When folks invest into property or stock, they normally have a pretty good idea of when and how they will exit the position BEFORE they decide to buy. The who doesn’t matter nearly as much as it does in exiting a business.
The is no deep, secondary market for private businesses. It’s actually really hard yakka to execute.
Lots of people wait until they are burned out to start the exit process and are simply blindsided by the reality of how hard it is.
If you’re an owner, do yourself a big favour. Dig the well before your thirsty. Get exit ready now.
