For purposes of this subsection (2) of this Section 46, a prepayment shall mean the payment of the total indebtedness, with the exception of late payment penalties if incurred or charged, on any date before the date specified in the contract or loan agreement on which the total indebtedness shall be paid in full, or before the date on which all payments, if timely made, shall have been made. In the event of a prepayment of the indebtedness which is made on a date after the date on which interest on the indebtedness was last computed, calculated, charged, or collected but before the next date on which interest on the indebtedness was to be calculated, computed, charged, or collected, the lender may calculate, charge and collect interest on the indebtedness for the period which elapsed between the date on which the prepayment is made and the date on which interest on the indebtedness was last computed, calculated, charged or collected at a rate equal to 1/360 of the annual rate for each day which so elapsed, which rate shall be applied to the indebtedness outstanding as of the date of prepayment. The lender shall refund to the borrower any interest charged or collected which exceeds that which the lender may charge or collect pursuant to the preceding sentence.
For purposes of this Section, "revolving credit" has the meaning defined in Section 4.1 of the Interest Act.
Any mortgage or deed of trust given to secure a revolving credit loan may, and when so expressed therein shall, secure not only the existing indebtedness but also such future advances, whether such advances are obligatory or to be made at the option of the lender, or otherwise, as are made within 20 years from the date thereof, to the same extent as if such future advances were made on the date of the execution of such mortgage or deed of trust, although there may be no advance made at the time of execution of such mortgage or other instrument, and although there may be no indebtedness outstanding at the time any advance is made. The lien of such mortgage or deed of trust, as to third persons without actual notice thereof, shall be valid as to all such indebtedness and future advances from the time said mortgage or deed of trust is filed for record in the office of the recorder of deeds or the registrar of titles of the county where the real property described therein is located. The total amount of indebtedness that may be so secured may increase or decrease from time to time, but the total unpaid balance so secured at any one time shall not exceed a maximum principal amount which must be specified in such mortgage or deed of trust, plus interest thereon, and any disbursements made for the payment of taxes, special assessments, or insurance on said real property, with interest on such disbursements.
Any such mortgage or deed of trust shall be valid and have priority over all subsequent liens and encumbrances, including statutory liens, except taxes and assessments levied on said real property.
(4-5) For purposes of this Section, "real estate" and "real property" include a manufactured home as defined in subdivision (53) of Section 9-102 of the Uniform Commercial Code which is real property as defined in Section 5-35 of the Conveyance and Encumbrance of Manufactured Homes as Real Property and Severance Act.
