Frankly it’s the price. People evidently don’t feel the house is worth the cost. I don’t see it either. Also every single photo has junk, I’m not sure how you can’t see that. It looks like the starting point of hoarding! It’s quite chaotic. Even if you cleared the clutter, it’s still not worth the asking price though. As you asked for examples:
#2 - full to the brim bookcase with lots of junk on top, lots of stuff in/around the tv stand. Makes me think there’s not enough space inside.
#3 - every single shelf including the windowsill is full of junk. Even the crawl space between the counter and the wall, and the side of the toilet! It looks trashy
#4 - why are there random things on top of the wall counters? All the counter space is occupied too.
#5 - this photo actually is difficult to look at. It’s visually chaotic and hurts my eyes. This goes beyond “clutter”, I’m looking at this thinking it needs a skip. That huge sack in the corner is concerning.
#6 & 7- every surface covered in clutter in both bedroom & bathroom
#8 - why is there junk on the windowsill?
#9 & 10 - filled to the ceiling with junk, every surface is covered
#11 & 12 - more junk everywhere. Is that a bunch of stuff hanging off the door in the left of #12? Why is the radiator placed so high? Why is there stacks upon stacks of stuff?
#13 - what is this photo’s purpose? It comes at a random point in the listing and isn’t particularly attractive
#14 - again, junk everywhere in the garden, but you can also see into the horror that is the conservatory and all the junk inside too.
