It's a repossession - you can tell from the wording in the blurb. They are obliged (in theory) to get the best price for the lender, hence inviting offers over what they've already got. I would suspect that the price was set a bit low at first to encourage bidders.
Still seems a daft price for a studio flat, albeit in what has be one an expensive area, given that the lease is only 69 years. Will be expensive to extend since the cost goes up substantially once the lease goes below 80 years.
