Edeus, the specialist mortgage lender, is offering borrowers a discount of up to 8 per cent if they redeem their home loans and take them elsewhere. The offer from Edeus, which deals in sub-prime, self-certificated and buy-to-let mortgages, has been triggered by the credit crunch. Edeus used to generate cash by selling its loans to other financial groups but, in the past year, demand for such loans has dried up. Organisations prepared to take on the loans are demanding such high discounts that Alan Cleary, managing director of Edeus, has decided it would be cheaper to go directly to borrowers.
