Sure you can sell it.
Options:
1) Online site markets, sitepoint.com and others have forums and tools that allow site owners to sell and either set their price or run an auction for the site. These are probably your best bet for a quick sale, though not for the highest ROI.
2) Maintain the site and let it run adsense to generate a trickle of side income. One new tutorial a week, or some sort of new content to help with SEO and user returns. The ROI on this sort of site is high, even if the total income is low, the time investment remains low.
3) Try to convert the site to include an editorial / blog to entice ad brokers. A much higher level of time investment with potential for the gains to increase as well.
3.a) To minimize your own time investment, pull a FHWW and look to hire virtual assistants to generate new content or content ideas. Will still require time editing and finding the freelancer / assistant, but can also reap benefits.
Best of luck!
