Nationwide Building Society is reducing interest rates on some of its fixed-rate and tracker mortgages this week, with rates on its fixed loans for house buyers falling up to 0.07%. A two-year fix is available from 6.58% with a £599 fee ... The loan itself is made by a bank, a savings and loan association, a mortgage company, a credit union, or any other lender. For it to become an FHA mortgage loan, the lender would have to be approved by the Federal Housing Administration.
