You'll present an offer, through your agent, and the seller can accept it, reject it, or make a counteroffer. Price is negotiable, as is your earnest money and or closing date. You can request that window dressing, porch swings, fireplace doors, and certain appliances (washer/dryer/refrigerator) stay with the house. You can negotiate contingencies such as "contract is subject to the buyer obtaining a satisfactory house inspection." Negotiations may go back and forth, but once the seller accepts your offer, you have a legally binding contract. Contact me, your Real Estate Professional for more information.
