租赁关系对不动产交易(抵押权的实现)和抵押权的设立的成败有着关键性的影响。时下,本为保护弱势者平衡社会利益而产生的买卖不破租赁制度被恶意滥用以致阻碍不动产的流通,损害抵押权人的利益。是否仅凭租赁合同产生对抗效力就可以阻碍不动产的流通,这一问题足以引起我们的反思。 Lease relationship has a crucial impact on the real estate transaction (the realization of the mortgage right) and the success or failure of the establishment of the mortgage. Nowadays, the unscrupulous sale and purchase system created to balance social interests for the protection of the underprivileged has been maliciously abused to impede the circulation of real estate and undermine the interests of the mortgagee. The question of whether or not a lease contract can only create a countervailing power can hinder the circulation of real estate is enough to arouse our reflection.
