1. Commercial loan for pre-marital house purchase: pre-marital house purchase is purchased with commercial loan, and the property right of the house belongs to the buyer himself. However, if the house is purchased during the marriage relationship, then in some cases, the house may be regarded as the property of husband and wife. The specific situation needs to be determined according to the local marriage law and property laws and regulations.
2. Business turns to public after marriage: If the house is bought with a commercial loan before marriage and converted into a provident fund loan after marriage, the property right of the house remains unchanged and still belongs to the buyer himself.
3. Wife has a suite before marriage: If your wife already owns a house before marriage, then she has complete property rights to the house. During the marriage, if she chooses to sell the house, then according to the relevant local laws and regulations, she may need to negotiate with you and sign a joint property agreement to ensure that your interests are protected.
In a word, according to the information you provided, the situation you described is complicated, and it is necessary to analyze the local marriage law and property law to determine the relevant rights and responsibilities. I suggest you consult your local lawyer or real estate agent for more detailed and accurate information.
