Home Refinancing: Is It Really Worth the Switch?

For those paying off a mortgage, "Refinancing" is a term you often hear after a few years. Typically, after the initial 3-year promotional low-interest period ends, the interest rate shifts to a higher floating rate (like MRR). This means your monthly payments contribute less to the principal and more towards interest. Refinancing offers a crucial way out.

What is Home Refinancing?

Home refinancing means taking out a new loan from a different financial institution (or securing a new loan package from your current bank, often called "Retention") to pay off your existing mortgage. The primary goal is to reduce your interest rate. It can also be used to extend the loan term, thereby lowering your monthly payments and increasing your financial liquidity.

Things to Consider Before Refinancing

While refinancing might offer a lower interest rate, it’s not always a guaranteed money-saver because moving your loan often incurs "hidden costs" (Refinance Costs), such as:

• New Mortgage Registration Fee: Typically 1% of the loan amount (though some banks offer promotions to waive this).
• Appraisal Fee: Around 2,000 - 3,000 THB, depending on the bank.
• Stamp Duty: 0.05% of the loan amount, capped at 10,000 THB.
• Fire Insurance: You may need to purchase a new policy.

How to Calculate If It's Worth It

The simple rule for deciding whether to switch banks is comparing the "interest saved" against the "refinancing costs." The calculator above helps you find the "Break-even Point." This refers to the number of months you need to stay with the new loan for the monthly savings to cover the upfront costs you paid to switch.

For example, if your refinancing costs are 30,000 THB but you save 2,000 THB a month on payments, your break-even point is 15 months (30,000 ÷ 2,000). This means that after the 15th month, you actually start profiting from the savings. If you plan to sell the house before 15 months, refinancing wouldn't be a wise choice.

Don't forget to ask your current bank about loan retention (lowering your current rate) before making a move. Retention saves you the hefty 1% mortgage registration fee and other hassles. Even if the offered rate isn't as low as a competitor's, the overall cost savings might make it the better and more convenient option.
