Saving a full deposit for a home in Perth right now is genuinely hard. With median house prices rising more than 18 percent over the past year and rental costs consuming a large share of take-home pay, many first home buyers are asking the same question: is there a faster way in?
There are two main low-deposit pathways available to Western Australian buyers in 2026. Keystart is a Western Australian government lender that requires as little as a 2 percent deposit. The First Home Guarantee Scheme is a federal program that lets eligible buyers purchase or build with a 5 percent deposit without paying Lenders Mortgage Insurance. Both are powerful. They are not the same, and choosing the wrong one for your situation can cost you time and money.
This article breaks down both schemes clearly, compares them side by side, and explains how a building broker helps you use the right pathway or both in combination.
What Is Keystart
Keystart is a Western Australian government-owned lender that was created specifically to help lower-income buyers enter the property market. It is not a grant. It is an actual home loan with its own interest rate, terms, and eligibility rules.
The headline feature is the deposit requirement. Keystart accepts deposits as low as 2 percent of the property value, and unlike most lenders, it does not require you to pay Lenders Mortgage Insurance on top of that. For a buyer building a $550,000 home, that means you could potentially enter with around $11,000 in deposit rather than the $110,000 a standard lender would want for a comparable loan without insurance.
Keystart also does not penalise buyers for using the First Home Owner Grant as part of their deposit, which creates a useful combination for eligible applicants.
However, Keystart has income and property price caps. In 2026, the income thresholds for singles, couples, and families are set at levels that target genuinely low-to-moderate income households. Keystart is also designed as a transitional lender. The expectation is that borrowers refinance to a mainstream lender once they have built enough equity. Keystart’s interest rate is typically higher than what major banks offer to well-qualified borrowers, so staying on it long-term has a cost.
You can find more detail on how this pathway works through our government grants and schemes guidance.

What Is the First Home Guarantee Scheme
The First Home Guarantee Scheme, sometimes still referred to by its earlier name the First Home Loan Deposit Scheme, is a federal government program administered through participating lenders. It allows eligible first home buyers to purchase or build a home with a 5 percent deposit while the government guarantees the remaining portion that would normally trigger Lenders Mortgage Insurance.
This is significant because Lenders Mortgage Insurance on a high-LVR loan can add tens of thousands of dollars to your total cost. The guarantee removes that expense without requiring the government to hand you any cash directly.
In 2026, there are 35,000 places available under the scheme each financial year. Places are allocated on a first-come basis through approved lenders, which means timing your application matters. The scheme applies to both established properties and new builds, including house and land packages, which makes it directly relevant to buyers working with a building broker in Perth.
Property price caps apply and vary by location. In Perth, the cap for the First Home Guarantee in 2026 sits at a level that covers most new builds in the outer metropolitan corridors, but buyers targeting established inner-ring suburbs may find the cap limiting.

Keystart vs First Home Guarantee: The Key Differences
The most important distinction is the lender structure. With Keystart you are borrowing directly from a government lender at Keystart’s rates. With the First Home Guarantee you are borrowing from a mainstream participating lender at their rates, with the government providing a guarantee in the background.
This matters because mainstream lenders generally offer more competitive interest rates and more flexible loan products than Keystart. If you qualify for the First Home Guarantee with a 5 percent deposit and your income and credit profile are strong, you will likely pay less interest over the life of the loan than you would on Keystart.
However, the deposit threshold is the critical variable. Keystart’s 2 percent minimum versus the First Home Guarantee’s 5 percent minimum sounds like a small difference but on a $550,000 build it is the difference between needing $11,000 and needing $27,500. For buyers who are saving while paying rent in Perth’s current rental market, that gap can represent more than a year of additional saving time.
Income eligibility is another dividing line. Keystart targets lower-income households with firm income caps. The First Home Guarantee has its own income thresholds but they sit higher, making it accessible to a broader range of buyers including those on moderate professional salaries.
For buyers who are comparing their house and land package options, understanding which scheme you qualify for affects which suburbs and price points are realistic.
Can You Use Both at the Same Time
Not directly. Keystart and the First Home Guarantee are separate programs administered by different entities, and you cannot combine them into a single loan. However, you can use the First Home Owner Grant alongside either scheme. The grant, currently $10,000 for eligible new builds in Western Australia, can contribute to your deposit regardless of which lending pathway you choose.
There are also situations where a buyer starts with Keystart due to a lower deposit and later refinances onto a mainstream product once their equity position improves. This is actually by design. Keystart explicitly encourages clients to refinance when they can access better rates elsewhere.
Understanding which combination makes sense for your specific income, savings, and build budget is exactly where a building broker adds value. At The Property Plug, we assess your full financial position and recommend the pathway that gets you into your home fastest at the lowest total cost, not just the lowest upfront cost.
What Perth Buyers Are Getting Wrong in 2026
The most common mistake we see is buyers assuming they do not qualify for anything and giving up before exploring their options properly. Keystart and the First Home Guarantee each have eligibility requirements, but between them they cover a wide range of income levels, deposit sizes, and property types.
The second most common mistake is applying for the wrong scheme in the wrong order, which can affect grant entitlement and delay settlement. The sequencing of applications across the First Home Owner Grant, your chosen lending pathway, and any stamp duty concessions matters and getting it wrong is easy to do without guidance.
Our team of low deposit home build specialists works through this process with buyers regularly and the difference between an organised application and a disorganised one is often several weeks and sometimes thousands of dollars.

Which One Is Right for You
If your deposit is under 3 percent of your target property value and your income falls within Keystart’s eligibility range, Keystart is likely your fastest route to ownership. Accept the higher interest rate as a temporary cost and plan to refinance within a few years once your equity grows.
If your deposit is closer to 5 percent and your income is moderate to strong, the First Home Guarantee gives you access to mainstream lender rates with no LMI, which is the better long-term financial outcome. Competition for scheme places means applying early in the financial year improves your chances.
If you are unsure which category you fall into, or if your income is variable, you have had a prior credit issue, or you are building as part of a couple where one partner’s income is irregular, a broker assessment is the right first step.
FAQs
Can I use Keystart for a house and land package?
Yes. Keystart can be used for new builds including house and land packages, provided the property value falls within their price caps. This makes it a practical option for buyers targeting Perth’s outer growth corridors where new build prices are generally lower.
Does the First Home Guarantee affect how much I can borrow?
The guarantee itself does not change your borrowing capacity. Your income, expenses, and credit profile still determine how much a lender will offer you. The guarantee simply removes the LMI cost that would otherwise apply to a high-LVR loan.
What happens if I miss out on a First Home Guarantee place?
Places are limited to 35,000 per financial year nationally. If places are exhausted you may need to wait until the new financial year in July, apply through Keystart instead, or reassess your deposit position. A broker can monitor availability and help you apply at the right time.
I earn above the Keystart income limit. What are my options?
The First Home Guarantee Scheme has higher income thresholds and is likely the more appropriate pathway. Depending on your deposit size and borrowing capacity, there may also be specialist lender options that do not require government scheme participation.
Can I get help figuring out which scheme I qualify for?
Yes. This is one of the first things we work through with new clients at The Property Plug. Book a free strategy call and we will assess your eligibility across both schemes, identify which grants apply to your situation, and outline a clear pathway forward.
