I agreed to sell my car to an individual for $24650. After that the person paid $99 for an Auto Inspection. After the inspection the person wanted to reduce the price to $24000. I suggested $24500 and the person went back down to $24200. I needed to make a quick decision so the next morning I said okay. About 3 hours later I backed out of the deal because I thought the price was too low. The person now wants me to pay for the $99 inspection since I backed out. Am I legally obligated to pay ?
