||After decades of development, America's real estate industry is now playing an important role in the economy. Housing consumption has become a big driving force to expand domestic demand. But in the last few years, America's housing prices rose faster than the increase in overall economic growth especially the increase in the income. The excessive growth trend in housing prices not only greatly affects the life quality of urban residents, but also is a destabilizing factor in the development of the entire national economy. The housing price issue has become a widely concerning problem. Based on this fact, I will use econometric analysis methods to figure out what factors influence America's housing price. This can provide some references for investors, mortgage banks or individual buyers.
