Some of the really big drops won't have entered the stats yet, because they are on properties that aren't budging.
For instance I saw a listing for a 2-bed flat, several sales in the block at or around £375k until 2021.
Listed at £375k, cut to £350, £325, most recent cut £300k.
So where will it end? Including the service charge, letting fees, provision for expenses/void, you most likely would need a £150k deposit just to break even, and that's forgetting you can earn interest on that £150k now.
So no surprise that something like this would have been snapped up by landlords at 1.x% rates but not today.
But it's like that for a lot of flats all around London.
Prior to last year people have been able to avoid crystallising a loss by renting it out, but the high interest rates have made that impossible for anyone on high LTV.
