Comps, According to the StL County Assessor’s Office


Below is a portion of an actual reassessment notice that was sent out in 2017.  As stated previously, these were the actual comps that were used to calculate the appraised value of the associated properties:


Even without knowing any specific information about the individual properties, you don’t have to look at this long to notice the wide range of sale prices --- from $399,000 to $910,212.  That’s a very wide range!  So wide, in fact, that it would have immediately indicated to anyone that was looking for comparable properties that these are obviously not “comparable.”  They’re not even comparable to each other so they can’t possibly be comparable to a subject property, regardless of the specifics of the subject property.

It gets worse when you look at the specifics of the comp’s properties:
  •         Johnson Place is a 2635 sq ft 4 bedroom 2-story built in 1992 on .23 acres
  •         Mason Meadows is a 2480 sq ft 3-bedroom RANCH built in 1988 on .45 acres located 1.41 miles away from the subject properties
  •          Loehr Estates is a 2557 sq ft 1-bedroom RANCH built in 2016 on .67 acres
  •          Clarjon is a 3201 sq ft 4 bedroom 2-story built in 1998 on .28 acres
  •          Des Peres Woods is a 2772 sq ft 4 bedroom 2-story built in 1987 on .35 acres located 1.58 miles away from the subject properties

This list of comps was used for more than a dozen different homes – none of which were ranches, and none of which were newer than 23 years old – yet this list contains two ranches, one of which was built in 2016 and only a year old at the time, and two comps outside of a one-mile radius.

For the associated target properties, there were 235 valid home sales in 2014, 15, and 16 within a one-mile radius of the target properties from which the County Assessor’s office could have chosen comps.  The County Assessor’s office was aware of the list of relevant home sales because they posted the list online along with the property reassessment information.  Yet in spite of having a very large list of homes available to them from which to choose, the County Assessor’s office opted instead to comp two of the five houses from outside of the one-mile radius.

Wait, what?

Remember 2005 Missouri Revised Statutes %137.115?



Except there were similar properties within one mile of the assessed properties.


In fact, there were dozens of very comparable homes sold, and numerous properties that were more similar and more closely located than the ones that were selected by the County Assessor’s office even from within the one-mile radius.

So why would the County Assessor’s office choose these poor comps when they had good ones available?

If the intention of the County Assessor’s office had been to accurately appraise the home values, then they would have simply chosen homes from the extensive available list that were actually comparable to the subject properties, as defined by the Statute above.  But if the intention of the County Assessor’s office was to increase the current assessed value, and the prior re-assessment had already resulted in an over-assessment, then it would be impossible to increase the assessed value further by using true comparable home sales.  They simply wouldn’t mathematically support an increase in assessed value and might even result in a decrease.  The only option then would be to select homes in which the sale price would support an increased assessment, regardless of their comparability.  And that’s exactly what they did.

I don’t know which action is more reprehensible – the fact that the County Assessor’s office manipulated the selection of comps badly in order to artificially inflate the property values, or the fact that they so blatantly disregarded Missouri Statutes in the process of doing so.

This was just an example.  The number of property records that I encountered in which the County Assessor’s office similarly manipulated the selection of comps is significant, and I really only looked at properties that were within a mile of mine.  Plus, they have been doing so for at least a decade that I can prove, sometimes even selecting “comps” that are more than 5 miles away.

But wait, there’s more…!

When comparing even legitimate comparable properties, it’s virtually impossible to find two that are identical.  Therefore, the County Assessor’s office will make adjustments to the sale prices to account for differences in the property descriptions.  The process is legitimate; the manner in which the County Assessor’s office applies it is not.

In this example, the County Assessor’s office chose a comp (the ranch on Mason Meadows) that was already significantly higher-priced due to its location in Town and Country.  Then, the County Assessor adjusted the sale price even higher still, because it was smaller and older than the target properties.

And yet there’s still more….

Remember the discussion about the Computer-Assisted Mass Appraisal system (CAMA) from Tyler Technologies that the County Assessor’s office uses? 

The comps selected and calculations performed in this example were done using the CAMA.  The Missouri Statute even makes reference to the assumption that assessments are made by a computer unless proven otherwise:



Think about what this means for a second. 

These aren’t “human errors.”  This wasn’t done by some newbie trainee, or by someone having a bad day, or by someone simply bad at their job. 

This was done by a computer. 

Computers don’t make mistakes.  They don’t get creative.  They don’t go off-road and do their own thing. 

Computers do exactly what they are told to do. 

Which means, this blatant and recurring inappropriate selection of comps is by design.  And the instruction to do so is embedded either in the computer code itself or in the control tables that support the code.

I’m a firm believer in the adage, “People that have nothing to hide, hide nothing.” 

No wonder the County Assessor’s office doesn’t want to answer anything about how they come up with their numbers…….
