Where is the REI main headquarters?

Could you please clarify for me where exactly the main headquarters of REI, or Real Estate Investment Trust, is located? I'm curious to know the specific city, state, or even country where this important financial institution has its primary base of operations. Understanding the geographical location can offer insights into the company's regional focus and potential market reach. Is there a specific address or landmark nearby that might help in locating it? Thank you for your assistance in this matter.
