Why Real Estate Investors Need an LLC in Illinois

Real estate investors face significant liability from tenant injuries, property damage claims, and environmental hazards. An LLC separates your personal assets from your investment properties, so a lawsuit against one property does not jeopardize your home, savings, or other holdings. Many investors create a separate LLC for each property to further isolate risk.
