IMHO, don't let the domain expire. Keep ownership. I made the mistake of not doing that once and later decided to re-launch the web site and found that someone bought the name and wanted an outrageous sum for it. My loss. You could also consider putting up just one page with "This domain name for sale. Contact ...." if you are sure you are not going to use the name again.

Leaving the site in place means that people will see out of date information which could reflect badly on you. My own preference as somebody who might follow a link would be a positive "closed" message.

I guess the domain will expire when the time comes
Not always, some hosts will renew automatically unless you instruct them otherwise.
Do you want the content indexed indefinitely in the Internet Archive? If not you need to put something up while it's live that bans the IA Archiver bot. There are people who will re-appropriate the content of expired domains using this resource, assuming that no-one will bother to pursue them for copyright infringement.
Finally, webmasters and directory editors often appreciate being informed of dead links.
