Thing is people sell for a reason. Buying paysite programs is risky business and that has to be built into the price ... and if someone is selling as an 'opportunity to build the program' lets not forget the program still needs massive promotion and lots of $ sunk into it. Programs that are making good money and on the upward are rarely ever sold .. its only programs that are stagnating or in a downward sales trend that are ever up for sale regardless of the reason given for sale.
Sure content, domains and other things need to be taken into account, but sites with simply amazing content and/or domains very rarely need to be sold because they make good money already
Yes in the general business world 12 months minimum, but this isn't the general business world.
