It rather depends on the path of the comet. Some comets (such as Encke's comet) return in as little as 20 years - others might not return to our solar system for centuries (Comet McNaught has an orbital period of over 92,000 years !) It's possible to see at least one comet per year if the weather conditions ar favourable.

They can be old, but not that old. If a comet was from the asteroid belt, it would take a few years for it to get here. It could have been created a VERY long time ago though.
