There are a zillion different moving guides online with all sorts of tips, tricks and reminders.
But honestly, for our move, I found that using an online To Do manager with different lists for things like “Timeline”, “To Buy”, “To Pack”, “To Fix – Old House”, “To Fix – New House”, “Contact Info”, etc. (but yes, borrowing ideas liberally from those other online sites) was the best tool to keep track of all the various elements of our move.
