The pictures from when you bought it are still visible on Rightmove on the sold prices page - they show that you haven't done anything in the 2-3 years you've been there other than massively increase the asking price. As a potential buyer I'd be put off that it was overpriced when it has an avocado bathroom suite, the same terracotta carpets, dated fitted bedroom furniture and a 1970s faux stone fireplace.
Are you getting viewings and, if so, what's the feedback? It looks clean and tidy, but it's a bit soulless - no pictures on the walls, etc.
