It might go without saying, but it is important to have all of the details of your real estate contract written down at the time of agreement. I have seen many people who had a verbal agreement that the sellers would leave a particular item, but it wasn’t in the written agreement and so there are limited options if the seller takes that item (or doesn’t do the repair, etc.). When you receive an offer or counter-offer, either accept it, reject it, or counter – clearly, in writing.
