1. Since your girlfriend has agreed to give up the property right of the house, you need her to write a "declaration of giving up the property right", indicating that she agrees to give up all the rights and obligations of the house (write down the address, room number, area and other details of the house clearly), and let her sign it and press her fingerprint;

2. Bring your ID card and the Declaration of Abandonment of Property Rights, and go to the law firm with her for legal justice. The law firm will issue you a notarial certificate on the division of housing property rights as an effective legal document;

3. After your loan is paid off, you can go to the Housing Authority to correct the real estate license and remove your girlfriend's name with the real estate license, the Declaration of Abandonment of Property Rights and the notarial certificate of the law firm.

Good luck!
