Investment property finance has become increasingly attractive. Real estate has historically appreciated over 5.5% annually since 1963, outpacing inflation’s 3.9% annualised rate. This remarkable growth potential continues to draw individuals seeking to build wealth through property investment.
However, financing investment property differs significantly from purchasing a primary residence. Conventional loans for investment properties typically require down payments of 15% to 25%, compared to as little as 3% for primary homes. Additionally, lenders generally expect higher credit scores—often a minimum of 620 with 25% down or 680 with 15% down. Furthermore, interest rates for investment property financing are usually 0.5% to 0.75% higher due to increased risk.
Despite these challenges, investment properties offer substantial benefits. Investors can lower their taxable income by claiming tax deductions for property taxes, maintenance expenses, depreciation, and mortgage interest. Location remains paramount in property investment success, with properties near public transport, healthcare, retail, and childcare typically commanding higher rents. For those seeking additional funding options, approximately 75% of anticipated rental income can be counted toward qualifying income for investment property loans.
Understanding the Basics of Property Investment

Property investment involves purchasing real estate specifically to earn returns through rental income, future resale value appreciation, or both. Unlike buying a home, investment properties serve as wealth-building vehicles that generate ongoing financial benefits.
Most property owners are classified as investors rather than businesses, especially when they maintain regular employment and have minimal involvement in day-to-day rental activities. This distinction affects tax treatment and reporting requirements for your investment.
Property investment typically offers several core advantages. First, it provides steady cash flow through rental income that often strengthens over time as mortgages are paid down. Second, real estate values have historically shown strong appreciation potential, allowing investors to build equity while waiting for optimal selling conditions. Third, property investors benefit from numerous tax advantages, including deductions for reasonable costs of owning, operating, and managing properties.
Nevertheless, property investment involves specific risks worth considering:
- Rental income may not always cover mortgage payments and property expenses
- Properties can experience vacancy periods requiring out-of-pocket expense coverage
- Rising interest rates can reduce disposable income by increasing repayments
- Properties offer less liquidity than other investments—you cannot easily sell a portion when cash is needed
When selecting investment properties, location remains paramount. Areas with high growth potential, strong rental yields, and low vacancy rates typically perform best. Notably, property near amenities such as public transport, schools, and shopping centres often attracts more reliable tenants.
Common investment strategies include the “buy and hold” approach for long-term capital growth, positive cash flow investing, where rental income exceeds expenses, and negative gearing, where initial losses are offset against other income for tax purposes.
While property investment doesn’t require specialised knowledge, successful investors conduct thorough research, understand local market conditions, and carefully assess each property’s potential return on investment before committing.
How to Prepare Financially Before You Apply?

Before applying for financing for an investment property, you must do extensive financial planning. First, understand that most lenders require at least 20% of the property’s value as a deposit to avoid Lender’s Mortgage Insurance (LMI). For example, a property valued at £993,843 would need a deposit of approximately £198,768.
Beyond the deposit, you must account for additional upfront costs that often total around 5% of the purchase price. These include:
- Stamp duty (varies by state/territory)
- Legal fees and conveyancing
- Building and pest inspections
- Mortgage establishment fees
- Property transfer fees
- Insurances (building, contents, landlord)
Accordingly, you must calculate ongoing expenses to ensure your investment remains viable. Nearly 65% of property investors report negative cashflow in their portfolios, primarily because they underestimate recurring costs like property management fees (5-8% of weekly rent), council rates, strata fees, maintenance, and potential vacancy periods.
Creating a financial buffer is essential—experts recommend keeping 5-10% of annual rental income as an emergency fund for unexpected repairs and allocating 2-4 weeks’ rent to cover potential vacancies.
Furthermore, your credit score significantly impacts both approval chances and loan terms. Lenders typically prefer scores of 680 or higher for investment property loans, though some may consider scores as low as 620 with less favourable terms. To improve your score, pay bills on time, reduce existing debt, and limit new credit applications.
Eliminating “bad debt” like credit cards and personal loans before applying is equally essential, as these can limit your borrowing potential. Instead, focus on building “good debt”—money borrowed to acquire income-producing assets.
Finally, use online borrowing power calculators from major banks to estimate your lending capacity based on income, expenses, and existing financial commitments. These tools help identify how much you can realistically borrow while maintaining financial stability.
Choosing the Right Investment Property Loan
Selecting an appropriate loan is a critical step in your investment property journey. Interest rates for investment mortgages typically range between 0.25% to 0.75% higher than owner-occupied loans, reflecting the increased risk lenders associate with investment properties.
When exploring financing options, you’ll encounter several loan structures:

- Fixed-rate loans lock in your interest rate for 1-5 years, providing payment stability if rates rise—three-year fixed rates for investment properties currently average around 5.59% p.a.
- Variable-rate loans fluctuate with market changes, offering flexibility and typically including features like offset accounts.
- Split loans offer a balance between security and flexibility by combining both fixed and variable components.
An important consideration is choosing between principal and interest repayments and interest-only options. Interest-only loans allow borrowers to pay the interest portion for a set period (typically 5-10 years), lowering initial repayments. This approach is particularly popular among investors, as interest payments on investment properties are tax deductible.
Moreover, lenders typically assess only 70-80% of your expected rental income when calculating borrowing capacity, accounting for potential vacancies and maintenance costs. Due to income variability, banks apply even more conservative assessments for short-term rentals like Airbnb.
Offset accounts deserve special attention, as they allow you to use savings to reduce interest charges while maintaining access to your funds. Unlike redraw facilities, withdrawals from offset accounts don’t affect the tax deductibility of loan interest. This distinction becomes particularly important if you plan to convert your property from personal to investment use.
Your investment loan choice should align with your overall investment strategy, tax position, and risk tolerance rather than being driven solely by interest rates.

Conclusion – Investment Property Finance
Investment property finance offers a promising path to wealth building, albeit with distinct challenges compared to residential home purchases. Thorough financial preparation is the cornerstone of successful property investment. Most importantly, prospective investors should accumulate a substantial deposit—typically 20% of the property value—while budgeting for additional costs that generally amount to 5% of the purchase price.
Loan selection deserves careful consideration based on individual circumstances rather than interest rates alone. Fixed-rate loans provide certainty during market fluctuations, whereas variable options offer flexibility through features like offset accounts. Split loans combine these benefits, giving investors both stability and adaptability. The interest-only approach remains particularly popular among property investors due to its tax advantages and lower initial repayments.
Location continues to reign supreme when selecting investment properties. Areas near essential amenities typically attract reliable tenants and command higher rents, consequently improving return on investment. Though property investment carries inherent risks, such as vacancy periods and unforeseen maintenance costs, creating a financial buffer mitigates these potential issues.
Despite higher barriers to entry than owner-occupied purchases, investment properties deliver significant tax benefits through deductions on mortgage interest, depreciation, maintenance, and property taxes. These advantages, combined with historical appreciation rates exceeding inflation, make property investment an attractive long-term strategy for wealth creation. Successful investors balance enthusiasm with pragmatism, conducting thorough research while maintaining realistic expectations about returns and responsibilities.
What are the key financial considerations for first-time property investors?
First-time investors should prepare a substantial deposit, typically 20% of the property value, and budget for additional costs of about 5% of the purchase price. Understanding ongoing expenses and creating a financial buffer for unexpected repairs and potential vacancy periods is also crucial.
