Fees for a due organization opinion letter typically run between $2,000 and $5,000, depending on the size of the loan and the number of companies involved. The more companies that are involved in the process, the higher the fees will be. In addition to the fee, the lender may also require a deposit or other security. The amount of this deposit is usually based on how much work is required to prepare the letter and what is considered reasonable compensation for those services. For example, one common fee structure is to charge $10,000 with a deposit of half of the fee ($5,000). If more than one opinion is needed, the additional costs will be charged to the borrower. The due diligence process can be time-consuming and detailed, so it's important to select an expert company with sufficient experience to provide accurate information. Due diligence generally includes questions about a company's management, employees, partners, investors, locations, products/services, finances, legal issues, and more. The scope of this review depends on how deep the lender wants to go into detail - some consider only certain types of issues while others will investigate every aspect of the company's operations. After the initial research has been completed, the company will send the lender a copy of its written opinion along with a statement of fees incurred.
