If you don't find a new place to settle down after selling the house, you can move out at the police station where the original account is located, but you need to provide some supporting materials, such as the house sales contract, ID card and household registration book. When you move out of your household registration, you can keep your ID card and household registration book, because these documents are still valid in other aspects.
However, if you have not moved out of your account for a long time, it may affect your personal credit record and related rights and interests. Therefore, I suggest you find a new location as soon as possible and go to the police station where your account is located to move in.
