Land, house and gold are commonly used as collateral for a bank loan. You can also use certificate of deposit and bonds as collateral for a loan. Apart from collateral you also need solid income source to get a loan.In my experience with a bank the collateral is always the crux for taking a bank loan. Some applicants think that any kind of real estate can be a collateral for a loan. One big issue is having no property so the applicant would use the real estate of his sibling although the sibling would not sign the co-maker sheet. The best collateral for a bank loan is real estate.
