English to Czech Bus/Financial Real Estate

"Voids" je nadpisem urcite sekce na webovych strankach, zde dodavam cely kontext:

Voids
Between tenancies, prior to tenancies and after the end of a tenancy, the security, maintenance and all charges relating to the property are the landlord's responsibility.
Utilities
We will ensure that all available utilities are connected to the property including one telephone line, electricity, gas and water. Check that all LPG bottle gas and oil tanks are full at the start of the tenancy and septic tanks empty.

Jde mi pouze o preklad vyrazu "Voids", myslela jsem, ze by to mohly byt "Prostoje", protoze v odstavci se mluvi o v podstate o prostojich mezi jednotlivymi najmy, ale nevim, zda je to spravny vyraz v oblasti trhu s realitami.
