Legal analysis: the housing appraisal fee adopts differential fixed rate and progressive charging rate: if the total housing price is less than 6,543,800 yuan, it will be charged at 0.42% of the total appraisal price; 1 10,000 yuan to 5 million yuan progressive billing rate is 0.3%; 0.12% of the total appraisal price from 5 million yuan to 20 million yuan; 0.06% of the total evaluation price is charged from 20 million yuan to 50 million yuan.

Second-hand housing evaluation is divided into "free evaluation" and "paid evaluation":

1. Free appraisal: In addition to real estate appraisal companies with professional qualifications, there is also a new type of online second-hand housing appraisal that has matured. Some large domestic real estate websites or comprehensive websites with real estate channels have begun to provide free evaluation for consumers, but it should be noted that the evaluation results provided by these networks have no legal effect and can only be used as reference.

2. Payment evaluation: For example, if a property buyer needs to apply for a mortgage loan, the bank can only issue the loan to the property buyer according to the evaluation report of the evaluation agency, and the evaluation of the mortgage loan needs to be conducted by an evaluation agency with professional qualifications. The evaluation results provided by such an evaluation institution have certain legal effect.

Legal basis: Article 34 of People's Republic of China (PRC) Urban Real Estate Management Law. The state practices a real estate price appraisal system. Real estate price evaluation should follow the principles of justice, fairness and openness, based on the benchmark land price, the calibrated land price and the replacement price of various houses with reference to the local market price, and be carried out in accordance with the technical standards and evaluation procedures stipulated by the state.
