Unique industry specific regulatory, operational, and financing characteristics also appear to influence REIT leverage decisions. Specifically, REITs incorporated in Maryland use less financial leverage than their peers, while the availability and use of revolving lines of credit both appear to exert significant influence on firm leverage decisions. Furthermore, REITs concentrating their investment activities within either the Regional Mall or Manufactured Homes property type segments tend to use relatively high amounts of leverage, while firms focused on Self-Storage properties exhibit relatively low leverage ratios.
