Not everyone wants to start a business from scratch. There is a certain attraction to coming into a business that has a history and has grown over the years.
It has a location, a name, the necessary permits, customers and cash flow. Compared to a start-up there is a lower level of risk and a greater chance of getting financing.
However, one must do their due diligence. You must make sure that there is a history of profitability. Hire an accountant who specializes in business valuation to analyze the financials to make sure that they are what they say they are.
