You probably don't want to hear this... We're in Yorkshire, so not too far away. We put our house on the market last September and had no interest/no viewings. We took it off in November.
Over winter we completely gutted and refitted the kitchen (it was awful), then put the house back on at the same price. We had a couple of viewings over the next four months, though neither were proceedable.
However, I think our problems to this point were that, unfortunately, we made the wrong choice with the estate agent we went with due to friend connections.
We changed estate agents and after about a week or so with the new team started getting viewings, some of them proceedable. But unfortunately there is such a glut of similar low-cost houses in this area that they all found somewhere they preferred.
Then for the last fortnight or so it's just all dried up! I've spoken to the EA, asking whether we should drop the price, but apparently the market is just dead as a dodo right now around here - lots of houses for sale and very few buyers.
Have you spoken to your EA about whether the situation is similar in your area? Is advertising and holding an open day feasible? We did, and though no-one turned up on the day, some of our interest the week after came from people who had noticed the adverts for the house.
However... I'm sure someone will be along in a minute to tell you that your house is definitely overpriced, you're just being greedy and you need to cut your price by 20% and then expect an offer 20% below that.
