3. MC COST HISTORY
2013 Conversion From DOR Cost to “AZ (Arizona) MVP SEG”
AZ MVP SEG = Marshall Valuation Segregated Cost With Added Arizona Components
Problem:
Segregated Cost Was Complex; Difficult to Teach and Learn
Solution:
MC Created Templates for AZ MVP SEG to ID Base Cost Components, Limit Component Adjustments and Add-Ons.
Result:
AZ MVP SEG With Templates Is MC’s Attempt To Simulate M&S Commercial Engine (Square Foot Method)

4. The Segregated method Vision System Cost Conversion
Unbundle AZ MVP SEG Base Component Templates
Using AZ MVP SEG In Vision:
No More Templates
Will Be A True Segregated Cost System
Every Property Component Identified And Listed Per Brown M&S Book

5. THE SEGREGATED METHOD PROS Detailed Component Information
Property Specific
More Adjustments Possible For Unique Property Attributes
The specific components create a more detailed account of what the property has in terms of the improvement.

6. THE SEGREGATED METHOD CONS Complex
DOR Discussion About Segregated Cost (2003):
Marshall & Swift designed it primarily for use on large, complex buildings that require a great deal of component detail for an accurate cost value. Because of this, the system is more sophisticated than needed for most residential and commercial structures.
This has resulted in a steep learning curve for new appraisers and extended time at the property to gather data and fill out listing forms.
Back at the office, this means more work and more chance for input error by data entry personnel.

9. THE SQUARE FOOT METHOD PROS CONS
Easier for staff to understand relationship between select components/add-ons and value
Less time in field identifying components
Fewer errors in component data entry
CONS
Cannot account for property peculiarities or uniqueness because the system develops cost for typical construction
The square foot method is more general due to less detail listed on the cost approach

10. TIMELINE

11. conclusions
This was a significant decision that effects the future of the office.
This decision will keep the office moving in the same direction as the assessment authorities across the country.
We will be adjusting our training to accommodate the new direction.
A review of the existing segregated has begun to verify which segregated components are part of the square foot method and which components are required to be adds to the occupancies.
