Our minimum age for joining as a house sitter is 18 (and we have no maximum age). Please also note that by joining our service, you won't be committing to anything.
Please note that the way that MindMyHouse works is by bringing home owners and house sitters together. What home owners and house sitters agree to after they have made contact is often private and we are not always privy to that information. If you (or they) have particular expectations (eg. age, payment, food etc), it's best to ensure that you and the home owner communicate your expectations with each other before you agree to house sit for them.
