Occupancy rate

Occupancy rate is the complement of vacancy: the share of available capacity that is occupied, so 95% occupancy and 5% vacancy describe one fact from two sides. Every underwriting number on this site is built from the vacancy side.

Occupancy rate = 100 − vacancy rate

Worked example

The standard deal runs at 95% occupancy, which costs $1,635 of its $32,700 potential; cash flow reaches zero near 82% occupancy, which shows the example's remaining buffer.

Every example in this glossary uses the same deal: a $265,000 duplex renting for $2,650 a month, bought with 25% down at 6.75% over 30 years, producing $19,310 of net operating income.

The mistake to avoid

Underwriting 100% occupancy because the unit is full today. Every tenant eventually leaves, and the turn — the empty days between leases — belongs in the model whether or not this year's calendar shows it.

Where this is calculated

The vacancy rate calculator computes this from your own numbers and shows the arithmetic expanded. Empty days and vacant unit-months turned into the rent they cost, then fed back through your own deal as real NOI and cash-flow differences against your underwriting allowance.
