Market price is the price a buyer is willing to pay for a house
and is also accepted by the seller.
Price is determined by the supply and demand, in what condition
the house is in, and how has a similar house been sold in the
market without any value add on.
Factors that affect house prices are economic growth,
availability of funds, unemployment, building cost.
If demand of houses increases than its supply, price increases
and if the demand falls, price falls.
