APR stands for annual percentage rate. Thus, your APR would be the amount of interest accrued on debt held for one year. Your APR generally consists of a combination of a base rate and the bank’s margin. Depending on your credit history and your predicted risk, the bank will collect a higher or lower margin on top of the base rate, determining your overall APR.
A lien is a type of security interest granted over property to secure payment of a debt or other obligation. This means the person who holds the lien has the right to take possession of the property with a lien on it unless you pay him or her as agreed. However, if you can make the payments owed the lien will be lifted and you will be in the clear.
