Two mortgage prerequisites:

1. Collateral has secured amount. If the borrower's first mortgage loan amount has reached 70% and can only mortgage 30%, then it is naturally impossible to apply for two mortgage; If the borrower only borrows 30% of the initial mortgage amount and 60% to 70% can be mortgaged, he can usually apply for a second mortgage.

2. All procedures for the borrower to own the collateral. If the house is mortgaged, then the borrower must have the house property certificate. No real estate license can not be used as a secondary mortgage.
