緊急求助，先謝謝了 ！！！

女兒在紐約上學，在曼哈頓租了一個單間（房租）1200刀，當時是month to month lease，房東口頭上說可長期租，兩年之內不漲價，我女兒也買了一點家具了。現在剛住了兩個月，房東說，她媽媽（原來住三樓）腿摔壞了，要搬到樓下來，給了兩方案：

1. You can vacate within 30 days.

2. You can move in to the one bedroom apartment upstairs (the bookshelves in the living room have to stay though, since I wouldn't have enough time to take them out. The apartment is mostly furnished and of course, has a kitchen.) If you chose this option, I can keep the $1,200 rent for an additional two months until you either find a place or chose to rent the one bedroom for $1,650 per month

請問我女兒一定的搬走 嗎 ？或付1650到租樓上的嗎？
