Depends on your motivation mate, but TBH if you've priced it at 10k and then are considering breaking it i doubt you'd get that.
If it was me (and it isn't) I'd save the hassle of fcuking about breaking it and sell it for £8500, but i noticed that you don't really need to sell it, so I would just keep a hold of it if i were you. Good luck whatever u decide to do, personally there is no way I would sell it.
