An existing business has a track record. The failure rate in small business is largely in the start-up phase. The existing business has demonstrated that there is a need for that product or service in a particular locale. Financial records are available along with other information on the business. Most sellers will stay and train a new owner and most will also supply financing. Finding someone who will teach you the intricacies of running a business and who is also willing to finance the sale can make all the difference.
