The pros and cons of buying off-the-plan: an honest look

Buying a home before it’s built has real upsides and a few things worth knowing. Here’s both.

Off-the-plan can feel like a big leap. You’re choosing a home from a floorplan, renders (the computer-generated images of the finished home) and a display suite (the furnished showroom home), then waiting for it to be built. For plenty of people, that’s exactly what makes it appealing. For others, it’s what makes them nervous.

Both reactions are fair. So here’s a straight look at what’s great about buying off-the-plan, what to keep an eye on, and how to handle each.

The pros

A brand-new home, built to today’s standards

Nobody has lived in it before. Everything is new: the kitchen, the bathrooms, the appliances, the flooring. New homes are also built to current energy and safety standards, which in everyday terms means better insulation, more efficient heating and cooling, and fewer surprises. You’re not inheriting someone else’s repairs.

Time to get ready

Between signing the contract and settlement (the day the sale completes and the home becomes yours), you typically have somewhere between 12 and 24 months. That’s time to keep saving, to sell or prepare your current home, to get your finances in shape, and to plan your move without rushing. You pay a deposit upfront (usually 5-10% of the price), and the rest isn’t due until the home is finished.

Today’s price, locked in

You agree the price when you sign. If values in the area rise while your home is being built, you’ve bought at yesterday’s price. (More on the flip side below.)

More choice

Buying early often means first pick of the homes in a development: the better floor, the northern light, the corner position. Many developments also let you choose finishes, like colour palettes or flooring, before the build locks in. It’s a chance to make a home feel like yours from day one.

Possible savings on stamp duty

Stamp duty is a tax your state government charges when you buy property. Several states offer stamp duty concessions or exemptions for new homes and off-the-plan purchases. The rules vary a lot depending on where you’re buying and your situation, so check what applies to you before you sign.

Less to fix in the early years

New homes come with warranties. Most include a defect period (often around 90 days) where the developer fixes anything that comes up after you move in, plus structural warranties, which are longer-term protection for the main structure of the building. Early maintenance costs tend to be low too.

Extra tax benefits if you’re renting it out

If you plan to rent the home out, a brand-new property can offer greater depreciation deductions than an older one. In plain English, that’s a tax deduction for the natural wear and tear on the building and its fittings. An accountant can tell you what that looks like for your situation.

The cons (and how to handle them)

You can’t walk through it first

You’re buying from plans, so what you see won’t be exactly what you get. Renders and display suites can be a great way to get a sense of your new space, but they aren't a promise.

How to handle it: Read the specifications document (the list of everything included, from flooring to tapware) alongside the visuals. If something matters to you, make sure it’s in the contract.

The wait is long

Eighteen months or more is a long time, and life moves on. A new job, a growing family or a change of plans can all happen between signing and settling.

How to handle it: Go in with a bit of flexibility, and keep in touch with your mortgage broker (who helps arrange your home loan) and your solicitor (the legal professional who handles the paperwork when you buy a property) throughout the build. Know what your contract says about timing, including the sunset clause (the date by which the development must be completed).

The market can move

Values can rise while you wait, but they can also soften. If the home is valued below your contract price at settlement, your lender may lend less, and you may need to find extra cash to complete the purchase.

How to handle it: Keep a savings buffer while the home is being built. Buying in a location you genuinely love is a steadier foundation than trying to time the market.

Your finance is checked again before settlement

Your lender does its final assessment close to settlement, not when you sign. Interest rates, lending rules and your own circumstances can all shift in the meantime.

How to handle it: Try to keep your finances steady during the build. That means being careful with new debt, big purchases and job changes where you can. And check in with your broker well before settlement, not the week before.

Build timelines can shift

Weather, supply issues and approvals can all push a completion date out. Delays happen, though big ones are less common with experienced developers.

How to handle it: Ask for a realistic timeframe, not just the best-case date. Research the developer’s track record and, if you can, visit something they’ve already completed.

The contract has a lot in it

Off-the-plan contracts are longer and more detailed than most, because they cover a home that doesn’t exist yet. They cover things like how materials can be substituted and what happens if completion is delayed.

How to handle it: Have a solicitor or conveyancer (a specialist in property paperwork) go through it with you before you sign. It’s one of the best investments you’ll make in the whole process.

So, is it right for you?

Off-the-plan suits a lot of people, but it’s not the answer for everyone. If you need to move in next month, or you’d rather walk through your exact home before committing, an established home might fit better. If you like the idea of a brand-new home, time to prepare and a say in how it looks, it’s well worth a closer look.

Whichever way you lean, the best decisions come from knowing the whole picture. Ask plenty of questions, get good advice, and take your time.
