Vacancy Cost Calculator for Multifamily Units

The cost of vacancy in multifamily housing is straightforward arithmetic. Divide the unit's monthly rent by thirty to get the daily rent, then multiply that daily figure by the number of days the unit sits offline and by the number of units offline at the same time. A $2,400 apartment loses about $80 in rent for every day it is not leased, so a twenty-one day turn across three units costs roughly $5,040 in rent that was never collected.

What the arithmetic leaves out is why the turn ran long. Most vacancy is not construction time, it is waiting time between trades: the painter arriving after the flooring crew finished a week earlier, the fixture install held for a punch item nobody logged. Cutting those gaps is what a coordinated turnaround buys. Use the tool below to model your own rent, unit count, and turn length, and see what a shorter, sequenced schedule would return.
