If you look at the house you linked, on the same street for £25k more, it is end terrace and has a proper garden room/studio. Which means yours looks overpriced in comparison, as they have an extra room
and only have one neighbour.
Your staging and photos aren’t nearly as good, although your house seems very clean and tidy, as other have said it is full. Their 2 smaller bedrooms are almost exactly the same size as yours, but look so much bigger and are being sold as 3 bedrooms.
They also have a photo of their garage, whereas you don’t, so I didn’t think you had one.
You should use your garage for storage. Get all your exercise equipment in there. And half the contents of your wardrobes & cupboards, so you have somewhere to put your shoes. Also store the work desks, office chairs & files.
If you can’t work from laptops, set up small desks in the corner of the smaller two bedrooms, with a normal chairs.
Move excess stuff off counters in kitchen, and see if you can get a much smaller white fridge & store yours in the garage until you move.
Yes it’s annoying to do, but you want your house to sell, and it’s a small price to pay to store your things and sell a lifestyle rather than an outgrown house.
Pressure wash the front and back.
Add some colour and a garden set
Can you also pressure wash the green staining on the front wall, around the loo window?
Add beds. Use the sofa bed dressed as a bed in the box room, & get a proper double for the bigger one.
Fix the bathroom basin cupboard doors/replace the doors, and paint the unit as it lets the otherwise ok, clean but slightly tired bathroom down. Add colour with towels and plants.
You don’t need to buy things, I stage to sell, -we’ve moved a lot- with free stuff from Facebook or gumtree, & list them free again when sold.
And start with an exterior house photo, or the ad screams that there is a problem either ugly house or another issue that they tried to hide, & people scroll on without even clicking.
