@Brendan Viehman One of my hats is as a business coach. I can safely say that, unfortunately, many business owners undervalue their businesses. If you get someone who is not savvy, they may see a lot less value in their business than it really has.
A great example of this is my own parents. My dad has owned a limousine company for 25 years and he doesn't think his company is worth anything, because the cars are all used and he doesn't see a value in his book of business. fortunately, I'm working with them right now to build their business to sell for a lot more than they thought it was worth. Sadly many business owners start running their business down into the ground when they are ready to get out.
There are opportunities abound, however, you need to do your diligence and make sure that the busisnesses as good as it looks. You really want to be knowledgeable about the industry you're getting into, so that when you are looking at the P&L, you know that all of the expenses are accounted for. IMO, I would pick a niche or an industry and focus on becoming an expert in that area, as opposed to looking at this as a generalist. You are far less likely to walk into a mess you don't understand.
