Investment Loans for Established Properties

Purchasing an established investment property requires a different financial structure than buying your own home.

Your investment loan application will be assessed on the property's rental income potential, not just your employment income. Lenders typically apply a serviceability buffer and reduce rental income by 20-30% to account for vacancy periods and maintenance costs. Understanding how lenders calculate your borrowing capacity determines which properties remain within reach and which loan features serve your investment strategy.

Consider a legal assistant earning $65,000 annually who identifies a two-bedroom unit in Parramatta listed at $580,000 with rental income of $520 per week. With a 10% deposit of $58,000 plus stamp duty of approximately $22,000, the total upfront cost reaches $80,000. The lender assesses serviceability using $520 per week reduced by 20%, resulting in $416 per week of recognised rental income. Combined with the applicant's salary, this determines the maximum loan amount and whether Lenders Mortgage Insurance applies to the 90% loan to value ratio.

How Deposit Size Affects Your Investment Loan Options

Most lenders require a minimum 10% deposit for established investment properties. At this deposit level, you will pay Lenders Mortgage Insurance, which protects the lender if you default but adds to your upfront costs. LMI on a 90% loan can range from $15,000 to $25,000 depending on the loan amount and lender. Some legal professionals may access LMI waivers for lawyers at higher loan to value ratios, though this typically applies to partners and senior lawyers rather than legal assistants.

A 20% deposit eliminates LMI and typically provides access to better interest rate discounts. If you hold equity in your existing home, you may consider an equity release loan to fund the deposit without liquidating other investments. The interest on funds borrowed against your home to purchase an investment property becomes tax deductible when used for income-producing purposes, making this approach more tax efficient than redrawing savings.

Interest Only Repayments Versus Principal and Interest

Interest only repayments reduce your monthly loan cost, maximising cash flow and negative gearing benefits during the holding period. On a $520,000 investment loan at current variable rates, interest only repayments might sit around $2,200 per month compared to $3,100 for principal and interest. This $900 monthly difference matters when you're managing rental vacancies or unexpected maintenance.

The limitation is that interest only periods typically last five years, after which the loan converts to principal and interest unless you refinance. Your repayments then increase substantially to repay the full loan amount over the remaining term. This structure works when your income is rising or when you plan to sell the property within the interest only period. It becomes problematic if property values stagnate and you need to refinance at a higher loan to value ratio than lenders will accept.

Variable Rate or Fixed Rate for Property Investment

Variable rate investment loans provide flexibility to make unlimited additional repayments and typically include offset accounts and redraw facilities. These features let you park surplus funds against the loan to reduce interest charges while maintaining access to those funds. Most experienced property investors prefer variable rates because the flexibility outweighs the rate certainty of fixed products.

Fixed rate investment loans lock your interest cost for one to five years but restrict additional repayments and rarely include offset accounts. If you need to sell the property during the fixed period, break costs can reach tens of thousands of dollars. Fixed rates suit investors with tight cash flow who need repayment certainty, but the inflexibility becomes costly when your circumstances change.

Tax Deductions and Negative Gearing Structure

All interest paid on an investment loan is tax deductible, along with property management fees, council rates, insurance, body corporate fees, and depreciation. These claimable expenses often exceed rental income in the early years, creating a taxable loss that reduces your overall tax liability. For a legal assistant on $65,000 annual income, a $10,000 annual loss from the investment property reduces taxable income to $55,000, generating a tax refund of approximately $3,200.

Maximising tax deductions requires keeping investment costs separate from personal expenses. If you refinance your investment loan to a lower rate, the interest remains fully deductible. If you refinance and withdraw equity for personal use, only the interest on the portion funding the investment property remains deductible. This debt structure matters more as your property portfolio grows and the tax implications become more complex.

Calculating Borrowing Capacity with Rental Income

Lenders assess your ability to service an investment loan by adding recognised rental income to your employment income, then applying their serviceability buffer. Rental income is reduced by 20-30% depending on the lender, and some lenders will not recognise rental income at all until you provide a signed lease. This creates a timing issue when purchasing a vacant property where rental income cannot be verified immediately.

In a scenario where a legal assistant earns $65,000 and seeks to borrow $520,000 for an investment property generating $520 per week in rent, the lender recognises approximately $21,600 of the $27,040 annual rental income. Adding this to salary income gives $86,600 to service both the new investment loan and existing personal debts. At current lending criteria, this typically supports borrowing between $450,000 and $550,000 depending on other commitments, meaning the purchase remains viable.

Property Selection and Loan Serviceability

The property you select directly impacts loan approval because lenders assess both purchase price and rental income. Units in areas with high vacancy rates or properties requiring immediate renovation may be declined or require larger deposits. Lenders prefer established properties with consistent rental histories in suburbs showing stable or increasing values.

A two-bedroom unit in an inner-western Sydney suburb with demonstrated rental income and low body corporate fees will be assessed more favourably than a studio apartment in an oversupplied high-rise development. The same applies to regional properties where lenders may apply lower valuation ratios or decline to lend entirely. Choosing a property that meets lending criteria matters as much as finding one that suits your investment strategy.

Refinancing Investment Loans to Improve Cash Flow

Refinancing an investment loan after two to three years often provides access to lower interest rates and improved loan features. Rate discounts have increased substantially in recent years as lenders compete for investment loan business, and your initial loan may no longer reflect current pricing. Refinancing also allows you to restructure from principal and interest to interest only if your cash flow has tightened, or to release equity for a second property purchase.

Refinancing costs include discharge fees from your current lender, application fees with the new lender, and valuation costs. These typically total $1,500 to $3,000 but can be offset against the loan if you prefer not to pay upfront. A rate reduction of 0.5% on a $520,000 loan saves approximately $2,600 annually, recovering refinancing costs within twelve months.
