After finding a business that is for sale and that seems a likely prospect for you to run successfully, you should spend enough time to thoroughly investigate the business. You should definitely get your lawyer and accountant involved in this process, as well. By thoroughly investigating the business (doing "due diligence," in business-speak), you increase the chances of making a decision that is right for you. The time spent investigating the business, the industry, and the market will make you confident that your decision to buy (or not to buy) was the right one.
