Have you got a Solicitor because they would answer these questions for you?
We opened a Bank Account because we have a CAM Mortgage and it was an easy way to hold funds for the charges- which PW will want to know you have done, and to transfer the mortgage money to and from.
Have you signed all the mortgage paperwork, authorisations for community charge direct debit and utilities connections?
We used SnagitMurcia because although we could be the initial snag we couldnt gaurentee being there for the return visit to check work was done. Snagit were very thorough and as PW didnt do everything they said they would Snagit sorted all that and signed everything off for us. That was very useful as we couldnt get back to confirm things and we actually dont trust PW when they say they have completed things. ( we saw this in action when we were in our apartment and workmen came in to check the wardobe shelving and although the bedroom doors were on their list (dragging) they clealry had no plan to sort those during the wardrobe visit- until we made them)
Some people stay overnight to manage their completions- if you know eveyrthing is in place and you have the NIE then this could be all the time you need. However, bear in mind that twice CAM weren't ready to complete on the dates planned for us- confusion all around. We did it all by POA and are glad we did because one side didnt seem to know what the other side were doing (twice) despite having the Hab Cert. Kept having to force the cork back into the champagne!!!!
