For real estate loans, there are two rates: fixed and variable, depending on the repayment period.
If the term is over 15 years, the rate is fixed: it remains unchanged throughout the repayment period.
If the term is less than or equal to 15 years, the rate is variable: it depends on changes in MMR, and the monthly payment may be revised upwards or downwards.
The rate of credit in Tunisia is calculated on the basis of the MMR (Monetary Market Rate), to which a margin is added.
The MMR in Tunisia is administered by the BCT (Central Bank of Tunisia) and set at the beginning of each month.
The margin, which represents the bank's profit, generally does not exceed 5%, and is limited by the T E G (Taux Effectif Global) provided by the BCT at the beginning of each half-year, which gives the total cost of the loan.
