Credit lines secured on dwellings are loans secured on dwellings where a certain credit ceiling is issued, usually within 60-80 per cent of the value of the dwelling on which the loan is secured. There are no restrictions on how or what the credit is used for. Interest is only paid for the amount of credit the customer has used at the given time. Fixed rates are not available for this type of loan. Only banks and mortgage companies offer this type of loan. Credit lines secured on dwellings were introduced in January 2006.
