But most recommended getting in touch with the doorman or managing agent, to risk offending family members by moving too soon.
"Contact the managing agent," recommends one. "Whoever is going to be paying the maintenance/listing the place will contact them. They can say 'We've had interest' to the family who is dealing with it. That way you know that they're ready to deal with the business affairs after the mourning process."
