Understanding the Basics of Investment Apartment Loans

Buying an investment apartment while separating means working with what you have right now, not what you had as a couple.

You're looking at a different lending assessment, often with a single income, possibly some equity from a settlement, and questions about whether you can even borrow enough to make it work. Investment apartment loans differ from owner-occupier lending in several ways that matter when your financial position is changing. Lenders assess rental income differently, require different deposit levels, and price the loan at a higher rate. Understanding how these differences play out in your situation helps you figure out whether this is the right move now or something to plan for once you've settled.

How Lenders Assess Rental Income on an Apartment

Lenders will use between 70 and 80 per cent of the expected rental income when calculating your borrowing capacity. The remainder accounts for vacancy periods, management costs, and maintenance. Consider someone on a $95,000 salary looking at a two-bedroom apartment in an inner suburb that rents for $550 per week. The lender uses around $385 per week of that income in the serviceability assessment, not the full $550. That difference matters when you're borrowing on a single income after separation. Body corporate fees on apartments reduce your serviceability further because they're an ongoing cost that doesn't apply to houses. An apartment with $2,000 per quarter in body corporate fees reduces your borrowing capacity by roughly $30,000 to $40,000 compared to a similar property without that cost.

Lenders also test your ability to service the loan at a rate at least 3 percentage points above the actual loan rate. If the investment loan rate is 6.5 per cent, they'll assess whether you can afford repayments at 9.5 per cent. That buffer exists to ensure you can still manage repayments if rates rise.

Deposit and Equity Requirements for Investment Property

You'll need at least a 10 per cent deposit plus costs to borrow for an investment apartment, though most lenders prefer 20 per cent to avoid Lenders Mortgage Insurance. If you're receiving equity from a property settlement, that equity can form your deposit. Someone receiving $120,000 from a settlement who wants to buy a $500,000 apartment has a 24 per cent deposit, which avoids LMI and keeps borrowing costs down. Stamp duty and other purchase costs still need to be covered. In most states, stamp duty on a $500,000 investment property sits around $18,000 to $20,000, depending on the jurisdiction. You'll also need to allow for conveyancing, building and pest inspections, and lender fees.

If your deposit sits below 20 per cent, LMI can add several thousand dollars to your upfront costs. On a $450,000 loan with a 15 per cent deposit, LMI might cost $12,000 to $15,000, depending on the lender and your circumstances. That premium can be added to the loan amount, but it increases your total debt and your ongoing repayments.

Interest Only Repayments and Cash Flow

Most investors choose interest-only repayments for the first few years because it keeps the monthly cost lower and improves cash flow. On a $400,000 loan at 6.5 per cent, interest-only repayments are around $2,165 per month. Principal and interest repayments on the same loan would be closer to $2,530 per month. That $365 difference each month can be significant when you're managing living costs on a single income and rebuilding after separation.

Interest-only loans typically run for one to five years before reverting to principal and interest. Lenders assess your ability to service the loan on a principal and interest basis even if you choose interest-only initially. After the interest-only period ends, your repayments increase. Planning for that increase matters, particularly if your income or circumstances are likely to change over the next few years.

The tax treatment also influences this decision. Interest on an investment loan is deductible against your rental income and other income, provided the apartment was acquired before certain legislative dates or qualifies as a new build. Deductions reduce your taxable income, which can offset some of the holding costs. Principal repayments are not deductible.

Borrowing Capacity When You're Separating

Your borrowing capacity depends on your income, existing debts, living expenses, and the rental income from the property. Lenders use a detailed assessment that includes everything from your car loan and credit card limits to your childcare costs and whether you're paying or receiving child support. In our experience, people underestimate how much existing debt affects their capacity. A $15,000 credit card limit costs you around $50,000 in borrowing capacity even if the card has a zero balance, because the lender assumes you could draw on it at any time.

Someone earning $90,000 per year with no dependants and minimal debt might borrow around $450,000 to $500,000 for an investment property, depending on the rental income and the lender's policy. Add $1,200 per month in child support payments and that capacity drops by $100,000 or more. If you're receiving child support or spousal maintenance, some lenders will include a portion of that income, but not all of it and not from every lender. Understanding your borrowing capacity before you start looking at properties avoids disappointment later.

Negative Gearing and Holding Costs

Negative gearing means your rental income doesn't cover all the holding costs, so you're funding the shortfall from your other income. The loss is deductible against your salary, which reduces your tax. On an apartment costing $2,400 per month to hold (loan interest, body corporate, rates, insurance) and bringing in $2,000 per month in rent, you're $400 per month out of pocket. That's $4,800 per year. At a marginal tax rate of 32.5 per cent, your tax refund covers around $1,560 of that cost, leaving you with a net outlay of $3,240 per year, or $270 per month.

For properties acquired after May 2026, new rules apply from the 2027-28 income year. Losses on established apartments purchased after that date can only be offset against income from other residential properties, not your salary. Losses are carried forward and can be used against future rental income or capital gains when you sell. New builds remain exempt and continue to allow full deductions against all income. These changes don't affect apartments you already owned or had under contract by mid-May 2026.

If cash flow is already tight, holding a negatively geared property adds pressure. Some people prefer to buy a lower-priced apartment that's closer to neutral or positively geared, even if the long-term growth potential is lower.

Variable or Fixed Rate Investment Loans

Investment loan rates sit higher than owner-occupier rates, typically by 0.3 to 0.6 percentage points. You can choose between variable, fixed, or a split loan that combines both. Variable rates allow you to make extra repayments without penalty and give you access to offset accounts, which can reduce the interest you pay. Fixed rates lock in your repayment amount for a set period, usually one to five years, which helps with budgeting but limits flexibility.

Some investors split their loan, fixing part for certainty and leaving part variable for flexibility. On a $400,000 loan, you might fix $250,000 at 6.3 per cent for three years and leave $150,000 variable at 6.6 per cent. That gives you a predictable repayment on most of the loan while still allowing extra repayments or access to an offset on the variable portion. Refinancing an investment loan after separation can also be an option if your circumstances improve or if you want to access equity for another purchase.

Building Wealth After Separation Through Property

Investment property isn't a short-term strategy. You're borrowing a large amount, holding an asset that may not generate positive cash flow for years, and relying on capital growth and tax benefits to make it worthwhile. For someone building wealth after separation, an investment apartment can be part of a broader plan that includes superannuation contributions, debt reduction, and increasing your income over time.

Apartments in inner and middle-ring suburbs tend to have lower entry prices than houses, which makes them more accessible when your deposit is limited. Growth rates vary by location, building quality, and market conditions. An apartment in a well-located block with low body corporate fees and strong rental demand will perform differently to a unit in an oversupplied precinct with high fees and rising vacancy rates. The fundamentals matter more than timing the market.

Some people prefer to wait until their income stabilises or until they've built a larger deposit before purchasing an investment property. Others use the equity from their settlement to buy sooner, accepting the cash flow pressure in exchange for getting into the market. Neither approach is wrong, but both require a clear understanding of what you can afford and what you're willing to carry.
