Result in Legal Challenges, a “Flood” of Appeals...

“...Officials across the country say there is no question that the number of [assessment] appeals has risen from the usual trickle to a flood.” (NYT, July 4, 2009)

And Serious Community Development Implications

Greatest challenges in neighborhoods that are most affected by foreclosure crisis

Risk of over-assessments for homeowners who can least afford them

The Cook County Assessor’s Office (CCAO) Took Action

Project Goal: Enhancing the Assessment Process to Better Estimate Property Values in the Current Environment– How to account for the recent downturn in

the market after years of steady growth?– How to account for the increased

influence of foreclosures?

Project Structure

Build from Existing ModelsOperate within current systems

(data, software and staffing)Deliver under tight timeline

dictated by assessment process

Accuracy– How close are assessed values to actual market values?

Uniformity– Are similar homes assessed at similar values?

Equity– Are different value homes assessed at the same rate?

Practical Considerations– Ease of implementation, transparency

Criteria for Success

Process and Diagnostics

Evaluation of current model Introduce modifications, from simple to

complex Evaluate each step using rigorous

statistical techniques Review outcomes

Develop recommendations

Evaluation via Out of Sample Testing

Enables readily determining quality of current systems and modifications

Detailed Reports Generated for Each Model Modification

To preserve confidentiality, the following graphs and figures were constructed for

illustrative purposes only, and do not reflect specific project data or results.

DISCLAIMER

Number of foreclosure filings in the neighborhood within the past year

Presence of foreclosure filings on the same block within the past year (dummy)

Also tested: Block-level number instead of dummy, REO instead of filing, different distances (1/32 mile, 1/16 mile, 1/8 mile)

Tested Multiple Foreclosure Measures

Accounting for the Impact of Foreclosures

Created new variables that capture and account for nearby foreclosures

New variables better assess the value of the foreclosed property as

well as non-foreclosed properties on the same block

What Does This Mean for the Assessment of Individual Properties?

No Filing Nearby Filing Nearby

Accounting for the Downturn in Housing Trends

Created new variables that track the housing market on a more “real time”

basis

New variables adjust to market trends – regardless of whether they are up,

down or flat

Project Impact

Savings for lower income homeowners (holding aggregate tax revenue constant) in the order of

sixty million dollarssixty million dollars. The changes have been incorporated into the

current round of assessments and will be applied to all future assessments.

Additional assessment model improvements have been identified and are being explored

together.

The “New Frontier” of Property Assessments

Opportunity to apply newest statistical and data mining techniques to

assessment models

Potential to deliver assessments more accurately, equitably and efficiently,

leading to a new generation of property assessment practices

In Sum...

Time to revisit “one of the most important, easily documented, and manipulable of all influences upon the social geography of

cities, and also one of the most neglected.” (Harris and Lehman, 2001)

A modest investment generates a large financial impact for neighborhoods and

homeowners who sorely need help. The approach, techniques and solutions of

the project are easily transferable to other counties.
