Asking price down by over a third.

Forest Court, Edgware Road

I see this kind of flat as an important bellwether.  508 sq. m. and still above half a million pounds.

Previous sold prices don't seem to support that kind of valuation.

Cadogan Street

This flat appears to be above an office of Strutt and Parker.  Douglas and Gordon however can't get past the new stamp duty threshold.
