The fastest way to save a house deposit in Sydney is to shrink the target first. For an eligible first home buyer, the 5% Deposit Scheme cuts the deposit on an $800,000 home from $160,000 to $40,000 with no lenders mortgage insurance, and NSW duty relief removes stamp duty up to $800,000.

A fixed monthly saving and the First Home Super Saver Scheme then get most renters there years sooner than saving for 20 per cent.

Step 1: work out the real target

Deposit targets on an $800,000 first home in NSW
Route Deposit Main condition
20 per cent deposit $160,000 No scheme needed, no LMI
5% Deposit Scheme $40,000 Eligible first home buyer, home within the price cap, owner-occupied
Family guarantee Possibly little or none A parent offers equity in their home as security

Add a few thousand dollars for conveyancing, inspections and registration. Eligible first home buyers pay no transfer duty up to $800,000. The 5% Deposit Scheme checker confirms eligibility and the price cap, and the deposit calculator sets the target for your price.

Step 2: set a saving rate and a date

Divide the target by what you can save each month. At $1,500 a month, a $40,000 deposit takes about 27 months; with $5,000 of costs on top, about 30 months. Seeing the date makes the trade-offs concrete: a smaller first purchase, a cheaper suburb or a partner’s savings can each move it by a year. The buy now or save more calculator weighs waiting against rising prices.

Step 3: make the saving automatic

  • Separate account, paid on payday. A transfer scheduled the day your pay lands means the money is saved before it can be spent.
  • A high-interest savings account earns more while you save. Check the conditions for the bonus rate.
  • Keep it untouched. Lenders look for genuine savings: money you saved yourself and held for about three months. Regular deposits show the pattern. The genuine savings guide explains what counts.

Step 4: use the First Home Super Saver Scheme

The First Home Super Saver Scheme lets you make voluntary contributions into super and later withdraw them, with earnings, for a first home deposit. Up to $15,000 of eligible contributions a year, and $50,000 in total, can count. Concessional contributions such as salary sacrifice are taxed at 15 per cent in the fund rather than your marginal rate, so for many earners the deposit grows faster than it would in a bank account. Timing matters: request your FHSS determination before you sign a contract, and check the ATO’s current deadline for the release request after signing. The FHSS guide covers the steps.

Step 5: protect your borrowing power while you save

  • Avoid new credit. A car loan or a new credit card limit reduces what you can borrow, even if unused. Lenders count card limits as if fully drawn.
  • Close what you do not use. Buy now pay later accounts and old cards count against you.
  • Keep statements clean. Lenders read three months of statements; regular gambling transactions or unexplained transfers raise questions.
  • Pay the rent on time. Some lenders accept a rental history as part of the genuine savings evidence.

What other ways close the gap?

A family gift. Many lenders accept a gifted deposit with a signed letter. The gifted deposit guide sets out the documents. A family guarantee. A parent’s equity can replace most of the deposit; see the guarantor guide. Buying with a partner doubles the saving rate and the scheme allows two applicants; see buying with a partner. Rentvesting, buying where you can afford while renting where you live, suits some savers; see rentvesting.

How long does saving a deposit take?

Months to reach the target, before interest
Saving each month $40,000 (5% on $800,000) $80,000 (10%) $160,000 (20%)
$1,000 40 months 80 months 160 months
$1,500 27 months 54 months 107 months
$2,000 20 months 40 months 80 months
$3,000 14 months 27 months 54 months

The table shows why the target matters more than the saving rate. At $1,500 a month, the 5 per cent route takes a little over two years and the 20 per cent route almost nine, while Sydney prices keep moving. The deposit calculator runs your own figures.

Where should you keep your deposit while you save?

  • A separate savings account in your own name, so the balance builds a clean record of genuine savings. See genuine savings.
  • Not in shares or crypto close to buying. A fall in the month you need the money can cost you the property.
  • Inside super, through the First Home Super Saver Scheme, for part of it if you qualify: up to $15,000 of voluntary contributions a year count, to $50,000 in total.
  • Not lent to family or friends in the year before you apply; lenders will ask where every large transfer went.

Which mistakes slow a deposit down?

  • Saving for 20 per cent without checking whether the 5% Deposit Scheme applies.
  • Forgetting the costs on top of the deposit: inspections, conveyancing and, above the exemption, stamp duty.
  • Taking out a car loan or a new credit card while saving, which reduces borrowing power at the same time.
  • Moving money between accounts so often that the savings history is hard for a lender to read.
  • Requesting a First Home Super Saver release after signing a contract: the determination has to be requested first.

A worked plan: from nothing to a 5 per cent deposit

A couple renting in Sydney want a $800,000 home with the 5% Deposit Scheme, so the deposit target is $40,000 plus costs. They each move $900 a month into a joint savings account on payday, $1,800 a month together. At that rate they reach $40,000 in about 23 months, before interest.

Along the way they check eligibility for the 5% Deposit Scheme early, keep their credit cards to the limits they actually need, and add a costs reserve for inspections and conveyancing. At around the 18-month mark they ask for a pre-approval assessment, so any lender question about their savings history is answered before they start bidding.

Questions people ask

How much should I save for a house deposit in Sydney?

For an eligible first home buyer using the 5% Deposit Scheme, 5 per cent of the price plus a few thousand dollars for costs: about $45,000 on an $800,000 home. Without a scheme or guarantor, 20 per cent plus costs.

How long does it take to save a 5 per cent deposit?

About 27 months at $1,500 a month for the $40,000 deposit on an $800,000 home, or about 30 months including costs; it depends on the price and your saving rate.

What counts as genuine savings?

Money you saved yourself and held, usually for three months or more, shown on statements. Some lenders also accept a good rental history. A gift or inheritance is not genuine savings, though many lenders accept it with documents.

Is the First Home Super Saver Scheme worth it?

For many earners, yes: concessional contributions are taxed at 15 per cent instead of the marginal rate. You can count up to $15,000 a year and $50,000 in total, and should request the FHSS determination before signing a contract.

Should I pay off debt or save the deposit first?

Usually clear high-interest debt first: paying off credit cards lifts borrowing power more than the same money adds to the deposit. A broker can show which order gets you buying sooner.
