As the saying goes “It's okay to be a pig, but don't be a hog because hogs get slaughtered.” Don't get greedy. The first offer is often the best offer, and sitting on it may cause you to lose it. Buyers want to be respected and will often walk if they think they are being shopped. They want you to respect the fact that they are putting up money. If they think you don't appreciate the offer, they will not want to do a deal with you. Be grateful for every offer. If you do not like the offer, counter it.

If you receive an offer that has acceptable features but there are portions of it that you do not want to accept, you can present a counteroffer to the buyer. A counteroffer basically says, “I accept this offer with the following modifications.” Both parties sign the original offer, subject to the counteroffer, and the modifications are outlined and signed by both parties as well.
