Unity of Operation

(15-23-101, MCA and ARM 42.22.102)

We value Centrally Assessed property using the Unit method and may include a:

• Cost indicator
• Capitalized income indicator
• Market indicator

We use an industry capitalization rate to estimate values when relying on the capitalized income indicator.

We perform an annual capitalization rate study for each industry to set the capitalization rates.

You can learn more about the study on our Capitalization Rate Studies page. (ARM 42.22.111)
