You can stretch your financing to longer term and due to lower rates, you will ensured to pay lower IF only the rates stay low.

If there is substantial changes, you will be squeezed to pay more.

Thus, it is only you can decide whether it is worth. Furthermore, you will fork out say, RM1K - deduct EPF/SOSCO, basically you will have half of your income to go thru the month... That is if there is no changes in the rates.

Assuming the rates does go up to say 2%, your interest payment would have changes to additional RM3,600 p.a. (RM300-00) and your repayment had to change also to higher instalment to cover the changes in interest. Food for thoughts.
