Work backwards from the day you get keys. Two weeks out: start the Prince William Water account, set up electric and internet, get the HOA's or landlord's written move rules, and book the move through the Triangle moving page. One week out: confirm the truck plan and the backup date, plan the cleanout channels (hauler route, county facilities with the ID check), and set aside what travels with you. Start school registration and records transfers before arrival, not only once classes begin. In the first days, learn your hauler's day and confirm utilities actually work. If you are moving from another state, use the Virginia DMV new-resident checklist for licensing, title, registration, inspections and deadlines; Prince William is listed for emissions checks. Review your own eligibility and any military exception with the responsible agency. Update the postal address, insurance and voter registration where applicable.
Keep a Plan B for the failures that matter here: a moved report date or closing (the backup moving day, agreed in advance) and a delayed key handover (which items go to storage, which travel with you). The guide's sections hold the details; the moving page holds the estimate.
