Is now the right time to buy the business I've managed for 7 years?
Okay, there may be exceptions. Sometimes certain kinds of businesses go through hard times, like maybe real estate brokers or mortgage brokers for example during a credit crunch. Maybe you're an exception.
More likely, though, is that you know much better than I do. You work there, you've seen the ups and downs, and you know the ins and outs. Don't look for magic answers somewhere else, find the answer right there with what you know and think and feel.
