Property Deposits Explained: The 10%, Deposit Bonds, and Where the Money Goes

The word "deposit" gets used for several different things in a property purchase, and the confusion costs buyers real money. The deposit you hand over when you sign the contract is not the same as the deposit your lender wants to see in your savings account. Understanding the difference helps you plan your purchase and avoid surprises at the worst possible moment.

This guide walks through every kind of deposit you are likely to encounter, where the money sits, what happens if a deal falls over and the alternatives to paying cash. The detail varies by state and by contract, so treat this as a map rather than a rulebook.

Two Different Deposits

The first source of confusion is that there are two distinct deposits in most purchases, and they serve different purposes.

The contract deposit is the amount you pay to the vendor when contracts are exchanged. This is commonly 10 percent of the purchase price, though it is often negotiable down to 5 percent if the vendor agrees. It signals your commitment and forms part of the price you pay at settlement.

The lender deposit is your equity in the property, the portion of the price you are not borrowing. Lenders typically want you to contribute 20 percent of the value to avoid lenders mortgage insurance, which is a one-off cost that protects the lender, not you, when you borrow with a smaller deposit. You can often borrow with less than 20 percent, but the insurance premium then applies.

These two figures can differ. You might pay a 10 percent contract deposit on exchange while your lender is funding a loan that leaves you contributing 20 percent at settlement. The contract deposit counts towards your total contribution, so it is not money on top of your equity. It is part of it, just paid earlier.

The Holding Deposit

Before contracts are exchanged, an agent may ask for a holding deposit to take a property off the market while you finalise your finance or contract review. This is usually a smaller sum, often a few thousand dollars or around 0.25 percent of the price.

A holding deposit is generally refundable and does not bind either party to the sale. It is an expression of interest rather than a commitment. The vendor can still accept another offer, and you can still walk away, though practices vary.

Get the terms of any holding deposit in writing before you pay it. Ask whether it is refundable, what it secures and how it is treated if you proceed to exchange. A holding deposit does not replace the contract deposit; it is usually credited towards it once you exchange.

Where the Deposit Is Held

A common worry is that the deposit goes straight into the vendor's pocket. In most cases it does not.

The contract deposit is held in a trust account, usually the selling agent's or the vendor's solicitor's, governed by trust account rules. The money sits there as a stakeholder fund while the sale proceeds. Neither party can simply spend it.

The deposit is generally released to the vendor at settlement, when the balance of the price is paid and the property changes hands. In some cases a vendor may seek early release of the deposit before settlement, which usually requires your consent and is something to discuss with your solicitor. Interest earned on the trust account is dealt with under the contract and state rules. [Verify]

What Happens If You Pull Out

This is where the contract deposit earns its name, because it is the amount you stand to lose if you breach the contract.

If you are still within a cooling-off period, you can typically withdraw and recover your deposit, though many states allow the vendor to keep a small penalty. Cooling-off rights differ significantly by state, and several situations remove them entirely, including auction purchases. Confirm your cooling-off position before you sign. [Verify]

If you exchange unconditionally and then fail to complete, you risk forfeiting the deposit. The vendor may also pursue further losses if the deposit does not cover them. This is the core risk of an unconditional contract, and it is why finance and other conditions matter so much.

If your contract includes conditions, such as finance approval or a building and pest inspection, and one of those conditions is not met, you can usually withdraw and recover your deposit. The protection only works if the condition is properly drafted and the deadlines are met, so read the contract carefully and act within the timeframes.

Deposit Bonds and Bank Guarantees

You do not always have to pay the contract deposit in cash. Two common alternatives let you exchange without tying up funds.

A deposit bond is a guarantee issued by an insurer or financial institution that promises to pay the deposit to the vendor if you default. No cash changes hands at exchange. At settlement you pay the full price including the deposit amount, and the bond simply lapses. Deposit bonds suit buyers whose money is tied up, such as those waiting on the sale of another property or on investments that are not easily accessed.

A bank guarantee works on a similar principle. Your bank guarantees the deposit amount to the vendor, backed by your security or savings. It is often used for larger transactions and tends to involve more paperwork than a deposit bond.

Both options carry a cost. A deposit bond fee depends on the deposit amount and the time to settlement, and a bank guarantee usually attracts a fee plus the requirement to hold security. Crucially, the vendor must agree to accept a bond or guarantee instead of cash. Not every vendor will, so raise it early and have it written into the contract.

Deposits at Auction

Auctions follow stricter rules, and the deposit is one of them.

When the hammer falls at an auction, the highest bidder is contractually bound to buy. There is no cooling-off period, and the sale is unconditional. You cannot make the purchase subject to finance or to an inspection after the auction.

You pay the deposit on the day, on the fall of the hammer, usually 10 percent of the price. You need to have arranged how you will pay it, whether by cheque, electronic transfer or a deposit bond agreed in advance. Confirm the deposit amount and accepted payment methods with the agent before you bid.

Because an auction purchase is unconditional from the moment you win, do your finance, your building and pest inspection and your contract review before you raise your hand. A buyers agent often does this groundwork on a client's behalf so the bidding decision rests on solid ground.

Genuine Savings and Why Lenders Care

When your lender assesses your deposit, they look at more than the balance. They look at how you accumulated it.

Genuine savings refers to funds you have built up and held over time, typically demonstrated over three months or more, rather than money that arrived suddenly. Many lenders want to see a portion of your deposit as genuine savings, because it signals you can manage money and meet repayments. [Verify]

Regular deposits into a savings account, term deposits and shares held in your name generally count. A lump sum that appears out of nowhere often does not, at least not without explanation. This matters because a buyer with the cash but without a savings history can still face hurdles.

If you do not have a genuine savings record, talk to a mortgage broker early. Some lenders take a different view, and some products are designed for buyers in exactly that position.

Gifted Deposits and Parental Help

Family help is common, and lenders accommodate it, provided it is documented properly.

A gifted deposit is money given to you, often by a parent, that you do not have to repay. Lenders usually require a gift letter confirming the money is a genuine gift with no obligation to repay it. Without that letter, the lender may treat the money as a loan, which affects your borrowing capacity.

A guarantor loan is a different form of family support. Here a family member, often a parent, uses the equity in their own property as additional security for your loan. This can reduce or remove the deposit you need and may help you avoid lenders mortgage insurance, but it carries real risk for the guarantor, who is exposed if you cannot repay.

Both paths have implications worth thinking through carefully, and both benefit from independent advice for the person providing the help as well as the buyer.

First Home Buyer Schemes

Government schemes can reduce the deposit a first home buyer needs, and they change regularly.

At a high level, some schemes allow eligible first home buyers to purchase with a smaller deposit while avoiding lenders mortgage insurance, by having part of the loan guaranteed. Others provide grants or concessions that effectively lower the upfront cost. Eligibility usually depends on income, the property price and whether you are a genuine first home buyer.

These schemes have caps, eligibility rules and limited places, and the details shift from year to year and between states and territories. Do not plan a purchase around a scheme without confirming the current rules and your eligibility. [Verify]

Check the relevant federal and state government sources, or ask a mortgage broker who works with the current schemes, before you commit.

Budgeting the Deposit

The deposit is the largest single number, but it is not the only cash you need at the start.

Alongside your deposit, budget for stamp duty or transfer duty, which varies by state and price and can be substantial, plus legal or conveyancing fees, building and pest inspection costs, loan establishment fees and lenders mortgage insurance if your deposit is under 20 percent. [Verify] Moving costs and initial repairs add up too.

A useful habit is to separate the contract deposit you need on exchange from the total funds you need at settlement. The contract deposit comes first, often within days of signing, while the rest is due weeks later. Knowing both numbers and their timing keeps you from being caught short.

Map these figures out before you start inspecting properties. A clear budget tells you what you can genuinely afford and stops a strong contract deposit from leaving you short on the costs that follow.
