You may be earning a good income, paying your bills and thinking seriously about your future. Yet when you hear that an $800,000 investment property needs a $160,000 deposit, the goal can feel much further away than you expected.

A 20% deposit on an $800,000 investment property is $160,000, plus purchasing costs. However, you may not need to contribute that entire amount in cash. Depending on your circumstances, you may be able to use low-deposit lending, a professional lending policy, a parental guarantee or equity from a property you already own.

How much do you need for an $800,000 investment property

The right pathway depends on much more than the smallest deposit a lender will accept. Your income, debts, available equity, profession, property valuation and ability to manage the ongoing costs will all shape your options.

At Locale Wealth, we help investors work through these questions before choosing a property. We look at your goals and current position, then assess how the property, finance structure and ongoing costs could fit into your wider strategy. Where you need lending advice, we can coordinate with qualified finance professionals.

The figures below use an $800,000 house and land investment package as an example. They are indicative only and may change based on the lender, property, state and your circumstances.

The five pathways at a glance

  • A traditional 20% deposit on an $800,000 property is $160,000, plus purchasing costs.
  • Through selected lenders, an eligible investor may need approximately $75,000, including the deposit, Lenders Mortgage Insurance, transfer duty on the land and legal costs.
  • Eligible doctors and legal professionals may be able to purchase with a 5% deposit and no LMI, bringing the estimated upfront amount to approximately $60,000 to $65,000.
  • An approved parental guarantee may remove the need for a cash deposit, although purchasing costs and risks for the guarantor remain.
  • If you already own a property, you may be able to borrow against its usable equity to fund the deposit and other costs.

Every option depends on lender policies, valuation, serviceability and approval.

The smallest deposit will not always give you the most suitable outcome. Contributing less cash usually means borrowing more, which can increase your repayments and leave less room in your budget when circumstances change.

What is the traditional deposit on an $800,000 investment property?

A 20% deposit on an $800,000 investment property is $160,000. You will also need to allow for transfer duty, legal or conveyancing fees, inspections and other purchasing expenses. Keeping the base loan at 80% of the property’s value will usually help you avoid Lenders Mortgage Insurance.

The calculation is straightforward:

Property price $800,000
Deposit percentage 20%
Cash deposit $160,000
Base loan amount $640,000
Plus applicable purchasing costs

A 20% deposit can reduce the amount you need to borrow. It may also lower your repayments and save you from paying LMI.

That does not make 20% a universal requirement. Some investors choose to contribute less cash so they can buy earlier or keep more money available as a buffer. Whether that makes sense for you depends on the cost of the loan and how comfortably you can manage the additional debt.

What other purchasing costs should you allow for?

Your deposit is only one part of the amount you may need.

Other expenses can include:

  • Transfer duty
  • Conveyancing or legal fees
  • Lender application and valuation costs
  • Building and pest inspections where relevant
  • Insurance
  • Construction-related costs or variations
  • A cash buffer for delays and unexpected expenses

These costs depend on where you buy and how the purchase is structured. Before committing to a property, you need a clear view of the full project cost rather than the deposit alone.

Why can transfer duty be lower on house and land?

Where you purchase the land and construction through separate contracts, transfer duty may be calculated on the land transaction rather than the completed value of the house and land package.

For example, an $800,000 package might include land valued at much less than the completed property. If duty applies to the land component, the cost can be lower than the duty charged when purchasing an established $800,000 home.

This treatment depends on the state, the land value and the contract structure. Investor rates can also differ from concessions offered to eligible first-home buyers.

For the examples in this article, we are referring to a Western Australian house and land scenario. You should confirm the transfer duty and legal treatment of your purchase with qualified professionals before signing a contract.

Can you buy an $800,000 investment property with less than 20%?

Yes, some investors can purchase an $800,000 investment property with less than a 20% deposit. Possible pathways include low-deposit lending, professional lending policies, a parental guarantee or usable equity. Access depends on your finances, the lender, the property valuation and your ability to repay the loan.

A lender will usually consider:

  • Your income and employment
  • Your living expenses
  • Existing home loans and personal debts
  • Credit card limits
  • Your credit history
  • The number of dependants you support
  • Expected rental income
  • The property type and location
  • The lender’s valuation
  • Your ability to manage higher repayments

Having enough money for a deposit does not guarantee loan approval. In the same way, receiving approval for a certain loan amount does not mean borrowing that amount will feel comfortable once you account for your other goals and expenses.

What does a 97% LVR mean?

Loan-to-value ratio, or LVR, compares the loan with the value that the lender assigns to the property. A 97% LVR generally means the base lending represents 97% of the property’s value, leaving a 3% contribution towards the purchase price before LMI and other purchasing costs are considered.

On an $800,000 property:

  • 97% of the property value is $776,000
  • The remaining 3% is $24,000

That does not mean you only need $24,000 in total. You may also need to cover LMI, transfer duty, legal fees and other expenses.

The lender may also use its valuation rather than the price on your contract. If you agree to pay $800,000 but the lender values the property at a lower amount, you may need to contribute more money.

How could the $75,000 low-deposit option work?

In one scenario available through selected lenders, an eligible investor purchasing an $800,000 house and land package may need approximately $75,000. This amount includes the deposit, Lenders Mortgage Insurance, transfer duty on the land and legal costs.

The scenario uses an LVR of up to 97% and applies to an investment house and land package. The exact amount will depend on the value of the land, lender requirements, property valuation, loan structure and your financial position.

This option will not suit every investor. A higher LVR means you are borrowing a larger proportion of the property’s value. That can increase your repayments and leave you more exposed if the property falls in value or your income changes.

What is Lenders Mortgage Insurance?

Lenders Mortgage Insurance is a premium that protects the lender if you cannot repay the loan and the property sale does not cover the outstanding debt. It does not protect you as the borrower.

Lenders often require LMI when you borrow more than 80% of a property’s assessed value. The cost depends on the amount borrowed, the LVR and the lender’s policy.

LMI adds to the cost of buying, but that does not make it unsuitable in every case. Some investors may accept the cost to purchase with a smaller deposit. You still need to compare that benefit with the larger loan, higher repayments and pressure it may place on your budget.

Can eligible professionals purchase with a smaller deposit?

Some lenders offer specialised policies for eligible medical, health and legal professionals. These policies may allow an investor to purchase with a smaller deposit while having LMI waived or discounted. The eligible professions, income requirements, maximum LVRs and investment-loan policies differ between lenders.

Doctors and legal professionals

Eligible doctors and legal professionals may be able to purchase an investment property with a 5% deposit and no LMI through selected lenders.

A 5% deposit on an $800,000 property is $40,000. Once transfer duty on the land and legal costs are included, the estimated upfront amount in the supplied house and land example is approximately $60,000 to $65,000.

The lender will still assess the applicant’s income, profession, debts, serviceability and chosen property. Working in an eligible profession does not guarantee approval.

Other health professionals

Options may also be available to other health professionals:

Professional category Potential maximum LVR Indicative minimum deposit Possible LMI treatment
Doctors, surgeons, specialists and dentists Up to 95% 5% LMI may be waived
Allied health professionals, vets, optometrists and pharmacists Up to 90% 10% LMI may be waived or discounted through selected lenders
Registered nurses and midwives Up to 90% 10% Options may be available through selected lenders, sometimes with income limits

Lender policies change, and eligibility can differ between banks. A qualified finance professional will need to confirm which options apply to your profession and circumstances.

Can a parental guarantee remove the deposit?

Some parental guarantee arrangements may allow an investor to purchase without contributing a cash deposit towards the property price. The borrower must still qualify for the loan, and funds may still be required for transfer duty and legal costs. The guarantor also accepts a genuine financial risk.

Under this type of arrangement, a parent uses part of the equity in their property as additional security. They do not necessarily hand money to the borrower.

Can a parental guarantee remove the deposit

The guarantee does not remove the debt or transfer responsibility for the repayments. You remain responsible for the investment loan and must satisfy the lender’s serviceability requirements.

What are the risks for the guarantor?

If you cannot repay the loan, the lender may pursue the guarantor for the guaranteed amount. Their property could be at risk.

The guarantee may also affect their ability to refinance, borrow or make other financial decisions. Releasing them from the arrangement later will usually require the lender’s approval.

Both you and your guarantor should obtain independent legal and financial advice before proceeding. A smaller cash contribution is not worth creating a financial arrangement that either person does not understand or feel comfortable accepting.

Can you use equity instead of a cash deposit?

If you already own a home or investment property, you may be able to borrow against some of its usable equity to fund your next deposit and purchasing costs. The lender will assess the property value, existing debt, income, expenses and your ability to manage the increased borrowing.

Total equity and usable equity are different.

Imagine your current property has the following position:

Current equity position Amount
Estimated property value $800,000
Remaining home loan $400,000
Total equity $400,000
80% of the property value $640,000
Less the remaining loan $400,000
Indicative usable equity $240,000

The common calculation is:

$800,000 × 80% − $400,000 = $240,000 in indicative usable equity

You have $400,000 in total equity because your property is worth $400,000 more than the outstanding loan. However, lenders will not usually let you borrow against the full value of the property.

The $240,000 may be available through a loan increase or separate loan, subject to lender approval. It could help fund the investment deposit, transfer duty, legal fees and other approved costs.

Usable equity is borrowed money

Releasing $240,000 in equity does not give you $240,000 of free money. It increases the debt secured against your existing property.

You will need to manage repayments on the equity release and the investment loan. The lender will also check whether your income can support the combined debt, even if the available equity appears more than sufficient.

Using equity can reduce the amount of cash you need to save. It also links your existing property more closely to your investment strategy, so you need to understand the loan structure and risks before proceeding.

How do the five deposit pathways compare?

Potential pathway Indicative contribution for an $800,000 package Main consideration
Traditional 20% deposit $160,000 plus purchasing costs May avoid LMI and reduce the loan
Selected low-deposit lending Approximately $75,000, including stated costs Up to 97% LVR, LMI and lender criteria apply
Eligible doctor or legal professional policy Approximately $60,000 to $65,000 Profession and lender criteria apply
Parental guarantee A cash deposit may not be required Purchasing costs may remain and the guarantor accepts risk
Existing usable equity Depends on the existing property and debt Releasing equity increases overall borrowing

These figures show what may be possible, but they do not tell you which pathway suits your position.

A larger deposit can reduce your loan and repayments. A smaller deposit may let you keep more savings available or purchase sooner. A guarantee can reduce your cash contribution but places someone else’s property at risk. Using equity can help you invest without years of additional saving, but it increases the debt attached to your existing property.

Why the smallest deposit may not be the safest choice

Finding a way to meet the upfront requirement can feel like the final hurdle. In practice, you also need enough room in your budget to hold the property through changing conditions.

For a house and land investment, your planning should account for:

  • Progress payments during construction
  • Interest before rental income begins
  • Construction delays
  • Build variations
  • Council rates and insurance
  • Property management fees
  • Vacancy and maintenance
  • Changes in interest rates
  • Unexpected personal expenses

You should also consider valuation risk. If the lender values the land or completed property below the agreed price, you may need to contribute more cash.

A financial buffer gives you more room when a build takes longer than expected, the property remains vacant or your own expenses increase. Using every available dollar for the purchase may leave you with a property but no practical way to absorb the next surprise.

Common questions about investment property deposits

No. A 20% deposit is a common benchmark because it can help you avoid LMI and reduce the loan. Some eligible investors may purchase with a smaller cash deposit, professional lending policy, parental guarantee or usable equity. The lender must still approve the borrower and property.

A 10% deposit on an $800,000 property is $80,000. This amount does not include transfer duty, legal fees, LMI or other purchasing costs. The total amount required will depend on the property, lender, location and loan structure.

A 5% deposit on an $800,000 property is $40,000, excluding purchasing costs. A 5% investment lending option is not available to every borrower. It may rely on a specialised professional policy or another lender-approved structure.

Sufficient usable equity may fund the full investment deposit and some purchasing costs. The lender must approve both the equity release and the investment loan. You must also show that your income can support the additional debt and ongoing property expenses.

No. Lenders Mortgage Insurance protects the lender rather than the borrower. You remain responsible for repaying the loan and could still owe money if the property is sold for less than the outstanding debt.

Some lenders allow family guarantees for investment property purchases. Their policies and eligibility requirements differ. You must meet the lender’s borrowing requirements, and the guarantor should obtain independent advice because their property may be at risk.

Your deposit is the starting point, not the whole plan

A traditional 20% deposit on an $800,000 investment property is $160,000, plus purchasing costs. Depending on your circumstances, a selected low-deposit loan, professional lending policy, parental guarantee or usable equity may reduce the cash you need.

Each pathway changes the amount you borrow, the costs you pay and the risks you carry. A smaller upfront contribution may help you proceed sooner, but it can also increase your repayments and leave less room when construction, interest rates or personal circumstances change.

Locale Wealth can help you look beyond the deposit and assess how a potential property may fit your goals, cash flow and Financial Freedom Game Plan. We research the opportunity, complete due diligence and support you through the investment process, while qualified professionals provide lending, tax and legal advice.
