The interior is tired as pp have said so I won't comment further on that.
The garden, however, looks like it has quite a lot of potential for a keen gardener. I don't know what it looks like now because the photos were not taken that recently, but you could get a firm in to tidy it up, weed and edge the borders, clean and empty the greenhouse and prune any plants that needs it. I'm suggesting employing someone because it's a lot of physical work and you probably have other things to worry about. (No, I'm not offering, I live a very long way from you!)
If you can show the property on a dry, or even better sunny, day I think the exterior might interest someone who is looking for a reasonably blank canvas to get to work on as a future project.
