What is the 'amortization period'? Its impact on the monthly payment amount.

"Ah Ken, I've got my eye on a property in Tsuen Wan, 6 million, with an 80% mortgage, a 30-year loan, the monthly payment is about $18,000. But the bank said I can 'adjust the loan term,' saying it can reduce the repayment pressure. What exactly is that?"

I hear this conversation several times every month. Many prospective buyers think that a 'divided term' is some kind of mysterious mortgage product, but it is actually just a calculation concept — and it is precisely this concept that can make your monthly payments differ by several thousand dollars, directly affecting your ability to buy a house and the pressure of mortgage payments.

Today I will explain the mortgage term 'loan tenor' in the simplest way, and I will also use real cases to show you how adjusting the tenor can make your mortgage plan more flexible. Whether you are a first-time homebuyer or a homeowner looking to refinance, this article will help you.

:::tip Expert Tips The amortization period is not a bank product, but another way of referring to the 'length of the repayment period.' The longer the term, the lower the monthly payments, but the higher the total interest paid. :::

Core Concept Analysis: What Exactly Is Amortization Period?

Amortization Period = Repayment Term Length

Simply put, the loan term refers to how many years you will take to repay a mortgage loan. In the Hong Kong property market, the most common loan terms are 20 years, 25 years, or 30 years. The longer the term, the lower the monthly repayment amount, because you are "spreading" the same loan over a longer period.

For example:

• Loan amount: $5,000,000
• Interest rate: 3.5% (P-2.5%)
• Amortization period 20 years: monthly payment about $29,000
• Amortization period 30 years: monthly payment about $22,400

You will see that for the same loan, if the repayment period is extended from 20 years to 30 years, the monthly installment can be reduced to $6,600. For middle-class families with a monthly income of $50,000 to $60,000, this difference is enough to determine whether you can pass the stress test.

How does the loan term affect the monthly payment amount?

The impact of the loan term on monthly payments mainly depends on three factors:

1. Loan Principal: The more you borrow, the higher the monthly payment naturally is.
2. Mortgage Interest Rate: The higher the interest rate, the more interest you pay.
3. Repayment Term: The longer the term, the lower the monthly payment.

In the Hong Kong property market, banks generally approve different maximum repayment terms based on your age, income, and the age of the property. For example:

• Maximum age limit: 75 minus the applicant's age (some banks use 80 minus)
• Maximum property age: 75 minus the age of the property

:::highlight Insider Tip If you are 35 years old this year and buy a property that is 20 years old, the bank will take the lower of "75-35=40 years" and "75-20=55 years," that is, a maximum of 40 years. But in practice, the maximum mortgage term in Hong Kong is only 30 years, so you will end up getting a 30-year term. :::

The longer the repayment period, the higher the total interest expense

Here is a very important concept: the longer the loan term, although the monthly payments are lower, the total interest you pay in the end will be higher.

Let's go back to the previous example:

• Spread over 20 years: total interest expense is about $1.96 million
• Spread over 30 years: total interest expense is about $3.06 million

You will see that by extending the term by 10 years, the total interest will increase by $1.1 million. So spreading the term is not necessarily better the longer it is, but it should be balanced according to your financial situation and mortgage repayment ability.

Practical Case Sharing: How Spreading the Term Can Help You Get on the Property Ladder?

Case 1: First-Time Homebuyers — Using the Full Loan Term to Reduce Payment Pressure

Background:

• Buyer: Ah Ming, 32 years old, monthly income $45,000
• Property: New development in Tseung Kwan O, property price $5.5 million
• Mortgage: 90% mortgage (via mortgage insurance), loan amount $4.95 million
• Interest rate: 3.625% (H+1.3%)

Plan Comparison:

| Installment Period | Monthly Payment | Stress Test Required Monthly Income | Total Interest Paid | |------------------|----------------|-----------------------------------|-----------------| | 25 years | $25,200 | $50,400 | $2,620,000 | | 30 years | $22,600 | $45,200 | $3,190,000 |

Ah Ming's monthly income is $45,000. If spread over 25 years, the stress test requires a monthly income of $50,400, which he won't be able to pass. But if spread over 30 years, the stress test requirement drops to $45,200, and he can smoothly get on the property ladder.

:::success Expert Opinion For first-time homebuyers, I usually recommend 'using the full loan term,' because your biggest challenge is passing the stress test. Although the total interest will be higher, at least you can get on the property ladder. Later, when your income increases, you can consider early repayment or refinancing to shorten the term. :::

Case 2: Home Upgrader — Shorten the Loan Term to Reduce Interest Payments

Background:

• Buyer: Mrs. Chen, 48 years old, monthly income $80,000
• Property: Second-hand apartment in Sha Tin, property price $8,000,000
• Mortgage: 60% mortgage, loan amount $4,800,000
• Interest rate: 3.5% (P-2.5%)

Plan Comparison:

| Term | Monthly Payment | Total Interest Paid | |---------|---------|----------| | 30 years | $21,500 | $2.94 million | | 20 years | $27,900 | $1.89 million | | 15 years | $34,300 | $1.37 million |

Mrs. Chan has a stable income and ample capacity to make contributions. If she chooses to spread it over 15 years, although the monthly payments will be higher, she can save a total of $1.57 million in interest.

:::tip Insider Tip If you are someone changing homes with a stable income, I would suggest you consider shortening the mortgage term. This is because you usually already have some savings, the payment pressure is lower, and shortening the term can significantly reduce interest expenses, making it more beneficial in the long run. :::

Case 3: Investor — Flexibly Using Term Management to Manage Cash Flow

Background:

• Buyer: David, 40 years old, monthly income $100,000
• Property: Tsuen Wan rental property, property price $6,000,000
• Mortgage: 50% mortgage, loan amount $3,000,000
• Rental income: $16,000 per month

Strategy: David chose to spread over 30 years, with a monthly contribution of about $13,500. After the contribution, there is still a positive cash flow of $2,500 per month. Although the total interest will be slightly higher, he can keep more cash to invest in other properties or run a business.

:::highlight Expert Opinion For real estate investors, the choice of loan term should match your investment strategy. If you are pursuing 'paying less than renting' and positive cash flow, extending the loan term is a reasonable approach. But if you want to pay off the property faster and then use it for refinancing, then you should consider shortening the loan term. :::

Notes and Risks: Common Misunderstandings About the Distribution Period

Misconception One: The longer the term, the better?

A lot of people think that the longer the installment period, the better, because the monthly payment is smaller. But actually, this way of thinking has a flaw:

1. Total interest expenditure greatly increases: As mentioned above, a 30-year term pays $1 million more in interest than a 20-year term.
2. Mortgage term is extended: If you start paying a 30-year mortgage at 35, you will only finish at 65, by which time you are already retired and your income has significantly decreased.
3. Flexibility for refinancing decreases: The longer the term, the less principal is repaid each month, leaving less room for future refinancing or additional borrowing.

:::warning Guide to Avoiding Pitfalls Don't blindly pursue the 'longest term.' You should choose a balanced term based on your age, expected income growth, and retirement plans. Generally speaking, I would suggest that the mortgage term should not exceed the retirement age. :::

Misconception Two: Once the amortization period is set, it can't be changed?

Many people think that once the repayment term is set, you have to pay through the entire term. Actually, that's not the case! You have the following options to adjust it:

1. Early Repayment: Most banks allow you to repay up to a certain limit each year without penalty (usually 10%-20% of the loan amount).
2. Refinance to Shorten Term: If your income increases, you can refinance to shorten the term from 30 years to 20 years.
3. Additional Loan to Extend Term: If you need to cash out, you can take an additional loan to extend the term back to 30 years.

:::tip Experts recommend I usually advise clients to 'first get on the property ladder with a long-term plan, and then adjust flexibly later.' Because the most important thing when getting on the property ladder is to pass the stress test. Once you are on the property ladder, you can optimize your mortgage plan through early repayment or refinancing. :::

Misconception Three: Ignoring the Impact of Building Age on Its Lifespan

Many people look at second-hand properties, thinking that because they are young, they can definitely spread payments over 30 years. But in fact, banks consider both 'age of the person' and 'age of the building' at the same time:

• Building age under 30 years: Generally can be allocated 30 years
• Building age 30-40 years: May only be approved for 20-25 years
• Building age over 40 years: May only be approved for 15-20 years

If you buy a property that is 35 years old, the bank may only approve a 20-year loan term (75-35=40, but the actual term will be further reduced), so your monthly payments will be much higher.

:::warning Guide to Avoiding Pitfalls Before buying a second-hand property, remember to clearly ask the bank how many years of mortgage they can approve. Don’t assume that just because you are young, you can definitely get a 30-year term; the age of the property is the key. If the property is too old, you may need to consider other properties or be prepared to pay a higher down payment to reduce the loan amount. :::

Risk Four: The Impact of Rising Interest Rates on Long-Term Mortgages

The longer the amortization period, the more sensitive you are to interest rate changes. If you amortize over 30 years, and the interest rate rises from 3.5% to 4.5%, your monthly payment could increase by $2,000-$3,000.

Risk Management Recommendations:

1. Set aside a contribution buffer: Make sure your contribution-to-income ratio does not exceed 40%.
2. Consider a fixed-rate mortgage: If you are worried about interest rate hikes, consider locking in a 2-3 year fixed rate.
3. Regularly review your mortgage plan: Review it every 1-2 years to see if there are better refinancing offers.

Summary: The allocation period is a tool, not a goal

Speaking of this, I believe you already understand that 'amortization period' is actually another term for 'repayment period.' It is not some mysterious mortgage product, but a financial tool that you can use flexibly.

Key Points Review:

• The longer the term, the lower the monthly payment, but the higher the total interest
• First-time homebuyers are advised to use the full term to ensure passing the stress test
• Home upgraders or high-income earners may consider shortening the term to reduce interest expenses
• Investors should flexibly choose the term based on cash flow needs
• Don’t ignore the impact of property age on the term
• The split term is not fixed and can be adjusted later through early repayment or refinancing

Remember, the loan term is just a tool; the most important thing is to match it with your financial situation, life stage, and property goals. Buying a home is not the end, but the beginning of a financial plan. Choosing the right loan term can make your mortgage payments easier and provide better protection for your quality of life.

:::success Confidence Guarantee Whether you are a first-time homebuyer, someone looking to move to a new property, or an investor, as long as you understand how the mortgage term works and follow the advice of a professional mortgage consultant, you will definitely be able to find the most suitable mortgage plan for yourself. Although the Hong Kong property market is complex, as long as you have the correct knowledge, buying a home is actually not as difficult as you think! :::
