Here are some key points that may help you write your application:
1. Applicant information: Basic information such as name and contact information, as well as house-related information such as house address and auction time are required.
2. Reasons for application: You need to clearly put forward your reasons for objection, such as the appraiser's improper valuation and the actual value of the house being higher than the assessed value. You need to provide relevant evidence to support your point of view, such as market research data, housing evaluation report, etc.
3. Application requirements: You need to clearly put forward your application requirements, such as asking the court to reassess the value of the house and asking the court to cancel the auction.
4. Supplementary evidence: You can provide supplementary evidence to support your point of view, such as relevant laws and regulations and similar cases.
5. Application Form: You can write the application form in a fixed format, such as letterhead, recipient, body, ending, etc.
It should be noted that the application should be concise and logical, and attention should be paid to the accuracy and appropriateness of language expression. If you need more specific help, I suggest you consult a lawyer or a legal professional.
