Daily Mail on Top Form, Nearly

From The Daily Mail:

A dog trainer who once worked for Princess Anne is suspected of murdering his wife at the cottage where Boris Johnson grew up.

John Zurick, 67, allegedly shot his estranged wife Debbie, 56, after he discovered she had a new boyfriend. He then turned the shotgun on himself, friends said yesterday.

Paramedics were called to the cottage, on the Prime Minister's family estate in Somerset, on Saturday afternoon but were unable to save Mrs Zurick...

The Zuricks bought the property, where the Prime Minister spent some of his childhood, from Mr Johnson's father Stanley for £440,000 in 2013.

Stanley Johnson owns the neighbouring 14th century farmhouse on the Nethercote estate with his wife Jennifer. A third house on the estate is owned by the Prime Minister's sister Rachel.

Yes, yes, but what would the cottage be worth now (ignoring the murder-suicide stuff)?
