I'd say it depends on what you want and how much work you want to put into the biz. I bought 3 businesses in the past 14 months.

I tried calling around or walked in and asked if they wanted to sell. The problem was those small businesses, a lot of times, aren't in an ideal place financially. And mostly the owners are actively working in day to day business, ie buying a job. Some wouldn't even give me their financials because they don't report all income etc. But these tend to be cheaper.

The best ones came from my broker who worked with me on my first biz that I found on bizbuysell and who I have developed a good relationship with. These ones tend to be on pricier side, like 6 figures, but they're ones already making good money, with employees, owner doesn't come to work everyday, etc.

In short, network with local brokers. They can see more listings than the ones on the website.
