Chief executive Gerard O’Keeffe said: “In the current climate, it is very difficult to access mortgages without very large deposits and many lenders have withdrawn high LTV mortgages.
“We would like to offer our members access to a 90 per cent LTV mortgage product.
“We know that this is meeting a real need, particularly for first-time buyers and young people looking to get a foothold on the property ladder, who can afford mortgage repayments but do not have the larger up-front deposits now required in the market.”
