Real estate businesses need several types of insurance to protect themselves, their clients, and their investments. Some of the common types of insurance that real estate businesses may need include:

1. General Liability Insurance: This insurance provides protection against third-party bodily injury, property damage, and personal injury claims.

2. Professional Liability Insurance: Also known as Errors and Omissions (E&O) Insurance, this insurance protects real estate businesses against claims of negligence, errors, or omissions in their professional services.

3. Property Insurance: This insurance covers damage to property owned or leased by the real estate business, including offices, equipment, and other assets.

4. Business Interruption Insurance: This insurance provides coverage for lost income and expenses incurred as a result of a covered loss, such as fire or natural disaster, that interrupts normal business operations.

5. Workers' Compensation Insurance: This insurance is required by law in most states and provides coverage for work-related injuries and illnesses suffered by employees.

6. Cyber Liability Insurance: This insurance covers losses arising from data breaches and other cyber-related incidents.

7. Umbrella Insurance: This insurance provides additional liability coverage above and beyond the limits of a company's primary insurance policies.

The specific types and amounts of insurance that a real estate business needs may vary depending on the size of the company, the types of services provided, and the risks associated with the business. It's important for real estate businesses to consult with an experienced insurance agent to assess their unique insurance needs and develop a comprehensive insurance program.
