Collateral: Property or other valuable assets which a borrower offers as a way to secure the loan. This is insurance for the lender if you end up defaulting on the loan. 

Home and auto loans are secured because if you default, the lender can seize the house or vehicle. 

Personal Loans

Borrowing money for any kind of personal reason.  Typically, a personal loan can be obtained for a few hundred to a few thousand dollars, with repayment periods of two to five years. This is an expensive way to get money because these loans are unsecured. Since there is significant risk to the lender, the interest rates tend to be very high. APRs for personal loans can range from 9.95% to 35.99% with an average of 10.21%. 

Mortgage

A type of loan used to purchase or maintain a home, land, or other kinds of real estate. Mortgages are secured loans and the property serves as collateral. Most mortgages are fixed rate (see interest rates), but some can be adjustable rate. 

Auto Loans

Auto loans are secured loans like mortgages because if the borrower defaults, the lender can seize the vehicle.
