Hello, I'm a real estate agent in Jia Lian. If you buy and sell tripartite houses through an intermediary, you can contact the intermediary to resolve the dispute. If you transfer the ownership yourself, you can go to a law firm for help. According to my professional knowledge. The benchmark interest rate of commercial loans for 27 years is 7.05%, and there are only two cases of floating 15%. One is the second suite, and the other is the mortgage consumer loan instead of the formal mortgage. However, mortgage consumer loans can only be applied for 10 years at most. Since you have applied for 27 years, it must be two sets. Maybe there is something wrong with the qualification examination, such as a controversial property in your name, or other properties in your husband's name, and so on.
