When a deposit bond is not the right option

There are several situations in which a deposit bond is unsuitable regardless of whether you can qualify for one.

The vendor will not accept it. Vendor acceptance is not guaranteed in Queensland. If the vendor or their solicitor has specified cash only, as is increasingly common in competitive auction markets, a bond is not an option regardless of its validity. Always confirm acceptance before bidding.

Private treaty purchases with subject to finance clauses. Most private treaty residential purchases in Queensland include a finance condition. In this situation, there is usually time to arrange a cash deposit by the finance condition deadline, and the bond may be unnecessary. Bonds are most valuable in unconditional scenarios particularly auctions where there is no cooling-off period and no finance condition to rely on.

You do not yet have the settlement funds confirmed. A deposit bond is not a substitute for not having a deposit. It is a timing tool for people who will have the funds by settlement but cannot access them at exchange. If you are not certain that settlement funds will be available, a deposit bond merely defers the problem and potentially compounds it if the bond is called.

The deposit amount is very small. For smaller purchases where the 10% deposit is a modest sum, the cost and complexity of obtaining a bond may not be justified compared to simply arranging a short-term personal facility or redraw from an existing loan.

Queensland-specific note. Queensland uses standard REIQ contracts, which specify that the deposit is payable at exchange. Bond acceptance is at the vendor’s discretion and is not mandated by the contract form. In some other states, bond acceptance is more standardised but in Queensland, you are always subject to the vendor’s position. This is a meaningful practical distinction for Queensland buyers compared to buyers in New South Wales or Victoria.

The real trade-offs – what rentvesting costs that the numbers do not show

You are building equity in an asset you do not live in

Every dollar of principal you pay down on the investment property reduces a debt on a property that is not your home. When you eventually want to buy your own home, you will need a deposit for that purchase which means either selling the investment (triggering CGT), refinancing to access equity, or saving a deposit independently while continuing to hold the investment. None of these are impossible but all of them require planning.

Rental insecurity is real

Rentvesting requires you to accept the conditions of being a tenant and Australian tenancy law, while improving, still gives landlords significant rights to end leases and raise rents. An investor who owns a stable asset and rents an unstable tenancy is in a structurally uncomfortable position. This risk is manageable in practice – lease terms have been extended in most states, and good properties in tight rental markets are rarely vacated by landlords but it is a genuine consideration, particularly for families with school-age children who need locational stability.

Borrowing capacity shifts when you buy your own home

When you eventually apply for a home loan for your own property, lenders will factor in the investment loan as an existing liability. Even if the investment is positively geared or close to neutral, the existence of the loan reduces your assessed borrowing capacity for the next purchase. How much it reduces it depends on the lender’s assessment methodology and the income from the investment. A broker can model this for you before you make the rentvesting decision, it is worth knowing what your borrowing capacity looks like for your own home purchase at different stages of the investment timeline. The Borrowing Power Calculator is a useful starting point.

The psychological cost of renting while owning

This is consistently underestimated. Watching your tenant live in your investment property while you rent somewhere else runs counter to most Australian cultural intuitions about property ownership. It requires a level of strategic detachment that is easy to articulate and genuinely difficult to sustain, particularly when rent increases, lease renewals, and repair bills on the investment arrive simultaneously. Rentvestors who succeed are typically those who have genuinely internalised the financial logic of the strategy and do not measure progress by whether they own the home they live in.

Who rentvesting is right for

Rentvesting tends to suit buyers who share most of the following characteristics:

• In an established career with stable income, typically earning above $80,000, and priced out of preferred suburbs but not out of the property market entirely
• Have a deposit, typically 10% to 20% of the investment purchase price, accumulated through savings or family assistance
• Have a medium to long time horizon for the strategy, generally five years or more
• Comfortable with the responsibilities of being a landlord and have the financial buffer to manage vacancy periods and unexpected repairs
• Do not have immediate plans that would require strict locational stability, or have a secure rental arrangement that provides sufficient tenure

Rentvesting is a poor fit for buyers who expect to need the first home buyer grants in the near term, who have a deposit only sufficient for one purchase, or who are likely to want to move into their own home within two to three years. In those cases the flexibility and government assistance available for an owner-occupied purchase almost always outweighs the advantages of the investment strategy.

Rentvesting in the South East Queensland context

The Springfield and Logan corridors are among the most common rentvestor target markets in South East Queensland for buyers based in inner Brisbane. Both markets offer gross yields of 4.5% to 6%, price points accessible to buyers with $50,000 to $100,000 deposits, and infrastructure investment, the Springfield to Brisbane train line, the Coomera to Gold Coast corridor, and the broader South East Queensland Olympics infrastructure pipeline that supports medium-term capital growth expectations.

For buyers renting in New Farm, Fortitude Valley, or South Brisbane on $2,500 to $3,500 per month, owning a $550,000 Springfield townhouse with a tenant paying $550 per week produces a net holding cost that is materially less than the difference between what they pay in rent and what they would pay to own in their preferred suburb. The numbers work differently for every buyer — which is why the decision needs to be modelled for your specific income, deposit, and target markets before it is made.

When interest only makes sense for an investment loan

Interest only is the stronger choice when most or all of the following apply:

You have a principal place of residence with a mortgage. The optimal strategy is to make IO repayments on the investment (preserving the full deductible interest) and redirect every spare dollar to your home loan, which is not tax-deductible. You reduce the non-deductible debt as fast as possible while keeping the investment interest deduction maximised.

You have strong property growth expectations. If you expect the investment property to grow at six percent per year and the loan costs you 6.5% before tax (about 4.1% after tax at 37%), the net cost of holding the debt is modest compared to the capital gain. IO keeps your cashflow available to manage the investment.

You are in the 37% or 45% tax bracket. The higher your marginal rate, the more the tax system subsidises your investment interest. At 45%, the ATO covers $17,550 of the $39,000 interest bill on a $600,000 loan — nearly half. This changes the real cost calculation significantly.

You plan to sell within five to seven years. If the exit strategy is a capital gain rather than long-term income, accumulating equity through principal reduction is less important. IO keeps your cashflow optimised for the holding period.

You have significant savings in offset. Keeping savings in the offset account on an IO investment loan is structurally problematic — it is generally better to have those savings in the offset on your home loan. IO on the investment makes most sense when the cashflow saving is directed productively.

When principal and interest makes sense for an investment loan

P&I is the better choice when:

You do not have a home loan. If you own your home outright, you have no non-deductible debt to prioritise. Building equity in the investment property through P&I gives you the raw material to expand your portfolio.

You are at the lower end of the income scale. At the 32.5% bracket, the tax subsidy on investment interest is more modest. The benefit of IO is smaller, and the discipline of P&I principal reduction may outweigh the cashflow saving.

APRA policy limits apply. Since 2017, APRA has periodically imposed restrictions on interest only lending as a proportion of new loans. During periods of restriction, IO rates can be materially higher than P&I rates. If the rate premium for IO is above 0.25%, the case for P&I on investment strengthens significantly.

You want to hold the property long-term and build rental yield on original cost. As you pay down principal, your yield on the original purchase price increases — even if rent stays the same. A property bought at $700,000 with $500,000 remaining becomes positively geared much sooner on a P&I structure.

Full Worked Example: New Springfield Investment Property

The following example uses a new three-bedroom house in Springfield, purchased off the plan for $650,000 with a 10% deposit and an interest-only loan. It incorporates building depreciation and shows the full after-tax holding cost calculation for a buyer in the 37% tax bracket.

The key takeaway is that depreciation on a new property reduces the real after-tax weekly holding cost from $236 to $209 – a difference of $27 per week, or $1,404 per year, simply by obtaining a quantity surveyor’s schedule and including the building depreciation deduction. For a new property, this is one of the most accessible and highest-returning tax strategies available.

The Maths of Debt Consolidation: A Worked Example

The following example shows a homeowner carrying $43,000 in consumer debt across four accounts and the financial effect of rolling those debts into their home loan.

Before consolidation

After rolling into home loan

The monthly saving of $837 and annual saving of $10,044 looks compelling and it is real in the short term. The critical number this table does not show is the total interest paid if the $43,000 sits in the home loan for the remaining 25 years of the mortgage. At 5.8%, that $43,000 accrues approximately $38,000 in interest over 25 years. Compared to paying off a personal loan in three years at 14%, the total interest position over the full home loan term can be worse despite the lower monthly payment.

This is the central risk of mortgage-based debt consolidation. A lower monthly payment is not the same as a lower total cost. The solution is not to avoid the consolidation — it is to treat the consolidated amount as a separate debt with a shorter repayment target. A broker can structure a separate loan split for the consolidated amount with a 5 to 7 year repayment term rather than letting it sit in the main home loan for 25 years.

Split Loans: The Hybrid Option

A split loan divides your home loan into two portions with one fixed and one variable. You choose the split, commonly 50/50 or 70/30, and each portion operates under its respective product terms. The variable portion retains the offset account and flexibility features. The fixed portion provides rate certainty on that portion of the debt.

Split loans are often the most sensible choice for borrowers who are uncertain about the rate outlook or who want to hedge against being entirely wrong in either direction. They are also useful for investment loan structuring, where keeping the investment portion variable maximises offset account usage and tax efficiency, while the owner-occupied portion can be partially fixed for budget certainty.

How to decide the split ratio

The fixed portion should broadly represent the amount you want certainty on, typically the minimum monthly payment that fits comfortably in your budget. The variable portion represents the debt you want to pay down aggressively or maintain an offset against.

Example: a $700,000 loan split 60/40 with $420,000 fixed at a two year rate and $280,000 variable with offset. The fixed portion provides certainty on the majority of the debt. The variable portion allows the borrower to maintain their savings in offset and make extra repayments above the fixed cap. If rates rise, the fixed portion is protected. If rates fall, the variable portion benefits.

Split loans are arranged through the same lender across both portions. Not every lender offers split structures on competitive terms, the best deal overall may involve a lender whose split product is less flexible than a pure variable or pure fixed from another lender. A broker compares the split option against the best pure variable and best pure fixed available on the market before recommending the structure.

How to Access Your Equity

There are four main mechanisms for accessing home equity to fund an investment purchase. They each have different cost profiles, timelines and structural implications.

Loan top-up

A loan top-up which is also called a loan increase or equity release is the simplest approach. You apply to your existing lender to increase your home loan up to 80% LVR, and the additional funds are released as a lump sum or separate split that you use as the deposit for the investment purchase.

The advantage is simplicity and speed. You stay with your existing lender, the process is relatively straightforward, and in most cases the funds can be available within two to three weeks. The main limitation is that you are restricted to your current lender’s products and rates. If your current lender’s investment loan rate is not competitive, you are locked into a suboptimal position unless you also refinance.

Refinance with equity access

Refinancing allows you to move to a new lender at a more competitive rate and access your equity in the same transaction. You pay out your existing loan with the new lender’s funds, which are set at a higher amount to include the equity draw, and the difference is released to you.

The advantage is the ability to simultaneously optimise your rate and access equity. The disadvantage is the time and cost of a full refinance application which typically takes between two to four weeks, with discharge fees from your existing lender and potentially a break cost if you are on a fixed rate. If your current rate is competitive, a top-up is likely more efficient.

Line of credit

A line of credit (sometimes called a home equity loan or equity access loan) establishes a revolving credit facility secured against your home, up to your usable equity limit. You draw from it as needed rather than taking a lump sum upfront.

This structure suits investors who want flexibility, for example, those planning a staged approach to property or renovation where costs are uncertain. The main consideration is that a line of credit is typically an interest-only facility, which means the principal does not reduce over time and the risk of owing the full amount indefinitely is real. Some borrowers also find that easy access to the funds reduces their discipline around drawdown. For a straightforward investment purchase where the deposit amount is known, a top-up or refinance is usually more appropriate.

Cross-collateralisation — proceed with caution

Cross-collateralisation is where you offer your existing property as additional security for the new investment loan, rather than drawing equity separately. Instead of releasing equity from your home loan and using it as the deposit, the lender holds both properties as combined security for both loans.

Lenders sometimes encourage this structure because it is simpler for them to process and gives them greater security over your assets. However, it creates significant problems for investors over the long term:

• You lose the ability to sell either property independently. If you want to sell the investment property, the lender must revalue both properties and confirm the combined security still supports the remaining debt before they will release one from the portfolio
• Refinancing becomes much harder. Moving lenders requires both properties to be valued and transferred simultaneously, which is costly and complex
• Portfolio growth is restricted. As you try to acquire more properties, the cross-collateralised structure compounds in complexity with every additional purchase
• Loan-to-value assessments become muddled across the portfolio, making it difficult to identify and access equity in individual properties

The strong consensus among experienced property investors and finance professionals is to keep investment loans structurally separate from your home loan. Draw the equity from your home as a separate loan split, use it as the deposit, and secure the investment loan against the investment property only. This is cleaner, more tax-efficient, and gives you far greater flexibility over time.

The First Home Guarantee

The First Home Guarantee is a federal government scheme administered by Housing Australia. It allows eligible first home buyers to purchase with a 5% deposit without paying Lenders Mortgage Insurance. The government guarantees the remaining 15% of the standard 20% threshold, meaning the lender treats the loan as if an 80% LVR deposit was provided.

Use our First Home Guarantee price cap calculator to check whether your target suburb qualifies before you sign a contract.

The scheme was significantly expanded from 1 October 2025:

• No income caps: the previous thresholds of $125,000 for individuals and $200,000 for couples were removed entirely
• No cap on places: the scheme now has unlimited places rather than the previous annual allocation
• New and established homes are both eligible

Property price caps in Queensland

• Brisbane, Gold Coast, and Sunshine Coast: up to $1,000,000
• Rest of Queensland: up to $700,000

How LMI savings add up

LMI on a $700,000 purchase with a 5% deposit would typically cost between $20,000 and $28,000 depending on the lender. The First Home Guarantee eliminates this cost entirely for eligible buyers. On a $1,000,000 purchase in Brisbane, the LMI saving can exceed $40,000.

Use our LMI calculator to see your exact LMI saving at any purchase price and deposit size.

The First Home Guarantee must be applied for through an approved lender. Not all lenders are approved and your broker will know which ones are participating. You cannot apply directly through Housing Australia.

It Is Free for Most Borrowers

For the majority of home loan borrowers, using a mortgage broker costs nothing directly. Brokers are paid by the lender, not by you.

The two components of broker remuneration are:

• Upfront commission: paid by the lender at settlement, typically between 0.55% and 0.70% of the loan amount. On a $600,000 loan, this is approximately $3,300 to $4,200
• Trail commission: paid monthly by the lender for the life of the loan, typically around 0.15% to 0.20% per annum of the outstanding balance. This incentivises brokers to maintain the relationship and keep your loan competitive over time

Brokers are required to disclose their commission to you before you proceed. This transparency is mandated under the National Consumer Credit Protection Act.

It is worth noting that the commission structure creates a theoretical conflict of interest: a broker recommending a larger loan or a lender paying higher commission could earn more. This is precisely why Best Interests Duty exists, and why ASIC actively monitors broker conduct against commission patterns.
