Mortgage finance companies provide funding for people or organisations buying, refinancing or improving property. Their main activity is lending money secured against property, usually through residential mortgages, but some also finance commercial buildings, property development or specialist situations. They assess applications using information such as income, credit history, the property's value and the proposed loan, then set the loan amount, term and repayment structure. Customers may be able to choose between repayment and interest-only mortgages, fixed or variable interest arrangements, and loans for different property types or circumstances. Some companies also arrange further advances or refinancing, manage mortgage accounts and collect repayments. If a borrower falls behind, the lender may discuss repayment arrangements and, where necessary, take steps to recover the debt.
