My view on this hex is that it will be difficult for you , because of obstacle. In fact you already have a business where you are working hard and where there is a income stream that is quiet ok and that you can manage. Addind this new business is possible but bring more headeache because seems that other haven't manage well his own business in past and there might be some legal or administrative issue with this. Usually before taking over a business in M&A process there is an audit. Maybe before getting into it you might want an audit that is more unbiased by a trusted professional or a trusted friend that know well that kind of situation ? (like checking cashflow, checking debt , checking value added, check accounting , contract with third parties ... )
