羊年喜庆期间活动一下脑袋：各位邦忙分析一下这楼卖的原因

刚出来的mix use 8units. One store vacant 1 store and 6apts all rented.
Asking price: $499K
but. Tax assessment is $794K
gross of income is $77,400 a year, the expenses is $27,741 so the net is $49,695 a year. 

Why is the selling price so low?

我知道那地方0K区，价格有点Off朋友想买我解答不了这问题所以请教各位。
