sell one business, which you know really well (if you got offer - i think you are successful and know business well), and replace it with another business (real estate), which you do not know yet and probably loose money during initial period... doesn't make sense for me.
That's a fair point, but unless you're going to roll it all back into the same type of business that you just sold, you're going to have to learn something new, either the stock market or real estate or something.
Ah. Then it's good when you want to learn new skill. I actually want to do this, but I believe retirement is something different. =)
Probably, we need to define what is retirement. =)) If it's doing nothing (business wise) - probably it's too boring anyway and learning new skills is good idea.
