Suppose a Jew will be vacating an apartment or other property rented from a gentile. In such a case, he is permitted to take down his mezuzos before leaving. How long before actually moving out may he take down the mezuzos? Must it be during the last day of the lease, the last minute of the lease, or after the lease ends? Or may he pack up his mezuzos in the normal process of packing his things?
Hypothesis: Based on the laws of eiruvim, it seems to me that food plays a role in the halachic definition of "one's own" dwelling. Therefore, I would suppose that he may take down and pack his mezuzos as soon as he has removed all his food (or perhaps only his bread) from the property.
