The U.S. housing market is comprised of buyers and sellers of homes in the U.S. This information encompasses the supply and demand for homes as well as the inventory level of unsold homes. In different markets around the country, you will have a natural progression of demand and supply. In some markets, there are new citizens moving to the city creating demand and, unless there is enough supply to match this demand, prices will rise. Varying degrees of income levels and job growth play a role in determining how many transactions occur in any given housing market.
