There is a straight trade at the centre of this decision, and most pages about Keystart only show you one half of it.
Keystart lets you buy or build with a much smaller deposit than a bank will accept, and without lender’s mortgage insurance. In return you pay a higher interest rate, you accept limits on what you can buy and how much you can earn, and you take on a loan you are expected to leave.
That is the whole comparison. Everything below is detail.
We should say plainly where we sit. House & Land Co is an independent building advisory in Perth. We are not a lender, not a mortgage broker, and not Keystart. We do not earn anything from which loan you choose. Our service is free to you — see how we are paid. If you are starting from scratch, the overview is at Keystart home loans in WA.
Side by side
| Keystart | A standard bank loan | |
|---|---|---|
| Deposit | 2% — Keystart’s wording is “the higher of 2% or $2,000”, and it “may vary dependent on location and purchase price” (Low Deposit Home Loan) | Typically 20% to avoid LMI, or 5% with LMI |
| Lender’s mortgage insurance | Not charged on anything — every product in the range is published with no lender’s mortgage insurance (Compare our home loans) | Charged below 20% deposit, often thousands |
| Interest rate | Variable only, no fixed option, generally above the bank market — current rates by product | Fixed or variable, competitive |
| Income limit | Yes — a hard ceiling, set per product and per region — current limits | No ceiling |
| Property price cap | Yes — a hard ceiling, set per product — current cap | No cap beyond what you can service |
| Owner-occupier only | Yes — you must “live in your home for the duration of your loan with us” (Do you qualify) | No — investment lending available |
| Expected duration | Until you can refinance out | The full term if you want it |
What you actually give up
1. A higher interest rate, for as long as you stay
This is the real price of the low deposit. Keystart’s rate has historically sat above what a well-qualified borrower can get from a mainstream lender. We do not print either figure here, because a stale rate is worse than no rate. Compare them on the day: Keystart publishes every product’s variable rate and comparison rate side by side on Compare our home loans, and the RBA publishes lending rate statistics at rba.gov.au.
One thing worth checking before you accept the standard rate. Keystart’s range runs to eight products and they are not all priced the same — the Skilled Start Home Loan, for apprentices, skilled construction workers, graduates and frontline workers, is discounted below the standard variable rate (checked 7 September 2026). If you are in one of those trades, look at that product before you compare anything else.
Over a short period that gap is manageable. Over twenty years it is not, which is why Keystart itself frames the loan as a stepping stone rather than a destination.
2. Variable rates only
Keystart does not offer a fixed rate. Its own wording is that “all Keystart loans have a variable interest rate”, and all eight products on its comparison page are listed variable-only (How we calculate our interest rates and Compare our home loans, read 7 September 2026). If certainty in your monthly repayment is the thing that lets you sleep, that matters. We cover how the rate moves and what to do when it does in how Keystart interest rates work.
3. A ceiling on what you can buy
The property price cap is not a guideline. It is a hard limit, and in a market where WA land prices have been climbing it narrows your options — particularly the suburbs and the block sizes available to you.
What sets the cap is mostly which product you are on, not which region you buy in. The Shared Ownership Home Loan and the Urban Connect Shared Equity Home Loan each publish a maximum purchase price well below the Low Deposit Home Loan’s.
Region is less clear cut, and we will not pretend otherwise. Keystart’s Before you apply page says there are “higher property purchase limits in regional areas or in the State’s North West”, and that those higher limits “also have higher deposit requirements”. But driving the region selector on the Low Deposit Home Loan page through metro, regional, the Kimberley and the Pilbara moves the income limits and leaves the maximum purchase price unchanged (checked 7 September 2026). Keystart’s own two pages do not agree, so do not plan a regional purchase around a higher cap until Keystart confirms one in writing.
Either way, read the figure on the product page you are actually applying under rather than from a figure quoted here.
A second trap on that page: the loan amount selector in the Key Facts Sheet tool is not the purchase price cap. The cap is stated separately, higher up the same page.
For a house and land package one loan carries the land purchase and the builder’s progress payments, so the land and the building contract have to work as one number. Keystart does not publish how it measures total value for a build, or whether site works sit inside its maximum purchase price, so ask before you sign. A package that fits today can also stop fitting after a handful of variations. That is the single most common way a Keystart build comes unstuck, and it is covered in Keystart for house and land packages.
4. A ceiling on what you can earn
Because the income limit is a maximum, a pay rise or a partner returning to work can push a household out of eligibility between enquiry and application. If you are close to the limit, get the timing right rather than discovering it late.
The limits are set per product and per region, they are assessed on gross household income, and they move — Keystart states plainly that “these income limits are applicable for the Low Deposit Home Loan. Limits vary for each loan product.” The Kimberley and Pilbara limits are materially higher than the metro and regional ones. Read the current figures with the region selector on Before you apply and on the product page you are applying under.
5. A loan you are meant to leave
Keystart’s model assumes you refinance to a mainstream lender once you have built enough equity. That is not a catch — it is the design. But it does mean you should plan the exit at the start, not treat it as someone else’s problem in five years.
What you actually gain
You start now instead of later
The honest comparison is rarely “Keystart versus a bank today”. It is “Keystart today versus a bank in three or four years”, once you have saved a full deposit. In a market where land prices and build costs have been rising, waiting has a cost too. It is just a cost nobody sends you an invoice for.
You avoid lender’s mortgage insurance
LMI is a one-off premium that protects the lender, not you, and it is usually added to the amount you borrow — so you pay interest on it for the life of the loan. Removing it is real money, not a line. It applies across the whole range — every Keystart product is published with “no lender’s mortgage insurance” (Compare our home loans, read 7 September 2026).
You are assessed by a lender built for your situation
Keystart’s criteria were written for people the mainstream test rejects. That does not mean the assessment is soft — the servicing test is real — but it does mean a thin credit file or a single income is less likely to end the conversation.
The maths that actually decides it
Do this before you decide anything.
- Get a mainstream number. Ask a mortgage broker what you could borrow
today at a bank, with the deposit you actually have, including any LMI.
- Get a Keystart number. Use Keystart’s calculators, or ask Keystart
directly.
- Compare total cost over your realistic holding period, not over thirty
years. If you expect to refinance in three or four years, compare three or four years.
- Add the cost of waiting. If the bank option means saving for another two
years, estimate what the same house and land costs then.
- Stress test both. Add a meaningful rate rise to the variable option and
check the repayment still works.
If the numbers land close together, take the mainstream loan. If Keystart is the only way you get in this decade, the higher rate is buying you time in the market, and you refinance out when you can.
Who each option suits
Keystart tends to suit a first home buyer with a modest deposit and stable income, who fits inside the income and price caps, who is building or buying to live in, and who is comfortable with a variable rate for a few years.
A mainstream bank loan tends to suit a buyer with a deposit at or near 20%, a household income above the Keystart limit, anyone wanting a fixed rate, and anyone buying an investment property.
Neither is a decision to make alone. Talk to a mortgage broker about the loan. We are the ones who can tell you what land and what build actually fit the number they give you, and what a builder’s quote leaves out.
Frequently asked questions
Is Keystart cheaper than a bank loan? Usually not on interest rate. It can be cheaper to enter, because there is no lender’s mortgage insurance and the deposit is 2%. Compare the rates yourself on the day — Keystart’s are on Compare our home loans.
Can I refinance out of Keystart later? Yes, and that is the intended path. Timing depends on your equity and on what a mainstream lender will approve.
Does Keystart offer a fixed rate? No. Every product in the range is variable (Compare our home loans, read 7 September 2026).
Will a Keystart loan hurt my credit or my next application? No. It is an ordinary regulated home loan and a clean repayment history helps your next application.
Can I still get the First Home Owner Grant with a Keystart loan? Yes. The grant is a separate WA scheme with its own criteria and applies alongside a Keystart loan — Keystart will let you put it towards your deposit if you are building. It is a one-off payment of up to $10,000 (as at September 2026) with no income or assets test, and it only applies to a new or substantially renovated home, not an established one. It carries its own property value cap, which was reset on 7 May 2026 (WA Department of Finance, read 7 September 2026). Read the current cap there rather than from a figure quoted anywhere else.
Do you get paid if I choose one loan over the other? No. We are not paid by any lender. See how we are paid.
