One of the easiest and most effective ways to determine the true market value of any second-hand item is by conducting a search on eBay. This method provides a real-time snapshot of what similar items are currently listed for and, more importantly, what they have actually sold for.

To get started, search for an item similar to yours, such as a black leather sofa, and use the filters on the left-hand side to refine the results by selecting "Used", "Leather", and "Black". This will show a mix of Buy It Now listings and ongoing auctions. However, keep in mind that the prices listed in Buy It Now ads are just what sellers are hoping to get, not necessarily what the items are worth. For example, I could list a signed photo of myself for £500, but that doesn’t mean anyone would actually buy it! Just because someone is asking £200 for an item similar to yours, it doesn’t mean it will sell for that price.

To find a realistic valuation, scroll down to the "Sold Listings" link on the left-hand side of the search page. Clicking this will show completed sales, giving you an accurate idea of what people have actually paid for similar items over the past few weeks or months. To estimate the value of your item, take an average price from at least 10 similar sold listings, keeping in mind age and condition.

Keep in mind that these prices reflect sales to the general public, a second-hand dealer would typically pay only around 30% of this value. This is because they must account for collection, storage, resale, and delivery costs before even considering a profit. Understanding these factors can help you set realistic expectations when selling second-hand furniture and household items.
