This is good advice OP, and if you don’t know how to do this, find someone you know and trust who does and ask for their help. If the business is doing decent, doesn’t have much debt, and you think you can add value to what they’re doing already, it could be a great opportunity. If they have declining revenue, aren’t making much profit and have sizable debt, not a good idea. So don’t make a decision either way until you see some numbers you are confident in.
