Why can't Shenmu Xincun house get the real estate license?

The reason of the house itself, the reason of the buyers.

1. The house has no legal title certificate, the land use of the house has been changed privately, and the house or land is not mortgaged.

2. The buyer fails to pay relevant taxes, the buyer fails to provide relevant information and identification required by the house registration and certification authority, and the buyer entrusts others to handle the real estate license but fails to issue a power of attorney.
