自住房一个，2009年底购入第2栋房，2010年2月开始出租，直到 2010年12月底， 现在在报2010的税， 有以下问题：for my understanding, since the second house had rent out for 11 months, I can use form 4562 for depreciation and carry the profit/loss to Schedule A, my question is: for the first month of 2010, which the second house was vacancy, can I still deduct its montgage interest and property tax on my 1040 Schedule A(加上我自住房的interest and Property tax, right?), how much I can deduct, is it ONLY for January 2010, which is 1 month? Also, 如果今年2011年我不再出租这套房，明年报税时，是不是很简单的把两个房子的 montgage interest and property tax 都加在Schedule A 里就好了？？
谢谢。
