Is it possible that you and you alone are the only people who can see past the grot to its potential?
So many people can't see past what is really just old fashioned or shabby decor or bad layout and often dismiss a property from awful pictures alone, without even viewing.
If the bones of the house seem ok, and you can see potential, I wouldn't let the fact that it's not sold for a year put you off.
Our bungalow was dire, and the photos reflected that. It was on the market for over a year, dropping in price every few months, until one day we realised that if they were now to take a 'cheeky offer' it might be worth going to view. We viewed it and offered low, and they accepted. I think ours was the only offer they had over the whole year.
We knocked a wall down to open it up and change the layout and a window to a door, re-roofed the conservatory (previously had a plastic roof) and put in new windows throughout and a new bathroom and kitchen and now it is lovely. We landscaped the garden ourselves and it is now unrecognisable from when we moved in. And worth a great deal more.
I'm sure people thought we were mad but we could see the potential and it was in the location we wanted. No regrets.
