There's a saying in the real estate trade: "Fair market value is the price a buyer is willing to pay."
Just as you did when you set your asking price, buyers will take into account comparable properties, the market climate and how urgently you need to sell before they make a bid.
If you live in a market where prices are rising, you can probably look forward to a higher bid-and possibly competing bids-than if you live in a softer market.
You and your buyer will negotiate to get the best market value for yourselves-and it starts with an offer to purchase from the buyer.
