ANSWER:

There is nothing prescribed for this. Simply make dua to Allah and after that, appoint someone to look after the house in their absence. One of the Athkar of the morning and evening include asking Allah for protection in our religion, life, family and wealth. This covers the property as well. 

 

Sheikh, is there any dua to protect property in our absence? As we are trying to get our parents to stay with us in a different country but they worry about their home.
