Mortgage Intelligence, part of Countrywide, supports brokers selling mortgages and insurance.
Cameron Amaira, head of intermediary sales at National Counties and Family Building Society, said: “With our appointment to the panel, members of MI can now access our range of innovative and niche products and services.
“Some 80-90% of the loans offered by the National Counties Group are distributed via intermediaries and the link up with MI will strengthen this bond with the broking community.
National Counties handles each application on a case by case basis, while Family Building Society provides family, low start and offset mortgages.
Sally Laker, managing director of Mortgage Intelligence Holdings, said: “Their unique proposition provides access to their individual underwriting approach and non-mainstream criteria.
“In the current market this offers our advisers opportunities to assist client’s where they may not have been able to assist before.”
