How to Finance Your First Investment Property in Australia

This guide is general information only, not financial advice. We're buyer's agents, not brokers or financial advisers. Always speak to a licensed mortgage broker and accountant before making any financing decisions.

It's Simpler Than You Think

Most people who want to buy an investment property get stuck on the finance part. They assume they need a huge deposit, a perfect credit score, and some secret knowledge about how investment loans work.

The truth is more straightforward. If you can get a home loan, you can probably get an investment loan. The process is similar, with a few key differences. This guide explains how it all works so you can have a better conversation with your broker.

How Much Deposit Do You Need?

For an investment property, most lenders want 10 to 20% of the purchase price as a deposit.

20% deposit is where things get easier. At this level, you avoid paying Lenders Mortgage Insurance (LMI), which is a one-off fee that protects the lender if you can't repay. On a $600,000 property, LMI could add $8,000 to $15,000 to your upfront costs.

10% deposit is the minimum most lenders will consider for investment loans. You'll pay LMI on top, but it gets you into the market sooner. Some investors weigh up paying LMI against the cost of waiting longer to save a bigger deposit. Your broker can run both scenarios for you.

Less than 10% is very rare for investment loans. A few lenders will go to 5%, but expect higher rates, stricter conditions, and significant LMI.

The numbers on a $600,000 property

Deposit	Amount	LMI (approx)	Total cash needed
20%	$120,000	$0	$120,000 + costs
15%	$90,000	~$6,000	$96,000 + costs
10%	$60,000	~$12,000	$72,000 + costs

"Costs" includes stamp duty, legal fees, inspections, and loan fees. Budget an extra $25,000 to $45,000 depending on the state and purchase price. Your broker or conveyancer can give you a more precise estimate.

Where Does the Deposit Come From?

There are three common ways investors fund their deposit.

1. Cash savings

The most straightforward route. You save the money in a savings account, then use it for the deposit. This is how most first-time investors fund their purchase.

If you're a few years away from having enough, a dedicated savings plan with automatic transfers makes a big difference. Even $500 a week adds up to $26,000 in a year.

2. Equity in your existing home

If you already own a home (or another property), the difference between what it's worth and what you owe is your equity. Some investors use that equity as security for an investment loan instead of a cash deposit.

How it works in general terms: If your home is worth $900,000 and you owe $500,000, your equity is $400,000. Most lenders will let you access up to 80% of your home's value minus your existing debt. In this example, that could be up to $220,000 in usable equity.

This is how many Australians go from one property to two. They didn't save a second deposit from scratch. They used the equity their first property built up over time.

Your broker can check your usable equity and explain how accessing it would affect your existing loan. This is worth exploring early because it can significantly change what's possible.

3. Guarantor support

Less common for investment properties, but some lenders allow a family member (usually a parent) to use their property as additional security. Not all lenders offer guarantor arrangements for investment loans, so ask your broker about which ones do and whether it suits your situation.

What Lenders Look At

Investment loan applications are generally assessed on four main things.

Borrowing capacity (serviceability)

This is the big one. Lenders calculate whether you can afford the repayments based on your income, existing debts, living expenses, and the rent the new property is expected to generate.

Most lenders only count around 80% of expected rental income when calculating your capacity. So if the property rents for $500 per week, they may only count $400. The rest is treated as a buffer for vacancies and costs.

They also stress-test at a rate above the actual loan rate, typically 2 to 3% higher. This is why some people with good incomes still get knocked back: the stress test is conservative by design.

What generally helps: Higher income, fewer existing debts, fewer dependents, and a property with strong rental income. Your broker can tell you specifically what would improve your position.

Credit history

Lenders check your credit file. They want to see that you pay your bills on time, you don't have defaults or judgments, and you haven't applied for multiple loans recently (each application leaves a mark).

Deposit and LVR

Your Loan-to-Value Ratio (LVR) is how much you're borrowing compared to the property's value. Borrowing $480,000 on a $600,000 property is an 80% LVR. Generally, the lower your LVR, the more lender options and better rates you'll have access to.

The property itself

Lenders don't just assess you. They assess the property too. They'll order a valuation to make sure the property is worth what you're paying. They'll also check the property type: standard houses in metro areas are generally the easiest to finance. Unusual properties (rural, very small apartments under 40sqm, student accommodation, serviced apartments) can be harder to get approved.

Investment Loan vs Home Loan: Key Differences

If you already have a home loan, here are the main differences with an investment loan.

Interest rates tend to be slightly higher. Investment loan rates are typically a bit above owner-occupied rates. Your broker can show you the current difference.

Deposit requirements can be stricter. Some lenders who offer lower deposit home loans have higher minimums for investments.

Rental income counts toward serviceability. The rental income from your new property can help you qualify for the loan. This doesn't apply to home loans because you're not renting out your home.

There may be tax implications. Investment loans can have different tax treatment to home loans. Speak to your accountant about how interest, costs, and deductions work for investment properties, especially with potential changes to negative gearing in the pipeline.

Loan Types You'll Hear About

Your broker will walk you through these options. Here's a plain-English overview so you know what they're talking about.

Principal and interest (P&I)

You pay down the loan balance plus interest each month. After 30 years, the loan is fully repaid. Monthly repayments are higher, but you're reducing your debt with every payment.

Interest only (IO)

You only pay the interest each month. The loan balance doesn't reduce. Monthly repayments are lower, but the debt stays the same.

Interest-only periods typically last 1 to 5 years before reverting to P&I. When they revert, repayments increase because you're now repaying the full balance in a shorter timeframe.

Which one is right?

It depends on your situation, your cash flow, and your goals. Each has pros and cons. This is one of the key conversations to have with your broker, because the right answer is different for everyone.

Fixed vs Variable Rate

Variable rate

Your interest rate moves up and down with the market. Variable loans usually offer more flexibility (extra repayments, redraw, offset accounts).

Fixed rate

Your rate is locked for a set period (1 to 5 years). Repayments stay the same regardless of what the market does. Breaking a fixed loan early can come with significant fees.

Split loan

Some investors fix a portion and leave the rest variable. Your broker can explain the trade-offs of each approach for your specific numbers.

Loan Structure Matters

How your loans are set up can affect your tax position, your flexibility, and your ability to buy again in the future. This is an area where getting professional advice early makes a real difference.

Some things your broker and accountant may discuss with you:

• Whether to keep your home loan and investment loan with the same lender or separate them

• How offset accounts work with different loan types

• Whether your properties should be used as security for each other (called cross-collateralisation) or kept separate

• How your loan structure affects tax deductibility
  

These are technical decisions best made with your broker and accountant working together. Getting the structure right at the start is easier than fixing it later.

How a Broker Helps

A mortgage broker compares dozens of lenders to find the best loan for your situation. They're paid by the lender (not you), and for investment loans specifically, they add value because:

• Different lenders assess rental income differently (some are more generous)

• Some lenders are more favourable for investors than others

• They can coordinate with your accountant on structure

• If you plan to buy again in the future, they can structure things to preserve your borrowing capacity
  

If you don't have a broker, we can recommend ones who specialise in investment lending and understand how property investors think.

The Steps From Here to Settlement

Here's the general timeline from "I want to buy" to "I own it."

Week 1-2: Get pre-approved. Your broker submits your financials to a lender and gets conditional approval. This tells you what you can spend. Pre-approval typically lasts 3 to 6 months.

Week 2-8: Find the property. With your budget locked in, you search for the right property. A buyer's agent can handle this for you, especially if you're buying interstate.

Week 8-10: Make an offer and go unconditional. Once you've found the property and done your due diligence (building inspection, contract review), you make an offer. If accepted, your broker converts the pre-approval to formal approval.

Week 10-16: Settlement. The legal process of transferring ownership. Your conveyancer handles the paperwork. Settlement periods are typically 30 to 90 days depending on the state and what's negotiated.

Week 16+: Tenanted and earning. Your property manager finds a tenant, and the rental income starts coming in.

Common Financing Mistakes

Not getting pre-approved first. Looking at properties without knowing what you can borrow wastes time and leads to disappointment. Always get pre-approved before you start searching.

Stretching to the absolute maximum. Just because a lender approves a certain amount doesn't mean you need to borrow all of it. Leaving headroom for rate changes, vacancies, and unexpected costs gives you breathing room.

Forgetting the costs beyond the purchase price. Stamp duty, legal fees, inspections, landlord insurance, and a cash buffer can easily add $30,000 to $50,000 on top of the purchase price. Budget for all of it.

Not comparing lenders. Rates and policies vary significantly between lenders. A broker who compares multiple options can save you thousands over the life of the loan.

Not getting the loan structure right. This is a technical area that affects your tax position and future borrowing. It's worth getting advice from both a broker and an accountant before you commit.
