House and land means buying a vacant lot and building a brand-new home, while established means buying an existing house. In WA, building attracts the $10,000 First Home Owner Grant, charges stamp duty on the land only, and avoids near-term maintenance, but takes around 12 months to complete. Established buys a finished home today at full duty.
It is the first real fork for most buyers: build it new or buy it finished. The sticker price is the loudest signal and the least useful one. Once you count grants, duty, depreciation, maintenance and the cost of waiting, the two paths separate in ways the listing price never shows.
What each path actually is
House and land is two purchases that work as one: a vacant lot, then a fixed-price building contract for a new home on it. You choose the design, the inclusions and the suburb, and the home is yours from day one with no prior wear. Established is a single purchase of a finished house in a settled street, available to move into now.
The Property Plug carries 46 new home designs priced against the real siteworks figure for 102 Perth suburbs, which is the house-and-land side. The decision below is not which is better in the abstract, but which is better for your budget, timeline and suburb.
The trade-offs, compared
The table sets the two against each other on the points that move the real cost and the real outcome, not just the headline price.
| Factor | House and land (new) | Established |
|---|---|---|
| First Home Owner Grant | $10,000 available | Not available |
| Stamp duty | On land value only | On full property value |
| Move-in | After build, around 12 months | Immediate |
| Maintenance | New, minimal for years | Often some catch-up |
| Depreciation | High, new building and fittings | Limited |
| Location | Often newer outer estates | Settled, established suburbs |
| Land content | Set by the estate lot | Often larger, scarcer |
The one cost people forget
The hidden cost of house and land is time. A new build takes around 12 months from contract to handover, and during construction many buyers pay rent and a progressively drawn construction loan at the same time. Established avoids this entirely. Budget for the overlap, because it is real money the sticker price never mentions.
This is the honest counterweight to the incentives. Building new is cheaper on duty and richer on grants, but you carry the cost of living somewhere else while it is built. A construction loan draws down in stages, so your interest grows as the home rises. For most first home buyers the grant and duty savings still come out ahead, but only if the waiting cost is in the plan from the start.
Which one suits you
Use this short framework to land on the right side.
- Do you need to move in now? If yes, established wins on timing alone.
- Are you a first home buyer? If yes, the grant, land-only duty and low-deposit schemes tilt strongly to house and land.
- Are you investing? If yes, weigh new-build depreciation and low maintenance against established land content and location.
- Can you carry rent and a construction loan together for the build? If no, that constraint may decide it for you.
To price the build side properly, read our true cost to build by Perth suburb guide and the grants explainer, then browse the designs. The numbers, not the newness, should decide it.
Add the grant and duty saving on the new build, then subtract your estimated rent plus construction-loan interest over the build period. Compare that net figure to the established option, not the two list prices.
