Question:
Can someone else - not the owner, go into a home that was sold for Pesach to water the plants? Is that then like trespassing?
Answer:
Hello,
It is permitted for him to go into the apartment to water the plants. The reason is that it is stipulated in the contract that the gentile allows entry into the sold area, the owner on an irregular basis.
Best wishes
