The biggest problem is the atrocious photos. Your second photo, after the exterior one, needs to be a “wow” picture of something like the living space or kitchen, preferably making it look as large and appealing as possible. Your second picture is of a wall and two glimpses of loos that are right next to each other. It’s off-putting. The idiot agent has also climbed into the bath to take another unnecessary picture of the same bathroom that already has other pictures. So, better pictures with some sort of continuity are necessary. Is that utility area still there? Why no photo of that?
The exterior looks like a stable or something, especially with the garage door and the paved yard area in front. It needs some sprucing so that it says “home.”
Can the garage fit a car? It doesn’t look like it. If not it needs to be relabeled imo. If it can there needs to be a photo to better show the size.
The grey is awful. This country is grey enough without bringing the grey indoors as well. I suppose there’s nothing to be done about the dated, unappealing charcoal carpet but the stairs and some of the walls can at least be painted and the bedding changed. When going for neutral always choose white or beige over grey, which often comes across as cold and depressing especially in a house as empty as this.
I think those are the easiest ways to gain some interest. The kitchen is very dated but would be expensive to redo. Unless that weird green is a covering that can be removed, rather than paint? I think the pale wood is more appealing and could have been left alone if not being replaced.
