*B6 Mrs Laura Stapleton, a widow, has decided to dispose of her residence and retire to Canada, where she will live with her son, Danny.

She acquired her house on 1 June 1990 and lived there until 31 March 1991 when she left the UK in order to care for Danny and his wife who had been injured in a serious car accident in Canada. Liking it there, she extended her stay and on 1 November 1991 she took a job at a local hospital until 31 December 1992 when she returned to the UK and resumed residence in her property.

She remained living in her house until 31 December 2004, when she left it permanently in order to live in a flat. Contracts were exchanged for the sale of the house on 31 May 2009.

The house originally cost £50,000 and an extension was completed in December 1993 at a cost of £20,000. The agreed sale proceeds are £300,000 and the expenses of sale are

£5,200. Throughout the periods of Mrs Stapleton's absence, the property was let at a market rent.
