When I ask this question, I'm referring to valuing an entire business, not just the property on which it sits or the property and a building. So if A wants to buy B's plumbing business and A wants to determine the value of the business based on and including income, liabilities, good will, the value of property and buildings and other assets, can appraiser do this? What professional designation would you need? How do you examine the books? How large of a company can you realistically value? Would this be better accomplished by an accountant or an investment banker? Thanks in advance.
