Doesn't that big brother couple live in Brighton? Preston and Chanelle/Chantelle whatever her name is. They've just split up so could explain why its on right move (!!!) but not sure if they could afford to live there !!!
If I had the choice I would live in South Birmingham, Curry Alley. Brighton is not known for good vindaloo shops although there is a decent specialist store just up from the multi-storey. Paul McCartney lives in Kent anyway and gets most of his takeaways from Rye.
I reckon it'll be Derek's or Macca's. Think the Slim's would have a funkier choice and if they put up the house for sale would they not put up the recording studio too? Perhaps could be Nick's but I reckon it's the Macca or the Jameson's. With all that's going on in Macca's life perhaps he's had enough and fancies moving!
