Choosing the Right Mortgage Structure for Your Home Purchase
Selecting the right mortgage structure is a significant decision that requires careful consideration.
There are various factors that you should look at before locking in your loan structure and we look at a number here that can help. We start with a few tips for making that decision and this is more about things that you should consider.
We also explain the difference between a mortgage and the home loans and highlight a few of the key terms that you might have heard. These are explained very briefly as we often find that people have never been made aware and therefore can make mistakes in how the loans get structured.
Then we look at the different types of loans, the pro’s and con’s and why different loan types cater to varying financial situations.
Tips for Making the Final Decision
Can you pay extra on your loans?
When choosing a mortgage, remember that most of the repayment will be interest, especially in the early years.
Every extra dollar paid towards your loan helps reduce this interest burden and accelerates debt repayment. If you consider a loan of $500,000 at 4.50% over 30-years, the monthly repayment is approx $2,535 and of that $1,875 is the interest that you are paying, meaning just $660 is actually going to paying the principal of the loan. If you were able to round up the repayment to $3,000 (pay about an extra $100 per week / $465 per month) then all of that goes to paying the loan off faster. As you can see below, that will shave over 8-years off the loan term and save you over $125,000.

Understanding what your loan allows in terms of flexibility and additional payments is crucial. As illustrated you want to be able to pay extra, but you also want to retain the flexibility and not ever be forced into repayments that are too high for you.
Make sure that you have flexibility
Flexibility is key, as life is unpredictable.
Your loan structure should offer you some control allowing you to adjust to changes in your financial situation. It’s common to see people that have not considered this and have believed that the bank will be there to assist as circumstances change; however finding out that the bank is not able to help when needed. Prudent planning would suggest that you structure your lending so that you retain the maximum control yourself.
Are you good with money?
Being honest about your money management skills is also vital. Not everyone excels in this area, and your loan structure should reflect your capabilities and financial habits. Of course you might believe that you can improve, but we’ve seen too many Kiwis that think they will be okay only to admit years later that they were not that good with managing money and unfortunately by then it had cost them a lot of money.
You should structure your lending to match your situation and money management, knowing that if you have the right lending structures you can amend that later as your situation and skills change.
Do you anticipate any changes?
Consider any future changes that might impact your finances, both positively and negatively.
Anticipating increased income, such as bonuses or inheritances, can influence your loan choice. Conversely, potential reductions in income, job changes, or major life events like starting a family should also factor into your decision.
Splitting your mortgage into multiple loans
This can reduce risk, much like diversifying investments.
Ensuring that not all fixed rates expire simultaneously can provide financial stability and flexibility.
Keep regular contact with your mortgage adviser
Staying engaged with your mortgage adviser ensures you receive ongoing advice, helping you navigate changes and make informed decisions about your loans and of course paying off your home loan faster.
Understanding the Basics of Home Loans
The world of home loans can seem like a labyrinth of terminology and options.
To navigate this effectively, and to save making mistakes you must first grasp the basic concepts and definitions that underpin mortgages.
What is a Mortgage?
A mortgage is more than just a loan; it is a legal contract between you and a lender, typically a bank or financial institution.
This agreement involves borrowing a substantial sum of money to purchase property, with the property itself serving as security for the loan. The lender provides the funds, and you agree to repay the loan over an agreed period, often spanning decades. This long-term commitment requires careful consideration and planning.
While people often use the terms “mortgage” and “home loan” interchangeably, they are not entirely the same.
The mortgage is the security instrument that ties the property to the lender, while the home loan details the funds provided and the terms of repayment. There can be multiple loans secured by a single mortgage, each with specific conditions and repayment schedules. Understanding this distinction helps clarify the financial obligations and the lender’s rights if repayment issues arise.
Some Key Terms:
Diving into the mortgage world means acquainting yourself with some key terms.
Home loans are the actual loans secured by the property through a mortgage.
The home loan interest rate is a crucial component as that dictates the cost of borrowing. Your principal is the original sum borrowed, while the interest is the cost to you for using the lender’s money.
A pivotal term in this landscape is the loan-to-value ratio (LVR). This ratio measures the loan amount against the property’s purchase price or valuation. In many markets, including New Zealand, loans with an LVR exceeding 80% are considered higher-risk, often incurring an additional low equity margin (LEM). This extra charge compensates the lender for the increased risk of default.
Understanding these terms empowers you to evaluate different loan offerings critically.
Why Understanding Different Types of Mortgages Matters
Choosing the right mortgage isn’t a one-size-fits-all decision.
Different loan types cater to varying financial situations, and comprehending these differences is key to making informed choices. Whether you’re a first-time homebuyer or a seasoned property investor, understanding your options can provide the flexibility you need to adapt to changing circumstances and ultimately save you money over the lifetime of your loan.
Professional advice can be invaluable in navigating this complex landscape and that’s why businesses like Mortgage Managers exist.
Financial circumstances, investment properties, and personal goals all play a role in determining the most suitable mortgage structure. By arming yourself with knowledge, you can tailor your approach to align with your financial situation and long-term objectives, potentially paying off your mortgage faster.
Floating Rate Loans: Flexibility and Risk
Floating rate loans can be an enticing option for those seeking financial flexibility. However, they come with their own set of challenges.
Understanding Floating Rate Loans
Floating rate loans are characterised by interest rates that fluctuate over time. Lenders adjust these rates in response to changes in the broader financial market. Unlike fixed-rate loans, your monthly repayments can rise or fall, reflecting these interest rate shifts. This variability allows you to increase repayments or make lump-sum payments without incurring penalties, offering a degree of freedom not typically found in fixed-term loans.
The key to understanding floating rate loans lies in the concept of the daily loan balance. Interest is calculated daily, which means regular payments can significantly impact the total interest paid over time. However, the unpredictability of interest rate changes can make budgeting challenging, especially if rates rise unexpectedly.
Benefits of Floating Rate Loans
One of the standout benefits of floating rate loans is their flexibility. This type of loan accommodates increased or lump-sum repayments, allowing you to pay off your loan faster if your financial situation permits. This flexibility can be especially appealing if you’re in a position to make larger repayments or anticipate receiving a windfall, such as a bonus or inheritance.
For some, the initial repayments on a floating rate loan may be lower than those of a fixed-rate loan. This can free up funds for other expenses or investments, providing additional financial breathing room. However, it’s essential to weigh these benefits against the potential risks associated with fluctuating rates.
Risks Involved with Floating Rate Loans
While flexibility is a major draw, floating rate loans come with inherent risks. Chief among these is the potential for rising interest rates, which can lead to higher repayments and financial strain. If rates increase significantly, borrowers may find it difficult to maintain their current financial commitments or adjust their budget accordingly.
For those with irregular income or a tight financial situation, the unpredictability of floating rates can pose substantial challenges. Planning for future expenses becomes more complex when you can’t predict your monthly repayment amount. Therefore, it’s crucial to assess your financial resilience and risk tolerance before opting for a floating rate loan.
Fixed-Rate Loans: Stability and Predictability
For many borrowers, fixed-rate loans offer a sense of stability that is hard to ignore. Here’s what you need to know about this popular mortgage option.
How Fixed-Rate Loans Work
A fixed-rate loan locks in your interest rate for a specified period, usually ranging from one to five years. During this time, your monthly repayments remain constant, unaffected by fluctuations in the financial markets. This predictability is a significant advantage, as it allows you to plan your finances with greater certainty.
Each repayment consists of a portion of the principal and the interest due. Over time, the proportion of your payment allocated to the principal increases, while the interest portion decreases. This amortisation process ensures that your total loan balance gradually reduces over the loan term, providing a clear path to debt-free homeownership.
Advantages of Fixed-Rate Loans
The primary advantage of fixed-rate loans lies in their stability. With no surprises or sudden changes in repayment amounts, you can budget with confidence and focus on other financial goals. This predictability is particularly beneficial for households with fixed incomes or those who prefer long-term financial planning.
Fixed rates also protect you from potential interest rate hikes. If market rates increase, your fixed-rate loan remains unchanged, shielding you from higher repayments. This aspect can provide peace of mind, knowing that your financial commitments are secure for the duration of the fixed period.
Potential Drawbacks of Fixed-Rate Loans
While stability is attractive, fixed-rate loans have their drawbacks. One significant limitation is their lack of flexibility. Early repayment or refinancing can incur penalties, limiting your ability to adjust your loan as circumstances change. This rigidity can be frustrating if you wish to pay off your loan early or take advantage of lower rates.
Additionally, fixed rates typically start higher than floating rates. This initial cost may deter some borrowers, especially if they anticipate a short-term financial improvement that would allow them to pay off their loan sooner.
What is a Revolving Credit Loan?
Revolving credit loans offer a different kind of flexibility, functioning more like a credit card than a traditional mortgage. With this loan type, you can withdraw funds up to a pre-set limit, paying interest only on the amount you use. This structure provides a flexible credit line that can adapt to your changing financial needs.
Interest is calculated on the daily loan balance, meaning that any repayments made reduce the interest payable and restore your available credit. Some lenders offer a reducing limit option, which gradually decreases your credit limit over time, encouraging regular repayments and reducing overall debt.
Benefits of Revolving Credit Loans
The primary benefit of revolving credit loans is their flexibility. You pay interest only on the borrowed amount, which can result in significant savings if you manage your withdrawals wisely. This flexibility can provide a financial safety net, allowing you to access funds for emergencies or unexpected expenses without the need to apply for additional loans.
Regular repayments reduce the interest cost and replenish your available credit, offering a dynamic approach to debt management. This structure can be particularly advantageous for those with irregular income or fluctuating financial needs.
Things to Watch Out for with Revolving Credit Loans
However, the easy access to credit that revolving loans provide comes with risks. The temptation to overspend can lead to a cycle of debt if not managed responsibly. Discipline is crucial to maintaining a healthy financial position and ensuring that the loan remains a benefit rather than a burden.
It’s essential to monitor your interest rate and repayment amount, as changes in your financial situation can impact your ability to manage the loan effectively. Regular reviews of your financial position and loan terms can help you stay on track and avoid potential pitfalls.
What is an Offset Loan?
Offset loans offer a unique approach to reducing interest costs by linking your mortgage to one or more savings accounts. The balances in these accounts offset your mortgage’s interest-bearing balance, reducing the interest charged and allowing more of your repayment to go towards the principal.
This setup combines the benefits of a savings account with those of a mortgage, providing a powerful tool for managing your finances and accelerating loan repayment.
What Makes Offset Loans Unique?
Offset loans stand out because they integrate your savings and mortgage accounts, allowing you to benefit from financial gains as your savings grow. This structure offers flexibility, as you can access your savings when needed without affecting your mortgage terms.
Multiple accounts can contribute to the offset, including those of extended family members, such as parents. This feature maximises your ability to reduce interest costs and increase the principal component of your repayments, making offset loans a versatile option for many borrowers.
Advantages of Offset Loans
The key advantage of offset loans is their ability to reduce interest costs and accelerate loan repayment. By offsetting your mortgage with savings, you can enjoy significant savings on interest charges, allowing more of your regular repayments to go towards reducing the principal.
Moreover, your savings remain accessible for emergencies, holidays, or specific goals, providing financial flexibility without compromising your mortgage strategy. This balance of savings and debt repayment can simplify budgeting and enhance financial security.
Drawbacks to Consider with Offset Loans
Despite their benefits, offset loans have potential drawbacks. They often come with higher floating interest rates, meaning the savings depend on maintaining a consistent savings balance. This requirement demands discipline and careful financial management to maximise the loan’s benefits.
Additionally, changes in your financial situation or irregular income can impact your ability to maintain the necessary savings balance. It’s essential to weigh these factors against the potential advantages when considering an offset loan.
NOTE: unfortunately there are only three banks that have an Offset Account at this stage: BNZ, Kiwibank and Westpac.
