Before You Sign a Builder Contract, Ask These 4 Questions (Or Risk a Two-Year Delay on a Home That Should Take Eight Months)

If you’re about to sign a building contract, there’s something most homeowners never think to check: whether your builder actually has the capacity to start and finish your home when they say they will.

It pains me to say it, but I’ve met families who were contract number 57 in a builder’s queue and had no idea. They were told construction would start in a few months, and eighteen months later they were still sitting with an empty block.

By the time they realised something was wrong, the contract was signed, the deposit was paid, and the leverage was gone.

So before you agree to anything, ask these four questions. They’ll tell you quickly whether a builder has genuine capacity for your build, or whether you’re about to become another number.

It takes about fifteen minutes, and it may save you two years of waiting and tens of thousands of dollars.

 

Question #1: How Many Homes Have You Got Signed Up That Start Before Mine?

 

Most builders won’t see that one coming, so pay attention to how they answer it.

What you’re trying to find out is simple. If they’ve got 55 homes ahead of yours, when does your build actually start, and when does it actually finish?

A straightforward single-storey home should take somewhere around eight months to build. Complex projects, two-storey homes, sloping blocks and acreage, can run to double that or more. So if you’re number 55 on someone’s list, do the math. That’s a long time to be paying rent on a block you already own.

A builder who knows their business can tell you:

• How many projects sit ahead of yours
• How start dates are sequenced
• What can move those dates, and by how much
• A realistic start and finish date for your build

If they can’t answer those clearly, keep your options open until you find a builder who can.

 

Question #2: How Many Homes Are You Actively Building Right Now?

 

This one’s about this week, not last year’s pipeline.

Every active build draws on the same pool of trades, supervisors and scheduling capacity. There’s only so much of each to go around. When that pool gets stretched, your job starts absorbing someone else’s problems. Their delay pushes your trade. Your slab gets rescheduled. Suddenly you’re two months behind for reasons that had nothing to do with you.

I’ve sat with families who couldn’t understand why their build kept stalling. The builder was always apologetic and always had a reason. What never came up was the thirty other jobs running at the same time with the same supervisors.

I run three, four or five homes under construction at once, maximum, depending on the type of build. I also work to a limited number of construction slots each year, which caps how many families I can help at any one time. Both numbers are deliberate. They’re the reason I can start sooner and finish sooner, because I’m not spread thin across a hundred sites.

The builders worth trusting are the ones who:

• Know exactly where their limit is
• Can tell you who is supervising your site specifically
• Hold that line even when the pressure to say yes is real

 

Question #3: Who Decides When You Stop Taking On New Projects?

 

This is the question that tells you who’s actually running the business.

In a lot of building companies, sales and construction operate separately. Sales has targets, and it doesn’t always know what’s already happening on site. So contracts get signed, promises get made, and the construction team finds out later.

Selling a home might take a couple of weeks through a display home. Building one takes months. That gap is where the trouble starts, because there’s a hard limit on what an operations team can physically deliver, and a sales team paid on volume has no reason to respect it.

When a builder is full, they’re full. Not every builder is willing to say so, especially when the sales team is having the best year of their life selling homes like hot cakes.

We saw exactly how that plays out after COVID. Builders signed contracts at 2021 prices and didn’t break ground until 2023. By then costs had jumped around 40 per cent. Materials cost more, labour cost more, and the margins they’d counted on had gone. Some of those builders couldn’t finish what they’d started.

The people left waiting were families who’d paid deposits, given notice on rentals and told their kids which school they’d be starting at. When the builder went under, the deposit went with it. Some were left with a half-built home and no way to finish it. Others had contracts cancelled after years of waiting and were back at square one, except the build now cost twice as much.

Most of those builders failed because they got greedy. They didn’t know when they were full, or they weren’t prepared to sit down with their sales team and say they weren’t taking on anything new for the next twelve months.

So ask them directly:

• How do you decide when a new project can realistically begin?
• What has to happen internally before you take on another build?
• Who makes the final call to say we’re full?

“We’re full for the next twelve months” is an answer you can work with. It’s honest, and you can plan around it. A builder who says yes without the capacity to back it up will cost you far more than the contract price ever suggested.

 

Question #4: What Happens to My Price If Costs Rise After I Sign?

 

Most people don’t ask this one. They see the number at the bottom of the contract and assume it’s settled. It isn’t always.

When a build gets delayed, even for reasons that have nothing to do with you, it moves into a new cost cycle. Materials become more expensive, products change, and when the builder’s margin disappears they come back mid-build asking for more money just to finish the job. 

I’ve seen builders asking for an extra $50,000 to $100,000 from families who were already borrowing to their limit, and banks weren’t lending more just because a builder’s costs had blown out. Those families were stuck.

This is also where a shorter build works in your favour. The less time between signing and handover, the less room there is for the market to move underneath your contract. An eight-month single-storey build carries far less of that risk than a project running two years.

So before you sign anything, make sure you understand:

• Whether the contract price is fully fixed
• Under what circumstances it can change
• How and when materials are secured before work begins
• What protections you have if supply costs move after you’ve signed

When a builder loses control of their schedule, the pricing usually follows. By the time they’re calling you mid-build, the problem has been developing for months. You just didn’t know about it.

 

One Last Thought…

 

The most honest answer a builder can give you is sometimes ‘no.’

No, we’re full right now. No, we can’t start when you need us to. No, we can’t take on another build without letting down the families we’ve already committed to.

A builder who turns work away understands what’s at stake when they say yes. That’s exactly who you want building your home.

It’s better to disappoint someone now than to disappoint them constantly for the next two years. The builder who says yes to everyone and works out the details later is the one to be wary of.

 

Before You Sign Anything, Know What You’re Agreeing To

 

Capacity is one of the ways a build goes sideways. The type of build is another. Earlier I mentioned that complex projects, two-storey homes, sloping blocks and acreage, can run to double the timeframe of a standard single-storey build. That’s not just a scheduling problem. It’s where costly mistakes tend to creep in too.

That’s why I put together this guide:
