Not building a team of experts

At a bare minimum, you should enlist the aid of an attorney and a CPA. The attorney can prepare and review documents, help structure the deal, and make you aware of legal and liability issues. The CPA can provide a financial analysis of the business, and advise you about tax and accounting matters. You should consider adding a business valuation professional. His valuation report can be used to determine the reasonableness of the asking price, negotiate a lower price, and provide valuable information about the business, the industry, the competition, and the economic conditions.
