In every aspect, Lewisville and Denton out paces Texas in most categories taken by the census. This is, again, due to the urban advantage that Denton and Lewisville receive.

With Dallas acting as the urban epicenter to Denton and Lewisville, Dallas brings more jobs, higher paying technical jobs, and an assortment of living options. These characteristics are beneficial to the area of north Texas when providing a large spectrum of variety, but with the downside of a higher price

According to Juliana Lee , since 1998 the prices of bay area homes have been increasing at a tremendous rate. In the 94022 zip code, up until the economic breakdowns of 2001 and 2008, prices had steadily grown from median-average prices of around $800,000 to over $2,000,000, then the recession happened and the market experienced a negative plummet in the prices to about $1,500,000 per home. (Lee) This left an opportunity open for investors who had survived through the recession as prices were then very deflated. The statistics show that people had realized this, and took full advantage of the situation, for during the years from 2008 to 2012, the average house was sold for 4% below the asking price. And from 2012 on, the average house was sold for 7%-11% over the asking price. What this simple fact demonstrates is that the suffering people go through during national economic downfalls is a prime opportunity for people who money and confidence to invest in housing and turn over a massive profit. This is the reason as to why people believe the saturated housing market in the bay area is actually beneficial.

Two economic factors affect supply in a stable housing market, price of related goods or similar houses, and the price of the good, best represented by style or size in the case of the housing market. The affluence of a community typically determines how much homes sell for in those communities, and therefore communities where a lot of people want to live become areas where average home prices are high. (Kumar, 1) There is little space in these affluent communities, and therefore little supply. A good example is New York City, where no homes are available, only apartment buildings, and very few apartments are actively exchanged each year.

For several years, interest has grown in the understanding of apparent determinants of housing price. Studies have shed light on this issue by identifying many factors where housing prices historically exhibit a high degree of statistical association. Economists Daniel Rubinfeld and David Harrison developed a dataset by means of matching data on nitrogen dioxide pollution in the Boston, MA, metropolitan area from the U.S. Department of Transportation with 1970 tract-level data on median house prices.

It is the common belief that increase in population greatly influences the value of real estate due to the fact that demand increases mostly in urban areas. This implies that migration of people from rural to urban areas affects the value of real estate and a perfect example of these is New York City where the prices of real estate continue to escalate as more and more people move to the urbanized city. Also considering that whenever the country’s population increases, the prices or real estate also tend to increase as more demand is created by the surplus population (Bodie, Kane & Marcus, 2008).
