Break-Even Occupancy

Break-even occupancy is the minimum occupancy rate at which a property's income exactly covers its operating expenses and debt service, with no cushion left over. It's used by lenders to stress-test how much vacancy a property can absorb before it can no longer service its loan, and is typically expressed as a percentage of gross potential rent.

Formula: Break-Even Occupancy = (Operating Expenses + Annual Debt Service) ÷ Gross Potential Rental Income × 100

Example

A property with $300,000 in combined operating expenses and debt service against $400,000 in gross potential rent has a break-even occupancy of 75%, meaning occupancy can fall to 75% before the property stops covering its costs.

Break-even occupancy gives lenders and investors a more intuitive risk gauge than DSCR alone, translating loan risk into a concrete, easy-to-grasp number: how far can occupancy fall before this deal is underwater? A property with an 85% break-even occupancy has far less cushion than one with a 65% break-even occupancy, even if both currently show the same DSCR at full occupancy.

Lenders compare a property's projected break-even occupancy against realistic vacancy scenarios for the submarket and property type — a multifamily property in a stable market with historical vacancy around 5–8% has ample room below a 75% break-even threshold, while a single-tenant office property with a break-even occupancy near 90% has very little room for error if that tenant doesn't renew.

Break-even occupancy is especially important for single-tenant or highly concentrated properties, where a single lease event (non-renewal, default, or early termination) can swing actual occupancy dramatically rather than gradually, making the cushion below break-even the key measure of resilience.
