关于上行压力和下行压力还是没太懂，为什么通货紧缩价格会有下行压力呢？

NO.PZ2020012201000012 问题如下 Whiof the following statements of the reestate is wrong.

C.Unexpectey low inflation will put upwarpressure on expecterentincome anproperty values. C is correct如果通胀维持在预期范围内，续租可能会带来租金收入随预期通胀上升，资产价值稳定。所以A本身正确，不入选。高于预期的通胀很可能与房地产需求高企、租金收入增长速度将快于总体通胀的预期以及房地产价格上涨同时出现。所以B本身正确，不入选。出乎意料的低通胀(或通货紧缩)将给预期的租金收入和房产价值带来下行压力而非上行压力，尤其是那些不太优质的房产，它们可能不得不大幅削减租金，以避免空置率上升。所以C错误。入选。 请问C错在哪里呀
