Another characteristic of real estate is its lack of standardization. No two properties are exactly the same. Homes of identical configuration can be different in value because of location, upkeep, paint color, exterior condition, interior decoration or furnishing, and many other factors. Even if the physical features of two homes were almost identical, zoning, deed restrictions, or title encumbrances could make their values considerably different. 2. Location, or situs, is the third economic characteristic of land. Similar pieces of real property may have extremely different values just because of the difference in location. This difference can be caused by people's preference for natural attributes. such as weather, good soil, scenery, or for human made factors, such as schools, cultural attractions, or places of employment. 3. With other commodities, such as automobiles or food, a high demand or short supply in one area can be offset by moving products from other areas where there is an oversupply. This movement is not possible in real estate: therefore, home prices in one city may be considerably higher than they are for similar property in a city only fifty miles away.
