When you've received an offer or multiple offers, you need to evaluate them to see if they are good offers or which is the best. The highest purchase price isn't the only thing to consider in choosing the best offer. You also need to consider the strength of the buyer's financing and the contingencies the buyer wants. You can either accept or reject an offer or make a counteroffer. In your counteroffer you can change the offer, purchase price, contingencies, or the time for completing the purchase.

It is always a good idea to accept an offer in writing binds so both you and the buyer are in a legal contract on the terms of the offer. The buyer can do the same by accepting a counteroffer in writing. Definitely be sure to be careful about what you put in writing.
