What is a rent roll?
A rent roll is a detailed schedule of all rental income from a property. For multifamily buildings, it lists every unit with lease terms, current rent, move-in dates, and tenant information. Investors and analysts use rent rolls to verify income, calculate occupancy, and model cash flows during underwriting. It's one of the most critical documents in any multifamily acquisition.

The template supports any number of units. Simply add more rows as needed. The summary formulas auto-update to include all data rows.
Can I customize the columns?
Yes. The template is fully editable. Add, remove, or rename columns to match your underwriting workflow. Just update the summary formulas accordingly.
Is it really free?
Yes, completely free. We built this to help CRE professionals. If you want to automate data entry entirely, check out Primer.
How do you calculate loss to lease?
Loss to lease is the difference between market rent and actual in-place rent across all units. Calculate it as: (Market Rent - In-Place Rent) × 12 for the annual figure. For example, if market rent is $1,500/unit but tenants pay $1,400/unit across 100 units, annual loss to lease is $120,000. This metric reveals upside potential in a rent roll.
What is economic vs. physical occupancy?
Physical occupancy measures the percentage of units occupied. Economic occupancy measures the percentage of gross potential rent actually collected — accounting for vacancies, concessions, bad debt, and loss to lease. Economic occupancy is always lower and gives a more accurate picture of revenue performance.
What is the difference between a rent roll and a unit mix?
A unit mix is a summary of unit types and counts (e.g., 20 one-bedrooms, 15 two-bedrooms) with average rents by type. A rent roll is unit-level detail showing every individual unit's lease terms, tenant, and rent. The unit mix is derived from the rent roll. Both are needed for underwriting, but the rent roll provides the granular data for cash flow modeling. Sources: NMHC, NAA.
