A Mortgage Investment Corporation (MIC) is a company that allows people to invest in mortgages. When you invest in a MIC, you are lending money to people who need it to buy a home. Your money is pooled with other investors' money and used to make loans to people who are buying homes. When those people make their payments on their home loans, the MIC pays back the investors. So if you invest in a MIC, you can make money and help people buy homes at the same time.
