This is definitely not a 4 bed house. I can’t see how the estate agent can put that and keep a straight face.
Nearby similar designed property went for £1.1 million at the end of 2017 but that place was beautifully done, they have a bathroom on the first floor and they have gone up into the loft to create 2 more bedrooms and a further bathroom.
At £800k with all the work that needs doing I think that is a top price.
