The Pros and Cons of Investment Property Deposits

Your deposit size determines more than how much you can borrow.

It sets your interest rate, your ongoing costs, and your access to certain loan features. For Morayfield investors looking to add a rental property or build a second-property portfolio, understanding how lenders assess investor deposits right now matters more than it did two years ago.

How Lenders View Investment Property Deposits Differently

Lenders treat investor deposits with more scrutiny than owner-occupier deposits. Under APRA's Prudential Standard APS 112, investor loans and interest-only loans generally attract higher risk weights than owner-occupied principal-and-interest loans at the same LVR. That means lenders hold more capital against your loan, which flows through to pricing and policy.

Most lenders require a minimum 10 per cent deposit for investment property loans, though some will lend at 5 per cent in specific circumstances. Anything below 20 per cent requires Lenders Mortgage Insurance. ADIs generally require LMI on residential loans where the LVR exceeds 80 per cent. The premium is added to your loan amount or paid upfront, and it's calculated on a sliding scale based on your LVR and the total loan amount.

Consider a Morayfield investor refinancing equity from their owner-occupied home to fund a 15 per cent deposit on a rental property in nearby Narangba. The LMI premium at 85 per cent LVR might add several thousand dollars to the loan, but it also preserves cash flow and allows the investor to enter the market sooner. Whether that trade-off makes sense depends on rental yield, vacancy rates in that suburb, and how quickly the investor expects to build equity.

The 20 Per Cent Deposit Threshold and What It Unlocks

Reaching a 20 per cent deposit avoids LMI, which is the most obvious benefit. It also gives you access to a wider range of lenders and loan products. Some lenders reserve their most competitive investor interest rates for borrowers at 80 per cent LVR or below. You're also more likely to secure interest-only repayment options, which many investors use to maximise cash flow and redirect surplus income toward paying down non-deductible debt or funding further purchases.

Morayfield sits in a growth corridor with strong rental demand driven by affordability and proximity to the Bruce Highway and Caboolture Hospital precinct. Investors in this area often balance deposit size against the opportunity cost of waiting. Saving an additional 10 per cent might take another year or two, during which time property values and rents may both increase. In our experience, clients who can demonstrate consistent rental income from an existing property and strong serviceability often move forward at 85 per cent LVR rather than delay.

Using Equity as Your Deposit

Many Morayfield investors fund their deposit by leveraging equity in their family home or an existing investment property. This avoids the need to save cash and allows you to retain liquid funds for settlement costs, minor renovations, or an emergency buffer.

Lenders calculate usable equity as the difference between your property's current value and 80 per cent of that value, minus your existing loan balance. If your Morayfield home is valued at $600,000 and you owe $350,000, your usable equity is around $130,000. That's enough to fund a deposit and cover costs on a second property without touching your savings.

Refinancing to access equity involves a new loan application and full serviceability assessment. APRA requires ADIs to assess a new borrower's capacity to service a residential mortgage at an interest rate at least 3 percentage points above the loan product rate. That buffer, combined with the debt-to-income lending limits introduced in February, means not all equity is automatically accessible. Some borrowers find they can access only part of their equity because their total debt would exceed six times their household income, which is where each ADI may fund no more than 20 per cent of new investor loans at a DTI of 6 times or greater.

We regularly see this play out with dual-income families in Morayfield who have built strong equity over the past five years but find their borrowing capacity capped by DTI rather than LVR. In those cases, structuring the loan correctly and choosing a lender with appetite for higher DTI within their internal cap becomes important.

The LMI Trade-Off for Smaller Deposits

LMI is often misunderstood. It protects the lender, not the borrower, but it gives you access to a loan you wouldn't otherwise qualify for. Under APS 112, an ADI may reduce its capital requirement through the application of eligible LMI where the insurance covers all losses up to at least 40 per cent of the higher of the original loan amount and the outstanding loan amount. The cost to you depends on your LVR and loan size, and it's a one-time expense.

For an investor purchasing a $450,000 rental property in Morayfield with a 10 per cent deposit, the LMI premium at 90 per cent LVR might be around $12,000 to $15,000. That premium can be capitalised into the loan, meaning you don't need to pay it upfront, but it does increase your loan balance and your ongoing repayments.

The decision to proceed with LMI depends on your timeline, your income, and your view of the local market. Morayfield has seen consistent rental growth over the past few years, and vacancy rates have remained low. If rental income covers most of your holding costs and you expect capital growth to outpace the LMI premium within a reasonable period, the cost may be justified. If your cash flow is tight or you're uncertain about holding the property long-term, a larger deposit and no LMI might be the more sustainable approach.

How Legislative Changes Affect Deposit Strategy

Recent changes to negative gearing and capital gains tax rules have shifted the calculation for many investors. Under the Treasury Laws Amendment (Tax Reform No. 1) Act 2026, from 1 July 2027, net rental losses from residential dwellings (other than eligible new residential dwellings) acquired on or after 7:30pm AEST on 12 May 2026 are quarantined. Losses can only be offset against other residential rental income or carried forward, not against salary or wages.

That means the tax benefit of negative gearing is deferred for new purchases of established property. For investors relying on that deduction to manage cash flow, a larger deposit and lower loan amount reduce the size of any rental loss and the reliance on immediate tax relief.

Eligible new builds include dwellings constructed on previously vacant land and dwellings replacing existing properties where the number of dwellings increases. New builds retain access to traditional negative gearing, which may influence whether an investor targets an established home in Morayfield or a newly constructed townhouse in a neighbouring development. Either way, deposit size and loan structure need to align with the tax treatment and the expected holding period.

Clients purchasing established investment properties after mid-May last year are now planning for cash-flow neutrality or positive gearing from day one, which often means a larger deposit, a shorter interest-only period, or both. For those considering investment loans, understanding how these legislative changes interact with your deposit and borrowing strategy is essential before you commit to a purchase.

Interest-Only Repayments and Deposit Size

Many investors choose interest-only repayments to maximise cash flow and redirect surplus funds toward paying down their non-deductible home loan or building a deposit for the next property. Lenders are generally more willing to approve interest-only terms when your LVR is 80 per cent or below.

At higher LVRs, interest-only approval becomes lender-specific. Some will allow it at 85 or 90 per cent LVR with a strong servicing position, while others cap interest-only at 80 per cent. The interest-only period is typically five years, after which the loan reverts to principal and interest unless you refinance or apply for an extension.

For a Morayfield investor holding a rental property long-term, the ability to keep repayments interest-only for the first five years can mean the difference between holding one property and scaling to two or three. The deposit you start with determines whether that option is available and on what terms.
