What constitutes necessary property that exempts an individual from the obligation of Hajj?

Primary text

Residency or the needs of one's dependents for a dwelling exempts an individual from Hajj. Likewise, property whose rent is necessary for the maintenance of the individual or his dependents is exempt. Furthermore, inventory (bida'ah) whose depletion would disrupt the profit needed for sustenance, or livestock requiring care (sa'imah), also exempt the individual from Hajj. If the individual possesses surplus property beyond these necessities, selling it for Hajj becomes obligatory.
