I too have played detective. My honest opinion:
The bungalow is not in an area that most would aspire to if moving to the country. It’s quite a cheap area.
The artexed ceilings throughout would not appeal to many but I don’t know if they could be changed to plain skimmed ceilings whilst someone is living there - a messy job. They would certainly put me off, even if the property was otherwise perfect.
Most of the bedrooms are very small. How much furniture would fit in them, if you had a family and were looking for 4/5 bedrooms?
I doubt the kitchen is sufficiently large for a family to eat in, so that’s one bedroom lost.
People, moving to the country or not, often need a room to use as an office/study, so that’s another bedroom lost.
The range cooker and dishwasher are excluded from the sale, meaning that people either have to negotiate to buy them or find appliances which fit.
The grab handles in the bathroom are off putting to many buyers (even us in our mid-late 70s). Getting rid of them will mean re-tiling.
The plot is far larger than most people looking for a bungalow would want to look after, at almost half an acre.
Sorry, but I can’t suggest any easy way of making the property more appealing to buyers.
