Someone calling himself “Robert Williams” wrote the following in a comment, which I think deserves a reply:
When someone like Cal Skinner starts rambling about property taxes and assessments, I like to check his “facts” with my Township Assessor.
My Assessor gave me the Intnational Association of Assessing Officers (IAAO) standards for C.O.D.s, and they vary by property type and sample size.
For residential property with homes on it, a C.O.D. of 20% is only acceptable for “Rural or small jurisdictions / older properties / depressed market areas.”
So, apparently it IS on the spectrum.
There are whole different C.O.D. standards for income-producing property, vacant land, and so on.
There’s also something called the P.R.D (price related differential) that tells if you if cheap homes are overassessed and mansions are being underassessed.
So I guess that, again, Cal is an “expert” in something he knows little to nothing about.
First let me point out that Mr. “Williams” does not reveal the township in which he resides.
So, his source, his local assessor, remains anonymous.
In the late 1960’s I took and passed the International Association of Assessing Officers (IAAO) course that allowed me to be designated a “Certified Illinois Assessing Officer.”
While I was McHenry County Treasurer in the late 1960’s, I handled appeals for overassessed taxpayers that went all the way to the Illinois Property Tax Appeal Board.
All won their appeals.
To my delight, I was able to hand out a refund check for $500 to a Crystal Lake Coventry Subdivision resident.
The next year, the SPTAB required those handling appeals to be attorneys.
If you are satisfied with a margin of error of 20% where you live, that’s fine.
In my opinion, it is way too high.
At a 33 1/3% assessment level, A Coefficient of Dispersion of 20% means that half of the properties are assessed between 26.7% and 39.9%.
The rest are either assessed higher or lower.
In 1973, I passed the bill that required members of Boards of Review to pass a test for the first time. I then took the test and passed with a score of about 90%.
Spreading the farm assessment in effect for DuPage County to all counties was my bill.
I served on on the Conference Committee that lowered the assessment level to one-third of market value, making a concession to allow a three-year average that I very much regret.
I proved that the State Aid to Education formula was discriminating against overassessed counties like McHenry.
And I was McHenry County Treasurer for four years (1966-70).
If that doesn’t qualify me to “rambl[e] about property taxes and assessments,” I can’t imagine what would.
