Local government has the most influence on real estate markets. It affects the supply and cost of real estate through zoning and land use regulations, fees on new land development, and restrictive building codes. It also affects rental rates through the assessment of property taxes. Finally, local government affects the supply and quality of real estate through the provision of community infrastructure and through building codes. The Federal government influences real estate through income tax policy, housing subsidy programs, federal financial reporting requirements, fair housing laws, and disclosure laws. State government generally has the least influence on real estate. State government affects real estate through the licensing of real estate professionals, establishment of statewide building codes, the creation of fair housing and disclosure laws, and through numerous housing related subsides for low and moderate income households. In addition, the state may protect some environmentally sensitive lands from development.
