Loan security is a mechanism for guaranteeing the repayment of a loan, which protects the rights of the creditor. A borrower can leave some tangible assets (such as a car or real estate) as security for a loan, which then becomes a secured debt to the creditor who issues the loan. Thus, the loan is secured, and if the borrower defaults, the creditor takes possession of the asset used as its security.

However, most sources state that lending agencies require a minimum credit score ranging from 580 to 620 in order to approve a VA loan. However, it should be noted that there are precedents in which people managed to get a VA loan even with a credit score of 500.

A bridge loan is an interim or auxiliary loan issued by a bank for a period of up to 1 year at a fairly high interest rate to cover the borrower's current obligations.
