Proven Tips to Finance an Investment Unit in Alexandria

Understanding Investment Loans for Alexandria Units

An investment loan is a mortgage designed specifically for purchasing property you intend to rent out rather than live in. Lenders assess these loans differently from owner-occupier finance because you are borrowing based on rental income potential as well as your own earnings.

Alexandria has become one of inner Sydney's most active investment markets, particularly for units. The proximity to the airport, Sydney CBD, and the Green Square precinct makes it attractive to young professionals and couples who want rental accommodation close to work. High-density developments around Botany Road and near the former industrial sites mean there is a steady supply of apartments, but also competition for tenants. Units in newer buildings with good facilities tend to hold occupancy better than older walk-ups, and lenders will consider this when they assess the property as security.

When you apply for an investment loan, the lender will look at your income, existing debts, living expenses, and the rental income the property is expected to generate. They will also assess the property itself, including its condition, location, and whether it meets their lending criteria. Not all lenders will finance units in certain buildings, particularly those with high investor concentrations or cladding issues.

How Much Deposit Do You Need?

Most lenders require a minimum deposit of 10 per cent of the purchase price for an investment property, though some will lend with as little as 5 per cent if you have a strong income and credit history. Anything below 20 per cent deposit will usually trigger Lenders Mortgage Insurance, which protects the lender if you default but adds to your upfront or ongoing costs.

Consider a scenario where you are purchasing a two-bedroom unit near the Green Square end of Alexandria. You have saved a 15 per cent deposit and intend to use the property to generate passive income while continuing to rent your own home. The lender will calculate serviceability using your salary, the expected rental income (discounted by around 20 per cent to account for vacancy and costs), and a buffer of 3 percentage points above the actual interest rate. If your deposit is below 20 per cent, Lenders Mortgage Insurance will be added to the loan or paid upfront. The cost varies depending on the loan to value ratio and the lender, but it can range from a few thousand dollars to over $10,000. Some investors choose to pay this upfront to avoid increasing the loan amount, while others capitalise it into the mortgage and claim the interest as a deduction over time.

Interest Only or Principal and Interest?

You can structure an investment loan as either interest only or principal and interest. Interest only means you pay only the interest charges each month and the loan balance does not reduce. Principal and interest means you pay down the loan over time, which builds equity but results in higher monthly repayments.

Most property investors in Alexandria choose interest only for the first few years because it keeps the monthly repayment lower and maximises the amount of interest they can claim as a tax deduction. Paying down the principal does not provide a tax benefit, so from a cashflow perspective it can make sense to minimise repayments and redirect surplus funds elsewhere. However, interest only periods are typically limited to five years, after which the loan will revert to principal and interest unless you apply to extend it. Lenders have become more cautious about granting multiple interest only extensions, particularly if the property has not increased in value or if your financial position has changed.

If you are planning to hold the property long term and build wealth through both capital growth and debt reduction, a principal and interest loan may be more suitable. The repayments will be higher, but you will own more of the property over time and reduce your exposure to interest rate movements.

Variable or Fixed Rate?

Investment loans are available in both variable and fixed rate formats. A variable rate moves up or down in line with the lender's decisions, which are influenced by the Reserve Bank and market conditions. A fixed rate locks in your interest rate for a set period, typically one to five years, giving you certainty over repayments but less flexibility.

Variable rates for investment loans are generally higher than owner-occupier rates, and the rate discount you can negotiate will depend on your deposit size, loan amount, and relationship with the lender. Fixed rates for investors also sit above owner-occupier fixed rates, and you will need to decide whether the certainty is worth the premium. If you fix and rates fall, you could end up paying more than you would have on a variable loan, and breaking a fixed rate early can result in significant break costs.

Some investors use a split loan structure, where part of the loan is fixed and part is variable. This provides some certainty while retaining access to offset accounts and the flexibility to make extra repayments on the variable portion. If you are weighing up whether to refinance an existing investment loan or restructure your borrowing, a split can be a practical middle ground.

Rental Income and Serviceability

Lenders will use the expected rental income to help you service the loan, but they do not count the full amount. Most lenders apply a shading factor of 20 per cent, meaning if the property is expected to rent for $700 per week, they will only count $560 in their serviceability assessment. This accounts for vacancy periods, maintenance costs, and body corporate fees.

Alexandria units, particularly those in newer buildings close to the train station or with secure parking, tend to have lower vacancy rates than older stock further from transport. However, lenders will not distinguish between individual buildings when applying the shading factor. They will also consider your other income and expenses, and whether you can continue to service the loan if the property is vacant for an extended period.

Debt-to-income caps introduced in February 2026 mean that lenders can only approve a limited proportion of new investor loans where the total debt is six times your gross income or higher. If you are borrowing a large amount relative to your earnings, you may find that some lenders are unable to approve your application even if you can afford the repayments. This is a regulatory constraint rather than a reflection of your financial position, and it may be worth speaking with a mortgage broker in Alexandria who can direct your application to a lender with capacity under the cap.

What Changes in 2027?

From 1 July 2027, new rules will apply to the way you can claim tax deductions on investment properties. If you purchase a unit in Alexandria on or after 7:30pm on 12 May 2026, you will not be able to offset rental losses against your salary or other income. Instead, those losses will be quarantined and can only be used to reduce tax on other rental income or future capital gains on the property.

This does not mean you lose the deduction entirely, but it does change the timing. If you were relying on negative gearing to reduce your taxable income each year, you will need to factor in the cashflow impact. Properties purchased before that date, or those already under contract, are not affected and can continue to be negatively geared under the existing rules.

There is an exemption for eligible new builds, which means you can still negatively gear a brand new unit in Alexandria if it was constructed on previously vacant land or if the development increased the number of dwellings on the site. A knock-down rebuild that replaces one dwelling with one dwelling does not qualify, but a development that replaced a warehouse with a block of apartments would. If you are considering a new unit in one of the developments near the old industrial area, it may be worth confirming whether the property qualifies for the exemption before you exchange contracts.

Loan Features That Matter for Investors

When comparing investment loan products, look for features that give you flexibility and help you manage costs. An offset account can be valuable even on an interest only loan because it reduces the interest you pay without requiring you to make extra repayments that reduce the deductible debt. Some lenders do not offer offset accounts on fixed rate investment loans, so if this feature is important to you, a variable or split structure may be more suitable.

Portability is another feature worth considering. If you plan to sell the Alexandria unit and purchase another investment property in the future, a portable loan allows you to transfer the existing loan to the new property without refinancing. This can save on discharge fees, application fees, and the risk of a higher interest rate if market conditions have changed.

Some lenders also offer the ability to capitalise Lenders Mortgage Insurance into the loan rather than paying it upfront. This increases the loan amount and the interest you pay over time, but it can preserve your cash for other purposes such as stamp duty or renovation costs.

Building a Property Portfolio

If your goal is to build a portfolio of investment properties rather than own a single unit, the way you structure your first loan will affect your ability to borrow again in the future. Lenders assess each new application based on your total debt position, including existing investment loans, and your capacity to service all of your borrowing if interest rates rise or rental income falls.

One strategy is to use the equity in your first property to fund the deposit on your second purchase. Once the Alexandria unit has increased in value or you have paid down some of the principal, you can apply to access that equity without selling the property. However, this will increase your total borrowing and may push you closer to the debt-to-income cap, so timing and loan structure both matter.

If you are purchasing your first investment property with the intention of expanding your portfolio over the next few years, it is worth discussing your long-term strategy before you finalise the loan structure. The decisions you make now, such as whether to fix or vary, whether to use interest only or principal and interest, and which lender you choose, will all influence how much flexibility you have when you apply for your next loan.
