No matter what happens to the property with moldy exterior walls.

Legal analysis: you can refuse to pay the property fee, but you should discuss it according to the situation. In the first case, if the owner refuses to pay the management fee on the grounds that there are some defects in the property management service, such as the dirty environment of the community, some facilities not being repaired in time, and complaints that the owner has not handled it as soon as possible, the court will not support it. The reason is that the property service company provides property services for many aspects of the community, including the maintenance and management of the used parts of the house, the use of facilities, public order and public sanitation. As a property management company, their services are public and holistic, serving the property of the whole community. The failure of individual owners to pay property management fees on time will adversely affect the overall service of the community, which is not conducive to the timely implementation of other services. In the second case, the realty service enterprise fails to perform its obligations during the performance of the contract, and the service items and quality provided are obviously different from the legal or contractual standards. When dealing with such cases, it is generally considered to judge the property service enterprise to bear the liability for breach of contract. In the specific way of bearing the liability for breach of contract, the amount of property management fee can be reduced according to the owner's demands to balance the interests of both parties.

Legal basis: Article 577 of the Civil Code of People's Republic of China (PRC). If one party fails to perform its contractual obligations or fails to meet the contract obligations, it shall bear the liabilities for breach of contract such as continuing to perform, taking remedial measures or compensating for losses.
