I live in my triplex full time. The other two units are rented. One had vacancy of 4 months. What do I say for days rented?

Units 489, 491, and 493 are all part of a single property triplex I own.  I live in unit 491 full time all year.  Unit 489 had 4 months vacancy.  Unit 493 was rented full time all year.  What do I say for days rented for this property?
