How Much Deposit Do You Really Need to Buy Your First Home?

Buying your first home is exciting — but for most people, the deposit question stops them cold before they even start looking at listings. How much do you actually need? Is 5% enough? Do you really need 20%? And what happens if you can’t hit that number?

Understanding how much deposit to buy first home is not as straightforward as a single percentage. The right number depends on the property price, where you live, and which lenders or government programs you qualify for.

This article breaks it all down clearly. By the end, you will know exactly what deposit target makes sense for your situation, what different deposit sizes actually cost you, and the most direct path to getting there.

What Does a Home Deposit Actually Mean?

A home deposit is the portion of a property’s purchase price that you pay upfront, out of your own savings. The rest is covered by your mortgage. So if a home costs $500,000 and you put down 10%, you pay $50,000 upfront and borrow the remaining $450,000 from a lender.

That much is straightforward. Where many first-time buyers get tripped up is assuming the deposit is all they need to save. It is not.

Your deposit goes toward the property price. But buying a home comes with a separate set of costs that run alongside it — and those need to come from your savings too.

How the Deposit Fits Into Your Total Buying Costs

On top of your deposit, expect to budget for costs including:

• Legal and conveyancing fees — typically $1,000 to $3,000 depending on location
• Building and pest inspection — usually $300 to $700
• Stamp duty or transfer tax — varies significantly by country and region, but can reach several thousand dollars
• Moving costs — anywhere from a few hundred to over $2,000

Using a real example: a $500,000 home with a 10% deposit means $50,000 down. But by the time you add stamp duty, legal fees, inspection, and moving costs, your total upfront cash requirement could easily reach $60,000 to $65,000.

This is why financial advisers consistently recommend saving 5% above your deposit target as a buffer for these additional expenses.

What Is the Minimum Deposit Amount Required by Lenders?

The minimum deposit amount lenders accept varies, but most require at least 5% of the property’s purchase price. Some lenders allow even lower deposits through specific government-backed schemes (more on those shortly).

The standard benchmark most lenders and financial advisers point to, however, is 20%. This figure is not arbitrary. It is the threshold at which you avoid extra charges, access better loan products, and start your mortgage from a more stable position.

The key metric lenders use here is the Loan-to-Value Ratio, or LVR. This simply measures how much of the property value you are borrowing. A 10% deposit means a 90% LVR. A 20% deposit means an 80% LVR. The lower your LVR, the less risk the lender takes on — and the better the terms they are usually willing to offer.

The 5% Deposit Option — What Comes With It

Yes, you can buy with a 5% deposit. Many lenders accept it. But there is a cost attached.

When your deposit is below 20%, most lenders require you to pay Lenders Mortgage Insurance, commonly called LMI. This is an insurance policy that protects the lender — not you — if you default on the loan. You pay the premium, but the lender benefits.

LMI is not a small fee. On a $500,000 property with a 5% deposit ($25,000 down, borrowing $475,000), LMI can cost between $12,000 and $20,000, depending on the lender and country. That amount is usually added to your loan, meaning you pay interest on it over the full loan term.

For some buyers, paying LMI to enter the market sooner still makes sense. But it is a cost worth understanding before you decide.

The 20% Deposit Benchmark — Why It Still Matters

Saving a 20% deposit does three concrete things for your finances:

1. It removes LMI entirely
2. It reduces the loan amount, lowering your monthly repayments
3. It gives you access to more competitive interest rates

The long-term difference is significant. Consider a $400,000 loan at a 6% interest rate over 30 years:

• 5% deposit ($20,000 down, borrowing $380,000 plus LMI): total interest paid over the loan term is approximately $442,000
• 20% deposit ($80,000 down, borrowing $320,000): total interest paid is approximately $372,000

That is a $70,000 difference in interest alone — before accounting for LMI. Saving longer to hit 20% is a genuine financial advantage if your situation allows it.

How Much Deposit Do You Really Need Based on Property Price?

The deposit you need scales directly with the property price you are targeting. Here is a clear reference table showing deposit requirements at four common property price points:

These figures are your deposit only — they do not include stamp duty, legal fees, or other upfront costs. As a rule, add at least 5% on top of your deposit target to cover those extras.

Use this table to set a realistic savings number based on the property prices in your target area. If homes in your city typically sell for $700,000, saving $70,000 (10%) is a very different goal from saving $140,000 (20%) — and both timelines look completely different.

Urban vs Regional Properties — Does Location Change the Target?

Absolutely. Property prices vary enormously between major cities and regional or rural areas, which means your deposit target does too.

In a high-demand city like London, Sydney, Toronto, or New York, a 20% deposit on an entry-level property could require $150,000 or more. For many first-time buyers in those markets, saving 20% is a multi-year project.

In a regional town or smaller city, a 20% deposit on a $300,000 property is $60,000 — a target that is far more achievable within 2 to 3 years for a median-income earner.

The lesson here is to set a location-specific savings target based on actual property prices in the area you plan to buy, not a national average. Researching median property prices in your specific target suburb or town will give you a far more accurate deposit goal to work toward.

First-Time Buyer Schemes That Reduce the Deposit You Need

Across most Tier-1 markets, governments offer programs specifically designed to help first-time buyers enter the property market with a smaller deposit. These programs vary by country but share a common goal: lowering the barrier to entry without forcing buyers to absorb the full cost of LMI or save for years longer.

Here is a brief overview of the main schemes by market:

• United States: FHA loans allow deposits as low as 3.5% for buyers with a credit score of 580 or above. The loan is backed by the Federal Housing Administration.
• United Kingdom: The Mortgage Guarantee Scheme allows buyers to purchase with a 5% deposit on homes up to a set value, with the government guaranteeing part of the loan.
• Canada: The First Home Buyer Incentive offers a shared equity contribution of 5% to 10% from the government, reducing the mortgage size without requiring a larger deposit.
• Australia: The First Home Loan Deposit Scheme (now the Home Guarantee Scheme) allows eligible buyers to purchase with as little as 5% without paying LMI, as the government guarantees the remaining portion.

Each program has income limits, property price caps, and eligibility criteria. Check the official program details in your country before building your plan around one.

Guarantor Loans — Using a Family Member’s Equity

A guarantor loan allows a parent or close family member to use the equity in their own property as additional security for your mortgage. In practice, this means you can borrow with a smaller deposit — sometimes as little as 5% or even less — without triggering LMI.

It is a genuinely useful option, but it carries real risk for the guarantor. If you default on the loan, your guarantor’s property can be used to cover the debt. Both parties need to understand this clearly before entering the arrangement, and independent legal advice is strongly recommended.

That said, for buyers who have supportive family and limited savings, a guarantor loan can bring homeownership years closer than it would otherwise be.

Shared Ownership and Co-Buying Arrangements

Two other options worth knowing about are shared ownership schemes and co-buying.

Shared ownership allows you to purchase a percentage of a property — typically 25% to 75% — and pay rent on the remainder. Your deposit is based only on the share you are buying, making it far more affordable upfront. These schemes are available in some form across the UK, parts of Canada, and other markets, though eligibility rules vary.

Co-buying means purchasing with a partner, sibling, or friend and splitting the deposit between you. This can halve the individual savings required, though it introduces legal and financial complexity around ownership shares and future exit plans.

Practical Down Payment Tips to Hit Your Savings Target Faster

Knowing your target is step one. Getting there efficiently is step two. These down payment tips are focused on approaches that actually move the needle on your savings — not generic advice you have read a dozen times already.

The key shift to make is treating your deposit savings like a fixed monthly expense. It is not what is left over after spending; it is the first thing that leaves your account on payday.

Beyond that, the strategies below will help you build savings faster without requiring a complete change in how you live.

Setting a Realistic Monthly Savings Rate

Start by reverse-engineering your savings target. If you need $50,000 and want to get there in 3 years, divide $50,000 by 36 months. That gives you a required savings rate of approximately $1,390 per month.

Now compare that figure to your current income and expenses. If the gap between what you earn and what you spend is already close to $1,390, you may only need minor adjustments. If it is significantly less, you need either a higher income, lower expenses, or a longer timeline.

Be honest with this calculation. Stretching your timeline from 3 years to 4 years drops the required monthly savings to around $1,040 — a difference that might make the whole plan feel achievable instead of impossible.

High-Interest Savings Accounts and Government Savings Schemes

Where you store your deposit savings matters. Keeping it in a standard transaction account means you are earning almost nothing in interest while waiting years to hit your target.

Better alternatives include:

• USA: High-yield savings accounts through online banks currently offer rates well above those of traditional banks. Some first-time buyer programs also allow IRA withdrawals for home purchases without penalty.
• UK: The Lifetime ISA allows you to save up to £4,000 per year toward your first home, with the government adding a 25% bonus on top, up to £1,000 per year.
• Australia: The First Home Super Saver Scheme allows you to make voluntary contributions to your superannuation and later withdraw them for a deposit, benefiting from lower tax rates on those savings.
• Canada: The First Home Savings Account (FHSA) lets first-time buyers contribute up to $8,000 per year, with contributions tax-deductible and withdrawals tax-free when used for a home purchase.

Using the right savings vehicle can add thousands to your deposit total over a 3 to 5-year savings window without any extra effort beyond choosing the right account.

Reducing Spending Without a Drastic Lifestyle Overhaul

Small, consistent changes add up. Here are five specific moves that free up meaningful cash each month:

• Audit your subscriptions: Most households carry 8 to 12 active subscriptions. Cancelling or sharing half of them can free up $50 to $150 per month immediately.
• Renegotiate your rent: If you have been a reliable tenant for 12 months or more, a rent freeze negotiation is worth attempting — especially in slower rental markets.
• Redirect windfalls automatically: Tax refunds, bonuses, and gifts should go directly into your deposit savings account before they touch your spending money.
• Pause lifestyle upgrades: Hold off on new furniture, car upgrades, or holidays for the savings period. Frame it as a temporary delay, not a permanent sacrifice.
• Automate the transfer on payday: Set your savings transfer to happen the morning your pay arrives. What you never see in your spending account, you never miss.

How Long Does It Actually Take to Save for a House Deposit?

The honest answer is: it depends heavily on your income, your target property price, and where you live. Saving for a house deposit is not a fixed-length project. Here are three realistic scenarios that show the range:

Scenario 1: Single buyer, median income, mid-size city.Your Annual income: $65,000. After tax and living costs, saving $800 per month. Target deposit: $60,000 (20% on a $300,000 home). Estimated timeline: approximately 6 years, or 4 years with a government scheme reducing the required amount.

Scenario 2: Couple combining incomes, mid-size city.ty Combined income: $130,000. Saving $2,000 per month combined. Target deposit: $80,000 (10% on a $800,000 home). Estimated timeline: approximately 3.5 years.

Scenario 3: Single buyer, high-cost city Annual income: $85,000. After high rental costs, saving $700 per month. Target deposit: $150,000 (20% on a $750,000 entry-level apartment). Estimated timeline: approximately 18 years at that savings rate — making a 5% deposit or government scheme almost essential.

These scenarios are not meant to discourage. They are meant to give you an honest picture so you can set a realistic plan instead of an optimistic one that falls apart six months in.

What Can Slow Down Your Savings Timeline

Even a solid savings plan can run into obstacles. The most common ones include:

• Property prices rising faster than your savings: If prices in your target area increase by 8% per year and your savings grow by 5%, the gap between your deposit and the required amount is widening, not closing.
• Unexpected expenses: Car repairs, medical costs, or job changes can wipe out months of savings. This is why a buffer above your deposit target is not optional — it is essential.
• Lifestyle creep: A pay rise that quietly turns into higher spending rather than higher savings. Review your savings rate every time your income increases.
• Underestimating total costs: Forgetting to account for stamp duty, legal fees, and inspection costs can leave you short when it matters most.

Build your plan with a 5% to 10% buffer above your deposit target. If you need $80,000, aim to save $86,000 to $88,000 before you start making offers.

Mistakes First-Time Buyers Make When Setting a Deposit Target

Most deposit-related mistakes come from working with incomplete information. Here are the four most common ones — and the correction for each.

Mistake 1: Targeting the minimum deposit without accounting for LMI. Saving 5% and thinking you are ready, only to discover LMI adds $15,000 or more to your costs. The correction: always calculate LMI into your total upfront cost before deciding on a deposit target.

Mistake 2: Forgetting additional upfront costs. Stamp duty alone can run to several thousand dollars, depending on your location and property price. The correction: add a minimum of 5% on top of your deposit to cover all additional buying costs.

Mistake 3: Not factoring in the lender’s stress test. Most lenders assess your borrowing capacity at a rate 2% to 3% above the current loan rate. If your repayments are only affordable at the current rate, you may not pass the stress test. The correction: Use an online mortgage calculator at a rate 2.5% above current rates to check your real borrowing capacity.

Mistake 4: Waiting too long in a rising market. Holding out for a 20% deposit while prices rise significantly can leave you permanently priced out. The correction: model both scenarios — entering now with 10% plus LMI versus waiting another 2 years for 20% — and compare the actual numbers before deciding.

Why Saving More Than the Minimum Often Makes Financial Sense

The numbers make a clear case. Consider two buyers targeting a $500,000 home:

• Buyer A saves 10% ($50,000) and buys now. LMI costs approximately $9,000. Total loan: $459,000. At 6% over 30 years, total interest paid: approximately $534,000.
• Buyer B saves 20% ($100,000) and buys 18 months later. No LMI. Total loan: $400,000. Total interest paid: approximately $464,000.

Buyer B saves approximately $79,000 over the life of the loan. The 18-month wait cost Buyer B $50,000 more in savings effort but returned $79,000 in long-term cost reduction.

This is not a universal argument for always waiting. If property prices in your area are rising sharply, the maths can flip. But if prices are stable or moderate, pushing toward 20% often pays for itself many times over.

Conclusion

There is no single answer to how much deposit to buy a first home — and that is actually good news. It means there is a path into the market for buyers at different income levels and savings stages.

The core takeaways from this guide:

• The minimum deposit is typically 5%, but going below 20% usually means paying LMI
• Your deposit is only part of your upfront savings requirement — budget for additional costs on top
• Government schemes can reduce the deposit threshold significantly if you qualify
• The right deposit target depends on your property price, location, and timeline

Your next step is a concrete one: take your target property price, decide on a deposit percentage, add 5% for additional costs, and calculate the monthly savings rate you need to get there in your chosen timeframe. If that number feels out of reach, revisit the government schemes in your country or speak with a mortgage broker who can map out your actual options.

The deposit question does not have to be the thing that stops you before you start.
