Flat has been on the market since December. Now on with a second agent. In that time we've had six or seven viewings and no offers. There are four or five others in the same block (all virtually identical) up for sale. We've already dropped our price so it's one of the two cheapest, despite being in good condition, but just nobody will come and look. I'm losing the will to live a bit!
NB: this is mostly a rant - I realise it's unlikely that anyone has a magical house-selling secret. But worth a try...
