Buying an investment apartment brings specific lending considerations that differ from both owner-occupied purchases and standalone investment houses.
Apartment lending typically involves higher deposit requirements, interest rate adjustments tied to property type, and lender scrutiny of body corporate health and rental yield. The differences matter most at application stage, where lenders assess not only your income and expenses but also the income-generating capacity of the property itself.
Deposit and LVR expectations for investment apartments
Most lenders cap investment apartment loans at 90 per cent LVR, though some restrict higher-density stock to 80 per cent without mortgage insurance.
Consider a buyer looking at a two-bedroom unit in Narellan's newer developments near the town centre. If the purchase requires an 85 per cent LVR, the lender will assess whether the complex meets minimum apartment lending criteria, including total unit count, owner-occupier ratio, and whether any single entity owns more than a set percentage of lots. Lenders may decline or reduce the LVR if the complex is still under construction, has fewer than six completed sales, or carries defect disputes on title. For apartment purchases in Narellan, where a number of medium-density developments have been completed in the past few years around the town centre and Narellan Vale, these criteria are particularly relevant, as some complexes remain relatively new and may not yet meet every lender's seasoning requirements.
Where the lender approves an LVR above 80 per cent, Lenders Mortgage Insurance applies. The premium is calculated on the loan amount above 80 per cent LVR and is paid upfront, though it can be capitalised into the loan. That premium is not a claimable expense against rental income in the year it is paid.
How interest rates differ for investment apartment loans
Investment apartment loans generally attract a rate loading compared to owner-occupied house loans, and some lenders apply an additional margin for apartments specifically.
The rate structure reflects the lender's risk weighting under prudential standards. An investment loan on an apartment may carry a rate 0.20 to 0.40 percentage points higher than an equivalent owner-occupied loan on a house, depending on the lender and the LVR. That margin compounds over time. At current variable rates, the difference between an owner-occupied house loan at 6.00 per cent and an investment apartment loan at 6.40 per cent would amount to several thousand dollars per year on a loan of a typical size. Both variable rate and fixed rate products are available, and the choice depends on your cash flow needs and interest rate outlook. Fixed rates lock in certainty but remove the flexibility to make extra repayments above a set threshold without incurring break costs.
Interest-only terms are common for investment loans, as they reduce monthly outgoings and allow the investor to claim the full interest amount as a deduction. Most lenders offer interest-only periods of up to five years initially, with the option to revert to principal and interest or extend the interest-only term subject to a fresh serviceability assessment.

Body corporate fees and lender serviceability calculations
Body corporate levies are treated as a cost against rental income when lenders assess serviceability.
For an apartment in a complex with a pool, gym, or lift access, quarterly levies might range from $800 to $1,500 or more. Lenders deduct these amounts, along with council rates, insurance, and a vacancy allowance, from the gross rental income before calculating how much the property contributes to your borrowing capacity. In some cases, a high body corporate levy relative to rent can limit how much you can borrow, even if your personal income is strong. Lenders also review the body corporate's sinking fund balance and any upcoming special levies flagged in the strata report. A sinking fund below the recommended level, or a history of frequent special levies, may lead to a reduced valuation or declined application.
If you are purchasing in a complex that is still settling or where the original developer retains ownership of unsold units, some lenders will not proceed until a minimum percentage of units have settled to private owners. This is particularly relevant in Narellan, where several apartment developments have been completed in recent years and may still be transitioning from developer control to owner-occupied or investor-owned status.
Rental income shading and vacancy assumptions
Lenders apply a shading percentage to the rental income you declare, typically between 70 and 80 per cent, to account for vacancy periods and maintenance costs.
If an apartment is advertised at $550 per week, the lender might assess it at $440 per week after applying an 80 per cent shading factor. That equates to roughly $22,900 per year in assessed rental income, from which body corporate, rates, and insurance are then deducted. The net figure is added to your other income when calculating serviceability. For apartments in areas such as Narellan, where rental demand is supported by proximity to the town centre, Narellan Library, and the nearby train station at Campbelltown, vacancy rates are generally moderate, but lenders still apply conservative assumptions regardless of local conditions. Rental income from a property you do not yet own can only be included if you have a signed lease or a rental appraisal from a licensed property manager dated within the past 90 days.
Tax treatment and negative gearing under current legislation
Interest on an investment apartment loan is deductible against rental income, along with other holding costs such as property management fees, insurance, and depreciation.
For apartments purchased before 12 May 2026, or for eligible new builds purchased after that date, any loss can be offset against your other income, including salary. This is commonly referred to as negative gearing. For established apartments purchased after 12 May 2026, losses from the 2027-28 income year onward can only be offset against other residential property income, not against wages or business income. Losses that cannot be used in a given year are carried forward. If you purchased an apartment under contract before 12 May 2026, even if it settled afterward, the property is grandfathered under the prior rules. Buyers considering an off-the-plan apartment should confirm with their solicitor and accountant whether the contract date or settlement date determines the tax treatment, as this varies depending on the structure of the purchase and the stage of construction.
Loan structure and offset account limitations
Most investment apartment loans are structured with an offset account, though not all lenders offer offset functionality on interest-only investment products.
Where an offset is available, it reduces the interest charged on the loan but does not reduce the interest amount you can claim as a deduction. The deduction is based on the loan balance, not the net balance after offset. For investors who want to preserve cash flow and maximise deductions, leaving funds in an offset account rather than paying down the loan provides flexibility without reducing the deductible interest. However, offset balances do not reduce the loan amount for the purpose of calculating the loan-to-value ratio under lending standards, so they do not help you avoid or reduce Lenders Mortgage Insurance at origination. Some investors split their loan between a fixed portion and a variable portion with offset, allowing them to lock in part of the rate while retaining flexibility on the remainder. Refinancing to access a better rate or additional features is common once the property has seasoned and equity has built.
When a guarantor or equity release is required
If your deposit or borrowing capacity falls short, some lenders will accept a guarantee from a parent or family member, or allow you to use equity from another property.
A guarantor provides security over their own home to support your loan, typically up to the amount of the shortfall rather than the full loan balance. The guarantor's property is assessed for available equity, and their income and liabilities are included in the serviceability calculation. Most guarantees can be released once the loan balance falls below 80 per cent of the investment property's value, subject to a revaluation and the guarantor's request. Equity release from an existing property, whether your home or another investment, works by refinancing that property to access funds for the deposit and purchase costs. The additional borrowing is assessed against the existing property's value and your overall serviceability. Both approaches are common for buyers in Narellan who are stepping into investment property ownership for the first time and do not yet have sufficient cash savings for a 10 or 20 per cent deposit.
Preparing your application for an investment apartment loan
Lenders assess your income, liabilities, living expenses, and the rental income and costs associated with the property.
Your application will need to include payslips, tax returns if you are self-employed or receive rental income from other properties, and details of all existing debts including credit cards, personal loans, and other mortgages. The lender will also require a valuation of the apartment, a copy of the contract of sale, and a strata report covering the body corporate's financial position, insurance arrangements, and any building defects or legal disputes. For apartments in Narellan, where several developments are relatively new, the strata report is particularly important, as it will show whether the complex has adequate sinking fund reserves and whether any defect claims are underway. Lenders may decline or reduce the loan amount if the strata report reveals material issues, even if the apartment itself is in good condition.
If you have other investment loans or are building a portfolio, the lender will assess your total exposure and may apply portfolio lending limits or require additional equity. Some lenders cap the number of investment properties they will finance for a single borrower, or limit total investment lending to a multiple of your income.

Frequently Asked Questions
What deposit do I need for an investment apartment loan?
Most lenders require a minimum 10 per cent deposit, though some cap investment apartment loans at 80 per cent LVR depending on the property. Lenders Mortgage Insurance applies if the LVR exceeds 80 per cent, and the premium is calculated on the amount borrowed above that threshold.
How do lenders treat body corporate fees when assessing an investment apartment loan?
Body corporate levies are deducted from the gross rental income when calculating serviceability. Lenders also review the body corporate's sinking fund balance and any upcoming special levies flagged in the strata report, as these can affect the property's valuation and borrowing capacity.
Can I claim interest on an investment apartment loan as a tax deduction?
Yes, interest on borrowings used to purchase or hold a rental property is deductible against rental income. For properties purchased before 12 May 2026 or eligible new builds, losses can be offset against other income including salary, subject to the current negative gearing rules.
What is rental income shading and how does it affect my borrowing capacity?
Lenders apply a shading factor, typically 70 to 80 per cent, to the rental income you declare to account for vacancies and maintenance costs. The shaded amount is used in serviceability calculations, which means the lender assesses less rental income than the property actually generates.
Do investment apartment loans have higher interest rates than owner-occupied loans?
Yes, investment loans generally attract a rate loading compared to owner-occupied loans, and apartments may carry an additional margin depending on the lender. The difference is typically between 0.20 and 0.40 percentage points, reflecting the lender's risk weighting under prudential standards.
