Another approach is to engage the low baller in negotiations back and forth for a few days. Then if you sell it to someone else, string them along a few more days after it’s sold and you already have someone else’s cash. Then tell them, sorry it sold three days ago, but since you’ve been wasting my time, how does it feel for you? Or if it hasn’t sold tell them that you decided to keep it, but leave the ad up until it sells.

I’m usually not, but most of these types of buyers either don’t have any real interest in buying something unless they can buy it from you half off because you’re desperate for cash, or they don’t have the cash to buy it for 90% of asking price anyways.

No you’re just educating the seller. If enough people reach out and e plain that it’s worth $2,000, maybe they’ll lower their price to a realistic number.
