Proven tips to secure deposit for investment property

The Deposit Threshold That Defines Your Investment Loan

You need at least 10% of the purchase price as a deposit to access most investment loan products, but lenders will also require proof of genuine savings and budget for additional upfront costs including stamp duty and Lenders Mortgage Insurance.

The figure that matters is your loan to value ratio. Lenders calculate this by dividing your loan amount by the property's value. At a 10% deposit, your LVR sits at 90%, which triggers LMI and limits your choice of lenders. At 20%, your LVR drops to 80%, LMI disappears, and you unlock lower investor interest rates and more flexible loan features. The difference between these two positions can add tens of thousands to your total borrowing cost.

Consider an EMT who wants to buy a rental property. They have $50,000 saved and access to another $30,000 through equity release from their current home. That $80,000 combined gives them a genuine deposit buffer, but the lender will want to see how much came from savings, how much came from equity, and whether there is enough left over to cover stamp duty, conveyancing, and building inspections. Many EMTs we work with underestimate the gap between deposit and total upfront cash required.

How Lenders Assess Your Savings as an EMT

Genuine savings must sit in your account for at least three months and show a consistent pattern of accumulation from your income.

Lenders distinguish between money you have saved over time and money that appeared suddenly, such as a gift, a tax refund, or a bonus payment. While those sources can contribute to your deposit, most lenders require at least 5% of the property value to come from genuine savings. If you have a 10% deposit and half of it came from a work bonus paid six weeks ago, the lender may ask for additional documentation or request a longer savings history.

Shift workers in emergency services often accumulate savings in irregular patterns due to overtime, penalty rates, and allowances. If your account shows variable deposits that spike and drop across months, include a payslip summary or a letter from your employer confirming your income structure. Lenders understand EMT pay cycles, but they need evidence that your savings are the result of income, not short-term borrowing.

What a 10% Deposit Really Costs You

Borrowing at 90% LVR adds Lenders Mortgage Insurance, which typically costs between 2% and 4% of your loan amount and can be capitalised into the loan or paid upfront.

LMI exists to protect the lender if you default, and the premium rises as your deposit falls. At 90% LVR on a property valued near the median for a regional area, you might pay $15,000 to $25,000 in LMI. That cost is in addition to your deposit, stamp duty, and settlement fees. Some EMTs qualify for LMI waivers depending on their employer and lender, which can save significant upfront costs and improve cashflow during the first year of ownership.

If you are borrowing close to your capacity, capitalising LMI into the loan increases your total debt and reduces the rental income buffer lenders use to assess serviceability. You will also face a higher variable interest rate compared to borrowers with a 20% deposit, which affects both your repayments and your ability to claim interest as a tax deduction under negative gearing.

How Recent Budget Changes Affect Your Deposit Strategy

From 1 July 2027, capital gains tax and negative gearing rules will change for established residential properties purchased after 12 May 2026, but new builds remain incentivised under both measures.

If you buy an established property now with a smaller deposit, you will be subject to the new rules, which replace the 50% CGT discount with inflation-based indexation and a minimum 30% tax on capital gains. Rental losses can only be offset against other residential property income, not your EMT wages. If you buy a new build, you can choose between the old 50% discount and the new indexation rules, whichever works in your favour when you sell.

This affects your deposit decision in two ways. First, new builds often require a larger deposit upfront because construction timelines delay settlement and lenders assess them differently. Second, the tax treatment over the life of the investment now varies depending on what you buy, which changes the long-term return calculation and may justify waiting to save a larger deposit for a new property rather than rushing into an established one at 90% LVR.

Using Equity Release to Boost Your Deposit

If you own your home and have built up equity, you can borrow against that value to fund part or all of your investment deposit without selling or refinancing your existing loan.

Lenders will let you access up to 80% of your home's value, minus what you still owe. If your home is worth $600,000 and you owe $300,000, you have $180,000 in available equity. You can use that to cover the deposit, stamp duty, and settlement costs for your investment property while keeping your owner-occupied loan separate. This is common among EMTs who have owned their home for several years and want to expand into property investment without draining cash savings.

The trade-off is that you are now servicing two loans, and lenders will assess your ability to meet both sets of repayments plus the investment property's costs, even if it is tenanted. Rental income is typically discounted by 20% to account for vacancy and maintenance, so your borrowing capacity does not increase dollar-for-dollar with expected rent. You can read more about this approach in our guide to equity release loans.

Interest Only Repayments and How They Change Deposit Requirements

Switching to interest only repayments reduces your monthly outgoings and can improve your borrowing capacity, but lenders assess interest only loans more conservatively and may require a larger deposit or lower LVR.

When you pay interest only, you are not reducing the principal, which means your loan balance stays the same throughout the interest only period. Lenders see this as higher risk and often cap interest only lending at 80% or 85% LVR, depending on your employment type and income stability. EMTs with permanent contracts and consistent rosters generally qualify, but casual or contract workers may face stricter limits.

If your goal is to maximise tax deductions and preserve cashflow for other investments, interest only can make sense, but only if your deposit is large enough to meet lender criteria. If you are stretching to 90% LVR, most lenders will require principal and interest repayments from day one. You can explore this structure further in our article on interest only loans.

Building Your Deposit While Property Prices Move

Waiting to save a larger deposit reduces your borrowing costs and expands your lender options, but it also exposes you to price growth in the market you are targeting.

If the property you want to buy is appreciating at 6% per year and you are saving an additional $1,000 per month, the price may be rising faster than your savings. In that scenario, entering the market sooner at a higher LVR with LMI might cost less over time than waiting and paying a higher purchase price. This calculation depends on the suburb, the type of property, and your income growth as an EMT.

Before committing, run the numbers on both scenarios. Compare the upfront LMI cost and higher repayments at 90% LVR against the projected price increase if you wait another 12 months. If you are looking at regional areas with slower growth or inner-city units with high vacancy rates, waiting may be the better move. If you are targeting high-demand areas near hospitals or emergency services hubs, acting sooner with a smaller deposit could put you ahead.
