An investment loan for a unit gives you access to funding specifically designed for rental property. These loans differ from owner-occupier products in structure, rate, and tax treatment.
Christies Beach sits within a coastal corridor that attracts tenants working in southern Adelaide and the Fleurieu Peninsula. Proximity to the beach, Colonnades Shopping Centre, and the train line to the city makes units here consistent performers for rental income. The suburb's median unit price places entry-level apartments within reach for first-time investors, and the established unit stock around Esplanade and Beach Road offers a range of property types.
The Treasury Laws Amendment (Tax Reform No. 1) Act 2026 altered the tax treatment of investment property from 1 July 2027. Properties acquired before 7:30pm AEST on 12 May 2026 retain negative gearing under the existing rules. Properties acquired after that date and time, unless classified as eligible new builds, are subject to loss quarantine. Rental losses from those properties can only offset residential rental income or be carried forward, not offset against wages or other income. Eligible new builds retain full negative gearing until sold to a subsequent investor or until the property has been occupied for more than 12 months by the owner.
What Lenders Assess for an Investment Loan on a Unit
Lenders assess rental income, borrowing capacity, and serviceability before approving an investment loan. They calculate rental income at 80 per cent of the market rent to account for vacancy and maintenance periods. That figure is added to your other income, then lenders subtract your living expenses and existing debts. The loan is tested at the product rate plus the three percentage point serviceability buffer set by APRA.
Consider an investor purchasing a two-bedroom unit near the Esplanade in Christies Beach with an expected rental return of $400 per week. The lender will count $320 per week as assessable rental income. If the investor earns a salary of $95,000, the combined income supports borrowing, but the debt-to-income cap introduced in February this year limits total borrowing to six times gross income for no more than 20 per cent of the lender's new investor loan book. For this investor, that cap sits at $570,000. The lender's credit policy, the investor's other debts, and the unit's purchase price all determine whether the loan proceeds.
Body corporate fees for units are a recurrent cost that lenders include in serviceability. A unit with quarterly levies of $1,200 reduces net rental yield and may affect how much you can borrow. When comparing investment loan options, confirm whether the lender applies a loading to body corporate costs or simply subtracts them from rental income.
Deposit and Lenders Mortgage Insurance for Unit Purchases
Most lenders require a 20 per cent deposit for investment property to avoid Lenders Mortgage Insurance. If you borrow with a deposit below 20 per cent, LMI is charged as a one-off premium added to the loan amount or paid upfront. The premium is not refundable if you refinance or sell early.
Some lenders accept a 10 per cent deposit for units if the property is in a postcode they classify as low risk and if the borrower meets income and credit criteria. LMI at 90 per cent LVR for a $400,000 unit can add $15,000 to $20,000 to the loan amount, depending on the insurer and the lender's panel. That cost is claimable as a tax deduction, either in the year incurred or amortised over five years if the premium exceeds $100.

Interest Only or Principal and Interest Repayments
Investment loans commonly offer an interest-only period of one to five years. During that period, you pay only the interest charged each month and the principal balance does not reduce. The repayment is lower than a principal and interest loan, which can improve monthly cash flow if the property is negatively geared.
An interest-only loan on $350,000 at a variable rate of 6.5 per cent results in a monthly repayment of approximately $1,896. The same loan on principal and interest repayments over 30 years costs approximately $2,213 per month. The $317 difference may allow the investor to hold the property through periods of vacancy or unplanned maintenance without drawing on other savings. Once the interest-only period ends, the loan reverts to principal and interest unless you refinance or request an extension.
Interest-only repayments do not reduce the loan balance, so equity growth depends entirely on capital appreciation. That structure suits investors focused on portfolio growth rather than debt reduction. Principal and interest repayments build equity each month and reduce the total interest paid over the life of the loan, but require higher cash contributions from the investor if rental income does not cover the repayment.
Variable Rate or Fixed Rate for Investment Property
Variable rate investment loans allow you to make extra repayments, redraw funds, and access offset accounts without penalty. The rate moves with the lender's pricing, which means repayments can increase or decrease. Fixed rate investment loans lock the rate for a set term, usually one to five years, and repayments remain constant during that period. Most fixed rate products limit extra repayments to $10,000 or $20,000 per year and charge break costs if you refinance or repay the loan early.
Some investors split the loan between variable and fixed portions to balance certainty and flexibility. A 50 per cent split on a $380,000 loan gives you a fixed repayment on $190,000 and full flexibility on the variable $190,000. You can make extra repayments on the variable portion, access an offset account, and refinance that portion without incurring break costs on the fixed loan.
Rate discounts vary by lender and loan size. Lenders offer deeper discounts on loans above $500,000 or when you bundle multiple loans with the same institution. A 0.20 per cent discount on a $400,000 loan saves approximately $800 per year in interest. Ask your broker to compare advertised rates with the discount available to you based on your loan amount and deposit.
How Negative Gearing Rules Apply to Units in Christies Beach
Negative gearing allows you to offset a rental loss against your taxable income. If your rental income is $20,800 per year and your claimable expenses total $28,000, the $7,200 loss reduces your assessable income. For properties purchased after 7:30pm AEST on 12 May 2026 that are not eligible new builds, that loss is quarantined from 1 July 2027 and can only offset other residential rental income or be carried forward.
An investor who purchased a unit in Christies Beach in March this year retains full negative gearing. An investor purchasing the same unit after the announcement date in May will be subject to loss quarantine from 1 July 2027. The difference in after-tax cash flow depends on the investor's marginal tax rate. An investor on a 37 per cent marginal rate who loses access to negative gearing forfeits a tax saving of approximately $2,664 per year on a $7,200 loss. That cost increases holding pressure if the property remains negatively geared for an extended period.
Eligible new builds retain full negative gearing. A new unit constructed on previously vacant land or as part of a development that increases the dwelling count qualifies. A knock-down rebuild that replaces one dwelling with one dwelling does not. If you are comparing established and new units, factor in the difference in tax treatment alongside purchase price, rental yield, and capital growth prospects.
Tax Deductions and Claimable Expenses for Unit Investors
Interest on the investment loan is fully deductible if the property is rented or available for rent. Body corporate fees, council rates, landlord insurance, property management fees, and repairs are claimable in the year incurred. Depreciation on the building and fixtures is claimed over time and requires a quantity surveyor's report.
Stamp duty on the property purchase is not immediately deductible but is added to the cost base when calculating capital gains tax. LMI premiums can be claimed in full in the year paid or spread over five years if the premium exceeds $100. Loan establishment fees, valuation fees, and legal costs related to the purchase are also added to the cost base rather than claimed as annual deductions.
Keep all receipts and invoices related to the property. The ATO's rental property compliance program cross-references income reported by property managers with deductions claimed by investors. Over-claiming or claiming private expenses as investment costs triggers audits and penalties.
Refinancing an Investment Loan for Portfolio Growth
Refinancing an investment loan can release equity for a second purchase or reduce the interest rate. If your Christies Beach unit has increased in value and your loan balance has reduced, you may have access to usable equity. Lenders typically allow you to borrow up to 80 per cent of the property's current value without LMI, so any equity above your current loan balance can be released and used as a deposit on another property.
Consider an investor who purchased a unit for $350,000 three years ago with a $280,000 loan. The property is now valued at $400,000 and the loan balance is $270,000. The investor has $130,000 in equity. The lender will allow borrowing up to 80 per cent of $400,000, which is $320,000. The investor can access $50,000 in equity and use it as a deposit on a second investment property. The original loan is refinanced to $320,000, and the released equity is added to the new loan for the second property.
Refinancing costs include discharge fees from the old lender, application fees with the new lender, and valuation fees. Some lenders waive application fees if you meet loan size or portfolio thresholds. Refinancing a fixed rate loan before the term ends incurs break costs, which can exceed any rate saving. If you are considering refinancing your investment loan, confirm the total cost before proceeding.

Frequently Asked Questions
What deposit do I need for an investment loan on a unit?
Most lenders require a 20 per cent deposit to avoid Lenders Mortgage Insurance. Some lenders accept 10 per cent if the property meets their postcode and risk criteria, but LMI will be charged and added to the loan amount.
How do lenders assess rental income for an investment loan?
Lenders assess rental income at 80 per cent of the market rent to account for vacancy and maintenance. That figure is added to your other income and tested against your debts and living expenses using the product rate plus a three percentage point buffer.
Can I still claim negative gearing on a unit purchased in Christies Beach?
Units purchased before 7:30pm AEST on 12 May 2026 retain full negative gearing. Units purchased after that date are subject to loss quarantine from 1 July 2027 unless they are eligible new builds.
What is the difference between interest only and principal and interest repayments?
Interest only repayments cover only the interest charged each month and do not reduce the loan balance, which improves cash flow. Principal and interest repayments reduce the loan balance each month and build equity faster but require higher monthly payments.
Can I use equity from my Christies Beach unit to buy another investment property?
If your unit has increased in value and your loan balance has reduced, you can refinance to release equity. Lenders typically allow borrowing up to 80 per cent of the property's current value without LMI, and the released equity can be used as a deposit on another property.
