How to add Units to your Comparable Properties

Use this tutorial when a comparable property has multiple non-ADU living units that need to be represented in the Sales Comparison Approach.

Before you begin

Before you begin, open the URAR report. Gather MLS sheets, public records, listing data, photos, or other support for each comparable. Confirm how many non-ADU units each comparable has.

Confirm whether any unit is an ADU. Keep regular units separate from ADUs. Confirm the subject unit structure first so the comparable grid has the right comparison context.

Open Sales Comparison Approach

Use the left navigation to open Sales Comparison Approach. Locate the comparable property you need to edit. Confirm the comparable address is correct.

Confirm the comparable sale data is entered before adding detailed unit rows.

Open the comparable structure menu

Find the comparable column or comparable card. Open the add/options menu for that comparable. Choose the unit-related add option.

If unit options are grouped by dwelling or structure, select the correct structure. Add only the units that belong to that comparable.

Add the comparable unit

Add the unit row. Identify the unit clearly if the field is available. Complete unit-specific room count fields.

Complete living area fields. Complete quality and condition fields. Complete any location, basement, finished area, or utility fields that apply.

Repeat for each non-ADU unit in the comparable.

Compare against the subject

Confirm each comparable unit is aligned with the correct subject unit or subject row. Review differences between the subject and comparable. Enter adjustments where supported.

Add commentary when the unit difference affects comparability. Remove any duplicate unit rows.

Validate

Run validation. Review unit-related errors and warnings. Correct missing unit details.

Confirm regular units are not marked as ADUs. Save the Sales Comparison Approach section. Re-run validation until the unit rows are clean.
