True, a tough challenge if we buy or continue an existing business is that many people feel they are in control and sometimes it is difficult for us to control, companies that are being sold usually experience complex problems from production to marketing, making a new business is of course better so that all control is in our hands.
The most important reason why someone start a business is to earn profit, if the owner willing to sell his business, it's mean the business is failure or not making a good profit. Why the owner want to sell his business if he can make a lot profit and expand his business? it's not make sense right?
That's why, when someone want to sell something where it's related with making money, you're need to be very very careful.
There are only two options on it that most likely will happen: the owner can't deny the proposal because there is huge money involved, which means that if a person buys that, he can earn huge money to start another business or even multiple ones, and the second one is that the owner of that business sees that his business is not worthy now or anytime it goes down. But the first option, which is mostly what is happening right now, is that they can't turn down the big offer if the person wants to buy it.
