Whether your potential home is in the city or the country, CitiMortgage wants to help you buy it. Or fix it up. The mortgage lending unit of Citigroup, CitiMortgage originates and services residential mortgages throughout the US. It manages most of its parent's $170 billion mortgage portfolio. CitiMortgage also offers refinancing and investment products. The company sells through retail, online, and correspondent channels.
