Seller’s Use of Specific Performance

The remedy of specific performance is also available to sellers in many cases. A buyer may not want to go through with a sale and try to back out. However, some states allow the seller of real property to file a lawsuit against the buyer for specific performance. This remedy is permitted so that there is symmetry between the remedies available to buyers and sellers. However, this remedy is not available in all jurisdictions, such as in areas where the state believes that money damages are adequate to compensate the seller.

最终结果如何，看法官判决，，如那个作者说的，lucky的话，一般来说法官可能会close房屋买卖合同，只判卖方收回买主的订金，不再强迫买主买房。
