Mass Calculation

Navigate: Closed Valuation > Mass Calculation

Description

Use this task to:

  • Run calculations as unattended batches. This allows you to process a large numbers of records unattended, overnight and during weekends.

  • Run ‘what-if’ scenarios by determining whether changes should be committed to the database or not. You can test various configuration settings to determine which is model is most appropriate before actually running it.

  • Select appraisal sites for recalculation, using a variety of selection criteria and determining whether the recalculation is general (e.g. an entire market area), or specific (e.g. certain properties within a neighborhood).

  • Choose from a variety of valuation models.

  • Specify what type of reports will be generated during the mass calculation exercise.

Steps

  1. On the Recalculate Appraisal screen (Step 1), specify a search option and make a selection from its drop-down list, which identifies PINs and records to be included in the recalculation process. Available options represent a hierarchical structure for grouping properties within a jurisdiction (for example, a county).

    • By Market Area – Select a Market Area

    • By Sub Market Area – Select a Sub Market Area

    • Neighborhood – Select a neighborhood

    • By TAG – Select a Tax Authority Group

    • By PIN List – Select a list of PINs (Property IDs) in order to create a PIN List

    • Other Criteria – Defining Constraints allows to conditionally limit the appraisal sites incorporated in the mass calculation process. Use the Constraints panel to add criteria. This panel is disabled unless the Other Criteria radio button is selected.

      1. Click Add New in the panel's title bar.
      2. Make a selection from the Entity, Attribute, Operator and Value drop-down lists.

        • Start with Entity and work across the panel. Available selections in the drop-down lists will update according to selections.

        • Entity – An appraisal site or component of an appraisal site for example, building, feature, etc.).

        • Attribute – An attribute/property related to the selected Entity.

        • Operator – Available operators populate based on your Attribute selection. If the In operator is selected use the ellipsis button (…) to open the Systypes Selection dialog box to select a list of values using an appropriate check box.

        • Value – Available Values populate based on your Attribute selection. You can partially type a word/value to see a list of matching values; wildcards cannot be used.

      3. Continue adding constraints as needed.
        • To delete a constraint click the red X at the end of the row.

  2. Click Next.

  3. In Step 2, enter or select the effective date for the mass calculation.
  4. In the Select Algorithms for Recalculation panel, select the checkbox for one or more items in the grid and click Next.

  5. In Step 3, enter the batch name.

  6. Under Calculation Options:

    • Select Report Only to run the recalculation in verify mode (optional). No PINs are updated but the generated reports display expected results allowing you to fine tune your calculations before running them against properties in the database.

    • Select Remove Comparable Overrides and Include in Calculation to remove any overrides set for a Comparable Sales report on individual PINs before running calculations.

  7. Under Select Options for Parcel Level Reporting, select one or more options. These options include functionality under development that may not yet be available.

    • Write a warning if Ending value is more than [ ] lower than initial value – sets a warning bracket if the new value (recalculation) is lower than the ending amount.

    • Write a warning if Ending value is more than [ ] higher than initial value – sets a warning bracket if the new value (recalculation) is greater than the ending amount.

    • Ignore New Construction Changes – ignores changes due to construction in cases where this may have affected the ending value.

    • Ignore Demolition Changes – ignores changes due to demolition in cases where this may have affected the ending value.

    • Create Value Differential Report – shows prior value and current value if there has been a change.

    • Create Value Change By Property Type – shows value change sorted by property type (e.g. single story to multistory).

    • Create Value Change By Change Reason Report – shows value change sorted by change reason (e.g. new construction, demolition).

  8. Make a selection from the Set Primary Value Method To drop-down list, which allows you to assign a primary valuation method to PINs that are included in the mass value calculation.

    9. NOTE: If the selected Primary Value Method is associated with a neighborhood, Aumentum recalculates the subject's value and sets the selected value method as the primary valuation method for the property. If the selected Primary Value Method is not associated with a neighborhood, Aumentum does not recalculate the subject's value and displays an error message in the Mass Calculation batch report. You may also view and recover overridden buildings, features and land values established in Case Management.

  9. In the Scheduling Options panel, set your desired dates and times for the batch report. If no Scheduling Options are set, the batch will be run immediately.

  10. Click Finish to queue and process the batch. The Monitor Batch Processes screen opens automatically.

    • Click Refresh until the status shows Completed, then click on the item to open the View Batch Process Details screen.
    • You can open the report by clicking the link in the Report panel.

  11. Click Close to end the task.

NOTE: Mass Calculation does not change the value adjustments on the Appraisal Site and Comparables tab on the RPA main page screen; Comp Report Overrides persist unless Remove Comparable Overrides and Include in Calculation is selected in Calculation Options.

Tips

Navigate to the PIN to verify that it was recalculated.
