What is Home Loan Refinancing?

Put simply, to refinance is to replace your existing property loan with a new one. This is usually done when the new housing loan offers more favourable terms. 

For example, you may refinance your HDB housing loan (e.g. 2.6%) to a bank loan which offers a lower interest rate (e.g. 1.5%). Read more about refinancing your HDB loan here: How to Refinance from HDB Housing Loan to Bank Loan

You may also choose to move from one bank to another bank once your lock-in period is over and your existing plan’s interest rate goes up.  

Refinancing vs repricing

Often confused with refinancing, repricing is when you switch to a new home loan package, but with the same bank. Read more about the key differences here: Should you reprice or refinance?


How Does Refinancing Work?

How refinancing works is that when your application for a refinance property loan with Bank B is approved, Bank B will proceed to pay off your existing mortgage with Bank A, and bring over the prior loan balance. 

For example…

Say, in 2017 you took a property loan with Bank A at 1.8% (3-year fixed rate). Now that the three years is over, the rates have gone up to over 2%. At this point, you still owe Bank A $300,000. 

Thinking that this is too expensive to service the rest of your debt, you decide to shop around and found that Bank B is offering interest rates of 1.5% (3-year fixed rate). Hence, you decide to apply to refinance to Bank B. 

If your refinancing application is approved, Bank B will pay Bank A the $300,000 that you owe. You will no longer owe Bank A any money; instead, you will owe Bank B $300,000 under the terms of the new loan. The loan is essentially ‘transferred’ to Bank B.

When should you refinance your home loan?

Typically, homeowners refinance in order to lower their monthly repayments and/or interest costs by taking advantage of lower interest rates and/or shortening their housing loan tenure. Those with private properties also sometimes refinance to to take a home equity loan (also known as cash-out refinancing)

You can work out whether it makes sense to refinance by calculating your potential savings. Based on the above-mentioned example…


Existing Home Loan
(Without Refinancing)

New Home Loan
(After Refinancing)

Amount owed



Interest rate 



Monthly repayments (assuming 25-year tenure) 




$71.75 per month 

Savings after three years 

$2,583 after 36 months 

As you can see, in this case, refinancing will save you a significant sum. Assuming a 25-year tenure, if you do not refinance, you can expect to pay $1,271.56 per month when Bank A’s interest rates rise. If you do refinance to Bank B at 1.5%, you will only need to pay $1,199.81 monthly. That’s $71.75 less per month, and $2,583 saved after three years! 

Of course, this is a very simplistic illustration, and the actual amount saved will depend on things like your outstanding balance, preferred tenure, etc. You’ll also need to factor in refinancing costs, such as legal and valuation fees… Which bring us to our next point. 


Do You Need to Pay to Refinance?

Yes, there are certain costs involved with refinancing your home loan. The two main fees are 1) legal fees and 2) valuation fee. Added up, these can cost from $2,000 to $3,000+. However, many times, banks will offer to subsidize these costs to incentivise homeowners to refinance.

For example, if you’re refinancing from Bank A to Bank B, Bank B may offer you a $2,000 subsidy to help lower the costs. Subsidies often come with a clawback clause though, which stipulate that you can’t refinance again for a few years (unless you pay back the subsidy). 

Depending on the terms of your existing home loan, there may also be other costs like prepayment penalties and/or cancellation fees. To be sure, it is best to check with your current bank whether these charges will apply should you decide to refinance. 

So… Given the costs involved, should you still consider refinancing?


Is it Good or Bad to Refinance your Home Loan?

This is a tricky question as it largely depends on your unique situation, but generally, you can calculate your potential savings (as above) to help you decide if you should refinance. Factor in both your costs of refinancing and how much you can expect to save in monthly repayments.

Again, using the same example…

  • Expected refinancing cost:
    $1,500 legal fee + $300 valuation fee = $1,800 
  • Bank B’s subsidy: $2,000
  • Expected savings after three years: $2,583 – $1,800 + $2,000 = $2,783

As illustrated above, there are many instances when refinancing your loan can result in significant savings. Generally, those with HDB loans consider refinancing after a few years when they’ve paid off at least 25% of their property’s price (because most people can only borrow up to 75% from banks). Those with bank loans typically explore refinancing once their lock-in periods are over (so they can switch to another bank without having to pay any penalties).
