Legal analysis: there is no clear legal provision on how long to buy a house after divorce. When to buy a house is a personal right. If it is a fake divorce to buy a house, it is better to remarry after buying a house for one year, but now the bank will strictly check the mortgage applicants who have been divorced for less than half a year. If you don't meet the loan application qualification before divorce, even if you divorce, you will stop lending directly.

Legal basis: Article 10 of the Regulations on Marriage Registration, if a mainland resident divorces voluntarily, both men and women should register for divorce at the marriage registration office where one of the permanent residences is located. China citizens and foreigners voluntarily divorce in China Mainland, while mainland residents and Hong Kong residents, Macao residents, Taiwan Province residents and overseas Chinese voluntarily divorce in China Mainland. Both men and women should register for divorce at the marriage registration office where the permanent residence of mainland residents is located.
