With a few exceptions, furniture loses value quickly after you purchase it. Potential buyers of used furniture know that any given used couch could have been slept on, sweated on, been a home to cats and other abuses. When pricing your furniture, the first thing to keep in mind is that even if the furniture is in pristine condition, you're most likely not going to get what you paid for it. If you want to sell your used furniture you need to price it in a way that will encourage a sale.
Price the item at approximately half of what you paid for it. This is the golden rule of selling used furniture, unless you have a rare antique. This price will increase or decrease slightly depending on other pertinent factors about the item, such as construction, materials used, age and style.
Evaluate the condition of the piece of furniture in question. Search the items for nicks, chips, stains, loose threads, holes, tears, scratches and other things that could lessen it's value. If the item has a great many flaws, knock another 25 per cent to 50 per cent off the price, depending upon the severity of the imperfections.
Evaluate the uniqueness of the item. If the piece of furniture has some unique features--fixtures, fabric, colour or style--that add to its desirability. Likewise, if the style of the item is incredibly hot or popular at the given time, mark up the price by 25 per cent to 50 per cent of the starting price, depending on how desirable you feel the item is.
Evaluate the item's size. Massive pieces of furniture that require people to rent trucks or vans to haul them away or unwieldy items that don't fit into small houses or apartments are simply more difficult to sell. If you are trying to sell a piece of furniture this big, mark the price down 25 per cent to 50 per cent. A big price cut for a large item will motivate people to figure out a way to take it home.
