Understanding Investment Loan Fundamentals
An investment loan differs from an owner-occupied home loan in structure, interest rates, and the way lenders assess your application. Lenders typically charge a higher interest rate on property investor loans - usually 0.20% to 0.40% above owner-occupier rates - and they calculate your borrowing capacity differently because rental income is factored in at a discounted rate.
In our experience working with clients around San Remo and the surrounding Bass Coast, many first-time property investors underestimate how lenders view rental income. Most lenders will only count 75% to 80% of the expected rental income when calculating what you can borrow. For a property generating $450 per week in rent, the lender might only include $340 to $360 in their serviceability calculations. This affects how much you can borrow and whether your investment loan application will be approved.
The way you structure your investment property finance also has implications for your tax position. Choosing between interest-only repayments and principal and interest repayments, or between a variable rate and fixed rate, should be based on your investment strategy and cash flow requirements rather than just looking for the lowest advertised rate.
Investment Loan Deposit Requirements
You need at least a 10% deposit plus costs to purchase an investment property, though most lenders prefer 20% to avoid Lenders Mortgage Insurance (LMI). The total upfront amount includes your deposit, stamp duty, lender fees, and other purchase costs that can add 5% to 7% of the property price in Victoria.
Consider someone purchasing a $600,000 property in San Remo as their first investment. With a 10% deposit of $60,000, they would need approximately another $30,000 to $35,000 to cover stamp duty and associated costs, bringing the total required funds to around $90,000 to $95,000. Because their deposit is below 20%, they would also pay LMI, which could add another $15,000 to $20,000 to the loan amount. Their final investment loan amount would be around $555,000 to $560,000 including the LMI capitalised into the loan.
Alternatively, with a 20% deposit of $120,000 plus the same costs, they could avoid LMI entirely and borrow $510,000 instead. The higher deposit saves approximately $45,000 to $50,000 in borrowing, which translates to lower repayments and more cash flow from the rental income.
For investors who already own property, leveraging equity from an existing home can provide the deposit without needing to save additional cash. This equity release strategy is common among San Remo residents who have seen property values increase and want to expand their portfolio without selling.

Interest-Only Investment Loans Explained
Interest-only investment loans allow you to pay only the interest portion for a set period, usually one to five years. Your repayments are lower during this period because you are not reducing the principal, which can improve cash flow and maximise tax deductions on the interest paid.
The calculation is straightforward. On a $500,000 investment loan at current variable rates around 6.5%, an interest-only repayment would be approximately $2,700 per month. The same loan on principal and interest repayments over 30 years would cost around $3,160 per month. The $460 monthly difference means more rental income stays in your pocket, or you have more capacity to cover periods when the property sits vacant.
Most investors around San Remo choose interest-only structures during the accumulation phase when they are focused on portfolio growth rather than debt reduction. The interest paid is tax-deductible, and the lower repayments make it easier to hold multiple properties or to weather vacancy periods. Properties in San Remo typically experience seasonal vacancy fluctuations, with higher occupancy during summer months when tourism peaks and lower demand in winter. Having that monthly buffer can be the difference between holding the property through a quiet period or facing financial pressure.
After the interest-only period ends, the loan converts to principal and interest unless you refinance or extend the interest-only term with your lender. Your repayments will increase because you are now paying down the loan balance over the remaining loan term.
How Negative Gearing Benefits Work
Negative gearing occurs when your investment property expenses exceed the rental income, creating a taxable loss that reduces your overall income tax. This is not a benefit in itself - you are still out of pocket each week - but the tax deduction reduces how much that shortfall actually costs you.
As an example, an investor purchasing a property in San Remo for $550,000 with a 20% deposit might have an investment loan of $440,000. At an investor interest rate of 6.6%, the annual interest is approximately $29,000. Add body corporate fees of $3,500, council rates of $2,200, property management at $2,600, insurance at $1,400, and maintenance averaging $2,000, and the total annual expenses reach around $40,700. If the property rents for $480 per week, the gross rental income is $24,960. The annual loss is $15,740.
For someone earning $95,000 per year, that loss reduces their taxable income to $79,260, saving approximately $5,800 in tax at their marginal rate. Their actual out-of-pocket cost after the tax benefit is around $9,940 for the year, or $191 per week. This assumes they are holding the property for capital growth and building wealth through equity gains over time rather than relying on positive cash flow.
Understanding your claimable expenses and how to maximise tax deductions is part of a sound property investment strategy, but negative gearing only makes financial sense if the property appreciates in value. Without capital growth, you are simply subsidising a loss.
Loan to Value Ratio and Borrowing Capacity
Your loan to value ratio (LVR) is the percentage of the property value you are borrowing. A $400,000 loan on a $500,000 property is an 80% LVR. Lenders use this ratio to assess risk and determine whether you need to pay LMI and what interest rate discount they will offer.
Most lenders across Australia will lend up to 90% LVR for investment properties if you have a strong income and credit history, though the investor interest rates and LMI costs increase significantly above 80% LVR. Some lenders cap investment lending at 80% or 85% LVR depending on their current lending appetite and your financial position.
Your borrowing capacity for an investment loan is also affected by how many properties you already own. Lenders assess the total debt servicing across all your loans and factor in vacancy rates when calculating whether you can afford the new borrowing. For San Remo properties, lenders typically apply a vacancy rate assumption of 4 to 6 weeks per year when assessing rental income, reflecting the seasonal nature of the local rental market tied to tourism and holiday letting patterns.
If you own multiple investment properties or you are refinancing to access investment loan options for your next purchase, working with a broker who understands how different lenders assess investor borrowing is important. Lender policies vary significantly, and one lender might decline an application that another approves based on how they treat rental income or existing debts.
Variable Rate vs Fixed Rate for Investment Loans
Choosing between a variable interest rate and fixed interest rate depends on your tolerance for repayment changes and your view on where rates are heading. A variable rate gives you flexibility to make extra repayments, redraw funds, or refinance without penalty. A fixed rate locks in your repayments for one to five years but restricts your ability to make changes without incurring break costs.
For investment properties, most investors prefer variable rates or split their loan between variable and fixed. The variable portion allows access to any equity growth through redraw or offset, which can be used as a deposit for the next property. The fixed portion provides certainty over a portion of the repayments during the fixed term.
Investor interest rates on fixed terms are usually slightly higher than variable rates at the time of writing, though this changes depending on market conditions. The decision should be based on your cash flow needs and investment timeline rather than trying to predict rate movements. If your primary goal is to build wealth through property and you plan to hold multiple assets, maintaining flexibility often outweighs the certainty of fixed repayments.
Whether you are buying an investment property in San Remo, exploring options in nearby Inverloch, or looking further afield in growth corridors like Clyde North, the loan structure you choose should align with your broader financial goals and your capacity to service the debt through different market conditions.

Frequently Asked Questions
How much deposit do I need for an investment property loan?
You need at least a 10% deposit plus costs, though a 20% deposit is preferred to avoid Lenders Mortgage Insurance. The total upfront amount includes stamp duty and other purchase costs, which can add 5% to 7% of the property price in Victoria.
What is the difference between interest-only and principal and interest investment loans?
Interest-only loans allow you to pay only the interest portion for a set period, resulting in lower monthly repayments and improved cash flow. Principal and interest loans require you to pay down the loan balance as well, resulting in higher repayments but reducing your debt over time.
How do lenders calculate borrowing capacity for investment loans?
Lenders typically count only 75% to 80% of expected rental income when calculating borrowing capacity. They also factor in vacancy rates of 4 to 6 weeks per year and assess your ability to service all existing debts alongside the new investment loan.
Why are investment loan interest rates higher than owner-occupier rates?
Lenders view investment properties as higher risk than owner-occupied homes. Investment loan interest rates are typically 0.20% to 0.40% higher than owner-occupier rates to reflect this increased risk.
How does negative gearing work for investment properties?
Negative gearing occurs when your property expenses exceed rental income, creating a taxable loss. This loss reduces your overall taxable income, lowering your income tax, though you are still out of pocket each week before the tax benefit.
