. This parcel: $95,850
Your assessment is higher than 4 of the 5 homes near you that sold in the last 3 years, in a neighbourhood already assessed at 40.5% 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.

Ask us to look at it properly
The table above is where an equity argument starts, not where it ends: a Board of Review wants an opinion of market value, and that means someone who has stood in the houses. We will look at 4141 N 1300th St Mason IL 62443 against what has sold and tell you honestly whether an appeal looks worth the trouble. No cost, no obligation.
