I have a house, which is a secured loan, that is, the house has no mortgage and the mortgage has not been paid off. Now I want to mortgage, can the bank approve it?

In theory, it can be approved, but in practice it is extremely unlikely. For example, if the value of your house is 654.38+00,000 and the guarantee amount is 500,000, then the remaining 50,000 value of your house can be used as collateral. This is from the legal level, but in practice, on the one hand, real estate mortgage is not very good in banks, and when the same mortgage involves two creditor's rights, the bank's acceptance is very low, so you must guarantee it first. If banks want to implement it, they will be behind the guarantee company to enjoy their rights. If you want to use a house loan, you should either pay off the loan from the insurance company or replace the house with other collateral. It is almost impossible to get a loan from a bank at present.
