1. Negotiate with the developer: You can negotiate with the developer and ask him to apply for the real estate license as soon as possible. If the developer refuses or cannot solve the problem, you can take other measures.
2. Consult relevant departments: You can consult the local real estate management department or real estate trading center to learn about relevant laws, regulations and policies and how to deal with such problems.
3. Seek legal aid: If the problem cannot be solved through consultation or negotiation, you can seek legal aid, bring a lawsuit to the court and ask the developer to handle the real estate license.
