My view is the house is very badly marketed. The first picture should be a close up of your house only. The picture of the field should be at the back. I would think that's more a deterent than attribute. Lack of privacy, noise of kids playing in front, and the path? Where does it lead too? My first thought is too many people passing by, security worries.
The pictures could be better angled so the rooms look bigger. Finally the garden. The most likely buyers of a 4 bedroom house in what looks like a residential area will be parents with kids. Your garden is not appealing to these buyers and therefore takes away the largest chunk of the market.
This alone will significantly impact on the price, so you need to consider if you want to redo the garden.
I was in the exact same situation. Our buyer (after 7 months on the market and only over a handful of viewers) planned to totally redo.our garden. We lowered the asking price by £50k to make it competitive to take this in consideration.
