Pawn real estate, pawn shops will generally require guarantees in two cases.
First, if the pawnshop is worried that you can't redeem it in the future, it will ask you to find a person with financial ability to sign a joint liability guarantee, which means that if you can't redeem it in the future, the guarantor will redeem it. This responsibility is the greatest and legally unchangeable.
Second, when your loan amount exceeds 50% of the market value of your property, and you have no other property, the pawnshop will ask you to sign a guarantee agreement. The main content of this agreement is that when you are unable to repay the loan of the pawnshop, the pawnshop will execute it through the court and auction the mortgaged property as the principal and interest of the pawnshop. The guarantor's obligation is to be able to take you to his home or borrow your property.
