The Whiteley, Hampshire-based company is spending £230,000 on the competition, which it believes could be the most lucrative of 2003.
David Wylie, Managing Director of County Mortgages, said: 'We are investing a lot in this year's competition, which must be one of the most generous in the mortgage industry. '
All cases must be accompanied by County's application fee and meet the lender's initial underwriting criteria. The competition runs from now until November 28, 2003.
