If Qinling is a house with complete five certificates, why not let it be traded?

It is because the property is located in a prohibited development area and the property involves land issues.

1. The property is located in the prohibited development area: Qinling area is divided into several prohibited development areas, including forests, mountains and water sources. If the real estate is located in these areas, it is impossible to obtain a development and construction permit.

2. Real estate involves land issues: the land in Qinling area is very precious, and the construction and use of real estate need to obtain administrative licenses such as land use certificates. If you can't get the land use certificate, you can't do legal transactions.
