Currently, there are many clients in the market who fixed their interest rates three or five years ago, as these fixation periods make up more than 70% of all mortgages in our country. These clients have to consider now for how long they should fix their rate for the following interest season. They are re-entering the mortgage market, and besides choosing another period for their fixed interest rate, there are also a lot of them giving serious thought to the possibility of refinancing through another bank. The moment of the expiration of the fixed interest rate is the only chance to replace the debt without paying significant penalties or pre-payment fees charged by the bank. There is quite a big difference in interest rates amongst local mortgage banks, in some places reaching up to 1% p.a. Then the total savings of the refinancing may be really significant due to the rate difference and also thanks to possible optimizing of other loan parameters (mortgage maturity, loan-to-value, rate fixation period, regular fees, etc.)
