S17·E21 Hotel Folly - Folie a Deux

Filmed over five years, this is an emotional rollercoaster of a documentary which explores the sometimes extreme highs and lows of one of life's biggest gambles - buying a home.

Helen has seven children, a new partner and a very comfortable lifestyle when they decide to get a mortgage to buy one of the most historical houses in England. They want to convert the shabby 72-room mansion in the centre of York into a tasteful hotel, but when the financial crisis hits their dream turns into their worst nightmare.

For five years, feisty Helen fights the banks for a loan for the spiralling renovation costs and her neighbours over rights to the courtyard. While her house gradually becomes unsellable, she persists with her neigbourhood wars.

Part black comedy, part nail-biting journey, this shows the human cost of the mortgage crisis.
