What type of business is it? I have bought and sold allot. Mainly properties and assets but I have bought and sold some companies. Contact me via PM if you want to give me a little more info so I can help you out. Buy low and sell high is a good way to go usually. If he is desperate to get out of the business you could get a very good deal too as most business are very hard to sell, especially one that already has a partner who owns 49%.
