As a business broker I hear this question fairly often. My answer is "Why would anyone want to sell a good house or a good car...because something has changed." The owner may be ill or ready for retirement. Maybe he/she has another opportunity they want to pursue or they just want a change of scenery. Sometimes a divorce is pending or other personal or family considerations are pressing. Just like good houses and good cars, good businesses are being bought and sold every day. As always - pay attention and beware of the lemon.
