Having outgrown their two-bedroom flat, media relations officer Adam Smith, 29, and his partner Claire Brand, a 27-year-old police photographer, were ready to move on to a bigger place in Reading.
They offered their home at £189,950, but accepted £175,000 from a young Eastern European couple who said they were first-time buyers and were eager to move in quickly.
Adam and Claire then found the house they wanted: a £310,000 semi being sold by an elderly widow who wished to move nearer her son.
The widow was actually signing the final paperwork in her solicitor's office when Adam called to cancel the deal. He had no choice.
The young Eastern Europeans had just dropped their offer to £150,000, and when he told them he simply couldn't afford to absorb a £25,000 reduction, they pulled out.
