The key word is "worth"!

The Mail reports that:

"Thousands of homes are being sold for knockdown prices at auction as banks desperately try to offload repossessed flats.

Properties worth a quarter of a million pounds last year are going for under £100,000 after families who failed to meet their mortgage were kicked out."

The key word here is "worth", I think they might mean "over-valued at". The property market has a lot further to fall.
