REAL ESTATE PROPERTIES good and actually points to an understanding of the same and can be referred to simply as BUILDING. BUILDING herein refers to "all forms of physical buildings, which are either in the form of permanent, semi-permanent or temporary, along with the earth in which he stood up to a depth of infinity" (if the sky / air above includes the right BUILDING whether they will be, for a while I can not answer, perhaps next time)
PROPERTY initially referred from the original word in English that is actually PROPERTY leads to legal aspects / legal form of rights and ownership of a building.

REAL ESTATE derived from uptake logged in word that exactly the same, which is actually jg is a loan word that was originally derived from Spanish. REAL = royal = kingdom, ESTATE = land (agricultural / garden). so that it can be interpreted as an area of ​​land which is controlled by kings, nobles, and the landlord (landlord feudal society of the mid-century) or that is controlled by the conglomerates, the rich and the masses in general, although in a very unequal portions and small (in the era industrial and information age today)
so clearly here both said property and real estate refers to the same notion that building (either in the form of ownership rights along with the land where he stands).

but lately there has been a shift in the meaning (which actually does not mean negative), the property is leading to a single building or a massive, ie one unit of a simple house type 36, or a fancy house with a courtyard area of ​​a conglomerate acres hectares and tens of billions of dollars , or 1 unit shop, or 1 building as high as 30 floors, or 1 complex mall or 1 hotel complexes etc. meaning more properties leading to a building that more / dominant (both in terms of price or volume) of the composition of the building itself than the soil.

while real estate is defined a complex of buildings that have a landscape (land and environment: parks, roads, waterways) with kompiosisi that dominant, practical examples of this term, if we mention one word of real estate most laymen would envision a residential area which is spacious and beautiful, ideally example is the work of a complex work of township real estate guru Indonesia Ir.
