Well yes I know what a collateral means but in this case on this forum, because i may be wrong, but collateral is taken when you fail to repay your loan, right? and returned to you if you do, yeah?
Some reasons you must know about that, There is the payback date about your loan.
The simple answer if you pay it in the outside of due date about your loan, and lenders will be able to take your collateral as your compensation.
The main thing about the payback date for your loans.
If the lenders give a remission for you and you will be able to take back your collateral as you can pay a fine for them.
But all of it depends on the loan agreement.
You must read them before asking a loan for yourself.
