According to WikiPedia, real estate is:
Real estate is a legal term (in some jurisdictions, notably in the USA, United Kingdom, Canada, and Australia) that encompasses land along with anything permanently affixed to the land, such as buildings, specifically property that is fixed in location Real estate law is the body of regulations and legal codes which pertain to such matters under a particular jurisdiction. Real estate is often considered synonymous with real property (also sometimes called realty), in contrast with personal property (also sometimes called chattel or personality under chattel law or personal property law).

However, in some situations the term “real estate” refers to the land and fixtures together, as distinguished from “real property,” referring to ownership rights of the land itself. [clarification needed]

The terms real estate and real property are used primarily in common law, while civil law jurisdictions refer instead to immovable property.

Real Estate Agent?! Who is this? What it do?

Again according to WikiPedia: Real estate broker or Real estate is:

A real estate broker is a term in the United States and Canada which describes a party who acts as an intermediary between sellers and buyers of real estate (or real property as it is known elsewhere) and attempts to find sellers who wish to sell and buyers who wish to buy. In the United States, the relationship was originally established by reference to the English common law of agency with the broker having a fiduciary relationship with his clients.

Estate agent is the term used in the United Kingdom to describe a person or organization whose business is to market real estate on behalf of clients, but there are significant differences between the actions and liabilities of brokers and estate agents in each country. Beyond the US, other countries take markedly different approaches to the marketing and selling of real property.

In the US, real estate brokers and their salespersons (commonly called “real estate agents” or, in some states, “brokers”) assist sellers in marketing their property and selling it for the highest possible price under the best terms. When acting as a Buyer’s agent with a signed agreement (or, in many cases, verbal agreement, although a broker may not be legally entitled to his commission unless the agreement is in writing), they assist buyers by helping them purchase property for the lowest possible price under the best terms. Without a signed agreement, brokers may assist buyers in the acquisition of property but still represent the seller and the seller’s interests.

In most jurisdictions in the United States, a person is required to have a license in order to receive remuneration for services rendered as a real estate broker. Unlicensed activity is illegal, but buyers and sellers acting as principals in the sale or purchase of real estate are not required to be licensed. In some states, lawyers are allowed to handle real estate sales for compensation without being licensed as brokers or agents.

Real Estate Investment:

Real Estate Investment is now treated as a major case of capital budgeting by using state-of-the-art investment analysis which incorporates the future stream of income it may generate and the associated risk adjustments. It has been the highlight of the investment literature since the 1970’s when investment theorists extended techniques such as probability, time value of money and utility into its analysis.

Real estate is basically defined as immovable property such as land and everything permanently attached to it like buildings. Real property as opposed to personal or movable property is characterized by the right to transfer the title to the land whereas title to personal property can be retained. The investment in real estate essentially depends on the risks associated with it, that is to say, even if the venture succeeds when the future stream of income will accrue to the investor and the alternative investment opportunities. Real estate investment can be attractive if viewed as a business opportunity; it can generate rental income, using it as collateral to secure a loan for a business venture, to offset otherwise taxable income through cash savings on tax-deductible interest rate losses, or simply from the profits garnered from its resale. Notable, in this context is the gains reaped by real estate speculators who trade in real estate futures (by buying and selling purchase options).
