Good article. I learned that it's important to set a realistic price.

"It can be hard to detach from your perceived value of something," Barnes says. "Craigslist is full of oak dining sets from 1980 whose worth has apparently not depreciated at all." To get over this, look up comparable items that were listed.

Same goes for eBay. Mitzi adds, "Just go under the 'Advanced' tab next to the search bar and enter your search there, and click the 'Show sold listings' box."
