To help your broker successfully sell your commercial property, you should provide them with as much information as possible about your property. This may include details such as its size, location, and features, as well as any financial information such as revenue and expenses, in the case of an investment property. Other relevant information may include zoning, building or environmental reports. The more information your broker has about your property, the better equipped they will be to accurately price it, market it effectively, and negotiate the best deal possible with potential buyers.
