The stove and the fridge are considered "personal property", which means they are not something permanently affixed to the dwelling/building. So, it's legal for you to take them. Some people do. I would say it's more appropriate if you actually purchased these items separately rather than they were part of the home when you purchased, but follow your own heart. If it's what's best for you and your family, then that's what you should do.
Good luck to you!!
