Hello and thanks for using Just Answer.
My name is ***** ***** am happy to assist you with your enquiry.
The Sellers Solicitors are under a legal obligation to redeem all Mortgages on completion of the Sale, so you have nothing to worry about.
However, as with all Auctions, I would advise that you get a local Solicitor to check the searches and title for you, before the Auction.
Please let me know if I can be of any more assistance.
