Connecticut Real Estate School, Licensing Classes, Continuing Education, On-Line and In-Class. Real estate transactions are taking place all around you, all the time. When a commercial leasing company rents a space in a mall or the owner of a building rents an apartment to a retired couple, it’s a real estate transaction. If an appraiser gives an expert opinion on the value of farmland or a bank lends money to a professional corporation to purchase an office building, it’s a real estate transaction. Most common of all, when an American family sells its old home and buys a new one, the family takes part in the real estate industry. Consumers of real estate services include buyers and sellers of homes, tenants and landlords, investors and developers. Nearly everyone, at some time, is involved in a real estate transaction.
