Should the mortgage property certificate be red or green?

The color of the real estate license depends on the nature of your house. If the house is a commercial house, it is red. The real estate license of this color can be bought and sold freely. As for the green one, it belongs to the homestead. Homestead is not a commercial house. Because it is self-built, the local tax has not been paid after the house is completed and licensed. Therefore, this certificate cannot be traded freely, and the Housing Authority does not recognize this certificate as a valid certificate for trading.
