Real Estate Directories Directory Directories Directory for Real Estate - The terms real estate and real property are used primarily in common law, while civil law jurisdictions refer instead to immovable property.With the development of private property ownership, real estate has become a major area of business. Purchasing real estate requires a significant investment, and each parcel of land has unique characteristics, so the real estate industry has evolved into several distinct fields. Specialists are often called on to valuate real estate and facilitate transactions.In most jurisdictions mortgages are strongly associated with loans secured on real estate rather than other property (such as ships) and in some cases only land may be mortgaged. Arranging a mortgage is seen as the standard method by which individuals and businesses can purchase residential and commercial real estate without the need to pay the full value immediately. See mortgage loan for residential mortgage lending, and commercial mortgage for lending against commercial property.
