Underwriting notes

  • Utility bill-backs (RUBS): add an Additional Income row, since tenant reimbursements are hidden for Multifamily.
  • Loss-to-lease: use a Pro Forma rent roll with market rent in the Pro Forma column, so buyers see in-place and market rent side by side.
  • Concessions: enter in-place rent net of free rent, and describe the concession in the unit Notes.

Complete the Multifamily workflow

Multifamily steps

  1. 1

    Select Multifamily

    Create New, Select Property Type

    Choose Multifamily.

    Expected result: Unit-oriented labels and metrics are active.

    If this step does not work

    Change the property type in Property Details if labels are not unit-based.

  2. 2

    Complete property totals

    Property Details

    Enter the property unit count and asking price.

    Expected result: Price/Unit has the required denominator.

    If this step does not work

    Correct the unit count before entering a grouped rent roll.

  3. 3

    Choose individual or grouped input

    Rent Roll Type

    Use Unit-by-Unit for distinct unit records or Unit Mix for repeated floor plans.

    Expected result: The table matches the source schedule.

    If this step does not work

    If the source only has category averages, use Unit Mix.

  4. 4

    Enter occupied and vacant inventory

    Rent Roll

    Add all categories or units with counts, average SF, and monthly or annual rent.

    Expected result: Occupied plus vacant inventory reconciles to total units.

    If this step does not work

    Correct counts and remove overlapping categories.

    Review the populated multifamily example and verify the units, property facts, and applicable model before preparing your own document.
  5. 5

    Complete income and expenses

    Income & Expenses

    Add ancillary income and operating expenses in the displayed model columns.

    Expected result: Multifamily EGI and NOI reconcile.

    If this step does not work

    Do not add tenant reimbursements because this property configuration hides them.

  6. 6

    Review final metrics

    Review & Customize

    Verify unit count, occupancy, Price/Unit, Price/SF, unit table, and financial pages.

    Expected result: The final presentation matches your underwriting.

    If this step does not work

    Return to Property Details or Rent Roll for a denominator or inventory mismatch.

Resolve Multifamily mismatches

Rent is multiplied too many times

Likely cause: A Unit Mix rent was entered as the category total instead of per unit.

  1. Enter rent per unit.
  2. Confirm Number of Units.
  3. Recheck annual row total.
Occupancy differs from area occupancy

Likely cause: Multifamily uses occupied unit count, not occupied SF.

  1. Reconcile occupied and total units.
  2. Use SF only as a separate physical metric.
  • Total units match the property
  • Inventory count reconciles
  • Per-unit rent basis correct
  • Vacancy included
  • Price/Unit and Price/SF checked
  • Tenant Profiles absent as expected
