One of the most common questions we receive from our clients is:

 

“When should I refinance my home loan?” 

“Can I refinance my home loan now?”

 

The answer may seem straightforward, but timing your refinancing incorrectly can potentially cost you thousands of dollars in unnecessary interest or penalties.

 

Refinancing a mortgage is not simply about waiting until your lock-in period ends and choosing the lowest rate available. It involves understanding your lock-in period, the bank’s notice requirements, the availability period of your new loan package, and your future financial plans.

 

Over the past few years, we have seen interest rates move from historical lows of below 1% to above 4%, before gradually easing again. In such an environment, understanding when to refinance has become more important than ever.

 

In this article, we’ll explain:

• When you should start refinancing.
• Whether it is possible to refinance earlier.
• What happens if you refinance too late.
• Whether refinancing during your lock-in period makes sense.
• Situations where paying a penalty may still save you money.
• How to determine the ideal refinancing strategy for your circumstances.

 

1. Start Your Refinancing Process Around 3 Months Before Your Lock-In Period Ends

As a general rule, we recommend homeowners start exploring refinancing options approximately 3 months before the expiry of their lock-in period.

 

Many borrowers mistakenly think that they can wait until the last minute to start comparing rates. Unfortunately, refinancing is not an instant process.

 

There are several steps involved before your new loan can be disbursed.

Typical Refinancing Timeline

3 months before lock-in expiry

• Start comparing home loan packages.
• Speak to us, Mortgage advisor
• Submit refinancing applications.

 

2.5 months before lock-in expiry

• Receive approval from the new bank.
• Sign the Letter of Offer.

 

2 months before lock-in expiry

• Serve redemption notice to your existing bank.

 

Lock-in expiry

• New loan is disbursed.
• Refinancing is completed.

 

Why Three Months?

The main reason is because most banks require a minimum notice period of two months before allowing you to redeem your existing mortgage.

 

In addition, refinancing applications typically require:

• Income assessment;
• Credit review;
• Property valuation;
• Legal documentation;
• Loan approval and acceptance.

 

While the process can sometimes be completed in one to two weeks, delays can occur. Starting your refinancing process three months before your lock-in expiry gives you sufficient buffer and allows you to compare packages properly without rushing your decision.

 

Waiting until the final month often limits your choices and may result in unnecessary interest costs.

 

2. Can I Refinance Earlier Than 3 Months?

The answer is yes.

 

In fact, there are situations where refinancing earlier can be advantageous.

 

For example, if interest rates are expected to rise significantly, securing a lower rate earlier may be beneficial.

 

However, there is one important factor that many homeowners overlook:

 

The Loan Availability Period

Most banks provide a loan offer validity period of approximately four months.

 

This means that once your refinancing application is approved, the new loan must usually be disbursed within four months.

 

Some banks may grant extensions beyond four months, but these are generally subject to approval and may be capped at around six months.

 

Why Does This Matter?

Let’s look at an example.

Suppose you currently have:

• Outstanding lock-in period: 6 months.
• New package: 2-year fixed rate at 1.40%.

 

If you apply too early and the bank only allows four months of availability, you may effectively lose part of your fixed-rate period.

 

Example

2-Year Fixed Package: 24 months

Lock-in expiry remaining: 6 months

Bank’s availability period: 4 months

Difference: 2 months

 

Actual fixed period remaining:

24 months – 2 months = 22 months

 

This means your loan could potentially move to the bank’s thereafter rate (floating) two months earlier than expected.

 

The thereafter rate is usually a floating package and can be substantially higher than the promotional fixed rate.

 

Therefore, while refinancing earlier can sometimes be beneficial, it should only be done after carefully evaluating the bank’s availability period and the interest rate outlook.

 

Should I Lock In My Rates Earlier?

In some situations, the answer may be yes.

 

Examples include:

• Expected interest rate hikes by central banks.
• Rapid increases in SORA.
• Withdrawal of attractive fixed-rate packages.
• Significant market uncertainty.

 

In such circumstances, locking in a favourable rate earlier could save thousands of dollars over the next few years.

 

However, this decision should always be balanced against the potential shortening of the promotional period due to the bank’s availability requirements.

 

3. What Happens If I Refinance Too Late?

Unfortunately, this is a very common situation.

 

Many homeowners only realise their lock-in period has expired after receiving a letter from the bank informing them that their interest rate has increased.

 

This happens because they have moved onto the bank’s thereafter rate.

 

What Is a Thereafter Rate?

A thereafter rate refers to the interest rate that applies after your promotional package ends.

 

Historically, these rates are often significantly higher than the market’s best refinancing packages.

 

For example:

Package	Interest Rate
Promotional Fixed Rate	1.40%
Thereafter Rate	3.25%

For a $800,000 home loan, the difference could easily amount to several hundred dollars per month.

 

Over a year, this may translate into thousands of dollars in additional interest.

Are There Any Exceptions?

Yes.

 

There are certain periods where floating rates may decline substantially and become lower than the bank’s prevailing fixed-rate packages.

 

In such situations, remaining temporarily on the thereafter rate may actually be the better option.

 

This is why there is no one-size-fits-all answer when it comes to refinancing.

 

Every homeowner’s situation should be assessed individually.

 

At FairLoan Mortgage Advisory, we constantly monitor interest rate movements and help our clients determine whether they should:

• Refinance immediately;
• Wait for better opportunities; or
• Temporarily remain on their existing package.

 

4. Can I Refinance During My Lock-In Period?

Many homeowners assume that refinancing during a lock-in period is impossible.

 

This is not true.

 

You can still refinance during your lock-in period.

 

However, there is usually a penalty. Most banks charge a 1.5% penalty on the outstanding loan amount. The question then becomes, ‘Does paying the penalty still make financial sense?’

 

In some situations, the answer is yes.

Example 1: Significant Interest Savings

Suppose:

Remaing months to end of locked in: 12months 

Outstanding Loan: $1,000,000

Existing Rate: 3.50%

New Rate: 1.40%

 

Interest savings:

3.50% – 1.40%

= 2.10% per annum

 

The annual interest savings may exceed the one-time penalty of 1.5%.

 

In such situations, refinancing early can still result in overall savings.

This is particularly true if there is still a long remaining loan tenure.

 

Example 2: Equity Term Loan for Business Purposes

Many business owners use the equity in their properties to obtain financing.

 

Suppose:

SME Loan Rate: 4.00%

Mortgage Rate: 1.40%

 

Even after paying a 1.5% breakage fee, obtaining financing at 1.40% instead of 4.00% can produce substantial long-term savings.

 

The difference becomes even more significant when large loan amounts are involved.

 

Example 3: Decoupling Strategies

Some homeowners refinance during their lock-in period because they intend to:

• Decouple ownership;
• Purchase another property;
• Restructure their finances.

 

In these situations, paying the penalty may be worthwhile if it allows the homeowner to achieve larger financial objectives.

 

The key consideration is always whether the benefits outweigh the costs.

 

There Is No Perfect Time to Refinance

Many homeowners ask us:

“Should I refinance now or wait?”

The reality is that there is rarely a perfect answer.

The ideal refinancing timing depends on several factors:

• Current interest rates;
• Future interest rate expectations;
• Remaining lock-in period;
• Outstanding loan amount;
• Future property plans;
• Cash flow objectives;
• Equity extraction requirements.

 

Every homeowner’s situation is different.

 

How We Analyse a Refinancing Case

At FairLoan Mortgage Advisory, we do not simply recommend the lowest advertised rate.

 

Instead, we perform a detailed analysis that includes:

✓ Remaining lock-in period.

✓ Cost of refinancing.

✓ Legal subsidies.

✓ Interest savings.

✓ Future property plans.

✓ Potential penalties.

✓ Equity extraction opportunities.

✓ Whether refinancing immediately or waiting would be more beneficial.

 

In many cases, the cheapest rate is not necessarily the best option.

 

Final Thoughts

As a general guideline:

 

i) Start refinancing around 3 months before your lock-in period expires.

 

ii) Consider refinancing earlier if rates are expected to rise significantly.

 

iii) Avoid waiting until after your lock-in period ends as you may be exposed to expensive thereafter rates.

 

iv) Refinancing during your lock-in period may still make financial sense if the potential savings outweigh the penalties.

 

Most importantly, every refinancing decision should be based on a proper cost-benefit analysis rather than simply chasing the lowest advertised interest rate.
