House Sitting is a protective measure for homeowners who do not wish to leave their home unoccupied. There are also safety considerations for House Sitters, especially those who are staying in the home of someone they do not know. As a House Sitter, you should always interview the people you are sitting for to gain a sense of where the home is, the safety of the area, and if anyone else is in possession of house keys. A third-party app or service may vet users, but it is important to use your best judgment and feel free to say no to situations that are uncomfortable.
