If you are currently renting, notify your Landlord, using the proper notice. Otherwise, your tenancy may not end legally. Check your tenancy agreement for details and information about your deposit protection. 

Check out your new area before purchasing your new property. Check out for any local newspapers, blogs, or community websites. Start ordering and collecting boxes. Notify your land phone provider for the change. Tell them at least a month in advance if you are cancelling. Notify your internet provider for the same reasons.
