请柠檬和有经验的给把关这个closing statement

 有个房客三代在一个房子里住了四年。今年靠工伤死去亲人的赔赏金买了房子搬出去。感觉西裔的第二代比第一代难打交道很多。这个第二代是专业PM，好在我平时也是一切按规矩办事，四年相安无大事。可是他们搬走房子搞得很脏，我看在他们住了四年的份上也没打算跟他们争执清洁费。可是walk through 时，他们坚决不同意付任何damage，说不是他们搞坏的，还威胁任何扣任何押金就去法庭。你们看照片这是正常磨损吗？我不想搞得法庭去，但也不想让他们太嚣张。所以不想给他们一项一项Argue的机会，　就把total number减了５０％。　请大家看看下面statement有漏洞吗？
