This study analyzes the market share of the top 10 home builders in nine Metropolitan Statistical Areas, along with fourteen other independent variables, to find a statistical relationship with median home sales price. Through a stepwise regression of the independent variables it is determined that there is no correlation between median home sale price and market share of the top 10 home builders. In the stepwise regression two variables are found to be correlated to median homes sales price: Owner Occupancy Percentage and Residential Construction Wages, a data point compiled for this study. A linear regression is run between market share of the top 10 and median home sale price and no correlation is found. / Master of Science / This study observes changes in median home sale price and changes in the market concentration of the top 10 home builders. Data from nine cities was analyzed. Using linear regression with the two previously mentioned variables along with fourteen other variables the study finds no relationship between the two variables. Among the variables the two that had the highest statistical relationship are Owner Occupancy Percentage and Residential Construction Wages. This study is relevant to the on-going discussion about concentration in the housing market.
