Fixed interest rate If you're looking for stability and assurance, a fixed interest rate allows you to maintain the same monthly payment throughout the entirety of your mortgage or throughout the period defined. You'll always know what amount you will pay, as you won't be dependent on the fluctuations of the market. Variable interest rate A variable interest rate could have the benefit of having an initial monthly payment that's less than the fixed rate, depending on the offer of each Bank. By choosing this interest rate, you know that your monthly payment will vary throughout the length of your mortgage, according to the indexed. Available on the market is the Euribor (Euro Interbank Offered Rate) at 3 months, 6 months or 12 months, meaning that at the periodicity of the chosen indexed your monthly payment is reevaluated and may at times be decreased or increased. Mixed interest rate A mixed interest rate allows you to start your loan with a fixed interest rate (depending on the offer of each Bank, it's possible to fix your rate for 2, 3, 4, 5, 10, 15, 20, 25 or 30 years) in which you'll always pay the same monthly payment amount for that time period, and afterward your loan will be indexed at the variable interest rate. In this case, your monthly payment will be revisited for the remaining length of your loan, and increased or decreased based on the rates being practiced in the market at that time.
