I See what your saying, i think the house that are cheaper are the ones in the actual village and on busy roads and don't have that country side feel, we are in the country side. thanks that's an interesting point.
Kindly, you seem to have a bit of a 'thing' about being in a quiet road.
Many people are not so bothered and, even looking at street view, it's hardly a main road- it's still relatively rural.
Your house has some issues which reduce the pool of buyers.
In some ways it's attractive as a 'downsizer' house or a first home.
But the length of the garden (note- it's dimensions are not even in the details!) will possibly put off older buyers who don't want the upkeep of such a lot of lawn.
And for younger buyers with children, there is no eat-in kitchen only a living room/ diner.
As a 4-bed it doesn't have the space downstairs. Anyone with children/ teenagers needs another reception room, not just one.
You could perhaps market it as adaptable living, where one room upstairs became another living room/ study but to do that you need to dress it as such- make it an office with a desk and shelves. Or put a bed and furniture in one of the 2nd floor rooms so buyers can actually see that a bed fits the space.
I think the issue is you've got used to living there in a way it suits you, but you can't imagine how the space might not work (or work with some alterations) for other people.
