The price of buying out a novel depended on many factors, such as the popularity of the novel, the publishing company, and the sales channels. Usually, the price of buying out a novel ranged from hundreds to thousands of dollars. In some cases, the novel may face copyright protection issues, and the purchase price may be higher. For example, if a novel is published by multiple editors and is widely circulated in the market, its copyright may be purchased by multiple editors, which may lead to an increase in the purchase price. The price of buying out the novel could also be affected by the sales channel. In some sales channels, such as online bookstores or physical bookstores, the purchase price of novels may be different. In addition, if the novel was adapted into a movie or TV series, the price might also increase. In short, the price of buying out a novel depended on many factors and needed to be determined according to the actual situation.
