关于军方房客要提前终止条约- not because of relocation

以下是我从military租户处收到的电子邮件。 他原计划在这里待3年，并于去年7月和我们签订了3年的租赁协议。 今天他突然发了邮件给我.他得到了军方的提升，并将留在我们的城市更长时间。 所以在同一个小区买了房子. 告知他将于9月15日搬出去。我有几个问题。

1.在这种情况下，他是否可以终止租赁合同基于military orders

2.如果没有，我可以向他收取租金损失，以及租赁中间更换租户的费用.清洁费用等吗?

3．我是否可以适当收取我个人花在 寻找新房客的时间的费用。 如果可以，$20-30/hour

4, 当我找到新房客的时候，我是否可以要求比我现在更高的房租（我给他租金低于市场价格是因为他签了三年租约）

我今天就把房子放入市场.可他们一直等到房子买下来才通知我,错过了最好的找房客时间. 

 I recently received a promotion in the Army that will increase my assignment time in Naperville. My initial assignment was for three years; my new assignment will now be for five. My wife and I have had some discussion on how to move forward with our housing situation and we came to the conclusion it no longer make finical sense for our family to rent for such a long time. There is an opportunity to purchase a home in steeple run and we have decided to do so. We recently made an offer to purchase a home and it was accepted. 
 

Christy and I both understand the situation this puts you in knowing we had agreed to a long-term lease. Hopefully, you understand that we made this decision based on what is best for our family. Also, we understand that we will lose our security deposit for breaking the lease. 

 

Of course, we will work with you to support showing the house as we move out. We will be out of the house on the 14 of September, the last day of our current rent period. We will keep you posted on any changes and if we will be out sooner.

 

We thank you for the opportunity to rent your home. We did not come to this decision lightly and do apologize for putting you in this situation. 

 

Thanks for understanding,

 

John
