Introduction to Investment Properties
Buying an investment property is one of the most popular ways Kiwis look to grow wealth and build long-term financial security. A residential investment property can provide regular rental income, potential capital gains as house prices increase, and diversification outside of your own home and investments out of the property industry.
But the key question remains: how much can I borrow to buy an investment property?
The answer depends on your financial situation, the lending criteria set by banks and lenders, and how your home loan is structured. At TAG we help borrowers understand what they can potentially borrow, how to compare investor loans, and what strategies to use when planning to buy an investment.
Assessing Your Finances
To determine how much you could borrow, start by reviewing your personal situation:
- Income and Expenses: Stable income streams (salary, self-employed income, or rental income) increase borrowing power. Outgoings like debt repayments, living expenses, and other expenses reduce it.
- Credit History: Clean repayment records on your home loan balance or existing property, and short term debts strengthen your profile.
- Savings and Cash Deposit and equity: Most lenders require a cash deposit for a new investment property, but you can also use equity in other properties you own, often 30% of the total value unless exemptions for new build properties apply.
- Cash Flow: Banks assess whether your mortgage repayments are affordable alongside property costs like insurance, rates, and maintenance.
An online mortgage calculator can give an estimate, but every borrow based calculation is tested against your actual financial situation.
Understanding Mortgage Options
There are different loan types for investment properties, including:
- Fixed-Rate Investor Loans: Provide repayment certainty but may lock you in if interest rates fall.
- Variable-Rate Loans: More flexible, but repayments can increase if rates rise.
- Interest-Only Loans: Lower initial payments to free up cash flow, but no principal is reduced, which means your repayments will be higher when your interest only period ends as your loan term will then be shorter.
- Principal and Interest Loans: Build equity faster, but require higher repayments.
Some lenders offer investment features like offset accounts and revolving credit facilities. Comparing fees, features, and conditions across banks and third-party websites can help find the right option.
Home Loan Considerations
Lenders apply different rules to a residential investment property than to an owner-occupied property:
- Loan to Value Ratio (LVR): For most, a 70% LVR applies—meaning you need at least a 3% deposit, which can be made up of cash and/or equity. A high LVR means tougher scrutiny.
- How Much Equity: If you already own property, you can use existing equity as the deposit for a new investment property – this works by borrowing against the existing property (using the equity).
- New Lending: Banks apply stress tests on interest rates above current levels to ensure you can still afford repayments if rates rise.
- Repayment History: Strong history on your current mortgage or loan supports your application.
Every lender has its own lending criteria, which is why a tailored plan is essential.
Buying Your Investment
When you know how much you can borrow, it’s time to start looking. Consider:
- Location and rental demand in the property market
- Type of property (existing or new build property)
- Potential rental income versus mortgage repayments (is it negatively geared or positively cash-flowing?)
- Ownership structure, seek accounting advice to see if setting up an LTC ot Trust to own the property is beneficial for you
- Alignment with your long-term investment goals
Do your research carefully—third-party websites and property websites with listings, yield calculators, and suburb reports are helpful starting points.
Financing Your Investment
Financing can come from:
- Standard home loan products for investment
- Releasing equity from your existing property
- Combining both for maximum flexibility
Some fees apply when restructuring or breaking fixed loans, so always calculate the cost versus benefit. At TAG, we compare investor loans across banks and specialist lenders to help you secure the right finance.
Market Research and Analysis
Before you buy an investment property, consider:
- House prices and rental yield trends
- Local property market conditions and vacancy rates
- Infrastructure, employment, and population growth
- Upcoming developments that may impact value
The Reserve Bank’s monetary policy and OCR changes also influence interest rates, which directly affect mortgage repayments and future returns.
Maximizing Your Borrowing Power
To strengthen your borrowing capacity:
- Reduce debt and consolidate existing loans
- Build savings and increase your cash deposit
- Show consistent income and strong repayment ability
- Ensure you have a clear plan and strategy for managing responsibility as a landlord
- Have an exit strategy in place
TAG helps borrowers structure loans in a way that maximises cash flow while balancing repayments and long-term growth.
Investment Property Purchase Process
Typical steps to buy an investment property:
- Calculate how much you could borrow
- Obtain pre-approval from a bank or lender
- Search on third-party websites for suitable rental property opportunities
- Make an offer and complete due diligence
- Secure finance and final approval
- Complete settlement and start renting out the property
Each step involves multiple professionals—agents, lawyers, accountants, lenders—and careful review of all fees and conditions.
Ongoing Responsibilities
Owning a rental property comes with long-term responsibility:
- Covering mortgage repayments, even during vacancy
- Ensuring compliance with Healthy Homes standards
- Managing tenants or appointing a property manager
- Handling other expenses such as rates, insurance, and maintenance
- Meeting tax obligations on rental income
A strong plan and a team of prefessionals helps ensure your property remains a sustainable investment rather than a financial burden.
