These are the dodgiest things I’ve seen property developers do in 2026.
The sort of things they do to pump up sales that blur (and cross) the lines of what’s ethical and, sometimes, legal.
I’ve been in property long enough to know that when the market gets tough, the behaviour gets dodgier.
To be clear, most developers are hardworking people trying to build good houses. But a small minority cut corners, stretch the truth and deliberately operate in legal grey areas.
And when that happens, investors suffer. They get drawn into properties based on assurances that don’t pass the sniff test. Or get investor’s remorse and wish they’d never bought.
In this article, I’ll walk you through the dodgiest things I’ve seen developers do recently. That way you can avoid the bad behaviour.
Not every developer plays fair. Before you buy, check the numbers, get promises in writing, and make sure the deal works without the hype.
Some developers are now verging on the line of giving investment advice. Except, they don’t have the right license to give that advice.
They’ll present cash flow projections, yields, and return forecasts. Sometimes they’ll even say the property is a “strong investment.”
Technically, they can do this ... as long as they include a disclaimer saying something like:
“We are not financial advisers. Please seek independent advice.”
But there’s an obvious issue … they’re developers. Not investment experts.
From my experience, developers’ cashflow projections often have obvious errors.
And while there might be a disclaimer that says, ‘not financial advice’. The language in these emails would lead most people to believe they’re getting advice.
What you can do to protect yourself: Check if the person (or company) you’re talking to is on the Financial Service Providers Register.
Properties on Airbnb tend to get higher cashflow compared to if that same property was a long-term rental.
That’s why some developers inflate the financial returns of their properties by only looking at a property as an Airbnb.
This causes multiple issues. Firstly, they often forget about GST. If your Airbnb earns more than $60,000, you need to be GST-registered.
That can create complications years later when you sell. Depending on how the property was structured, you may face a 13%+ tax bill on the increase in value of your property.
By then the salesperson who showed you the Airbnb projections is long gone, and you’re left explaining the situation to IRD.
That’s risky, which is why investors should check if the property stacks up as a long-term rental. (Not just as an Airbnb).
That’s because Airbnb income is less stable than weekly rent. It depends heavily on tourism demand and seasonal travel.
Second, there’s more regulation. Councils can tighten the rules. Some apartment buildings can ban short-term letting altogether.
What you can do to protect yourself: Always model an investment as a long-term rental. Treat Airbnb as a bonus.
More recently, I’ve seen developers market properties as if the property is guaranteed to go up in value.
One marketing email I read claimed: “By the time this property settles, you will have made $32,000.”
To be fair, property prices can go up while a property is being built. But, they can go down too.
The developer can’t guarantee that your property will definitely go up in value. And if the property drops in value before settlement, it's your problem – not theirs.
They’re speculating and pretending to be certain.
I’ve also heard salespeople say things like:
“If you can’t settle the property, don’t worry – we’ll just resell the property.”
Unless that promise is written in your contract, it means nothing.
Developers don’t fall under the Real Estate Authority or the Financial Markets Authority.
They are private sales. So the average buyer needs to be especially careful when working directly with developers.
What you can do to protect yourself: If you are relying on a specific claim about property prices rising, get it in writing.
When you buy a New Build property in New Zealand, the Building Act (2004) gives you two protections:
Most developers honour these obligations. But not all.
Recently, some investors contacted me about a broken septic tank system in their development. The cost to fix it was huge. And the investors didn’t want to shell out thousands of dollars when the septic tank was basically still new.
Initially, the developer refused to cover the cost.
The owners banded together and obtained an independent engineering report. This confirmed the system wasn’t compliant to begin with.
Eventually, the issue was resolved. But the developer made the owners sign a confidentiality agreement. This banned them from talking about it.
Think about that – the developer screwed up, got caught, and then made the owners promise not to tell anyone.
It’s a reminder that while the legal protections exist, there’s always someone trying to dodge the law.
Thankfully, the Disputes Tribunal limit increased from $30,000 to $60,000 in January 2026.
That means you can more easily take a developer through the justice system when they do something wrong.
What you can do to protect yourself: Know your rights, and don’t be afraid to go to the Disputes Tribunal.
Sometimes the dodgiest behaviour isn’t the property, it’s how the deal gets pushed through.
I know of a young buyer who made a low offer on a New Build property listed at around $800,000. She signed a sale and purchase agreement (the standard process), and sent her offer in.
After some back-and-forth negotiations, the developer counter-offered at a higher price. So, she walked away.
A few days later, she received an email congratulating her on her successful purchase. The developer had taken her original contract and signed it to accept the offer. That meant she’d have 10 days to do all her checks before buying the property for certain.
Then, the developer’s lawyers said the due diligence period had expired ... and tried to say that the contract was now binding. She’d have to buy the house.
The family sought legal advice and pushed back. They said that the contract wasn’t valid. Eventually the developer (and their lawyers) gave in.
But the experience shook the buyer.
What you can do to protect yourself: Make sure you (or your lawyer) cancels an offer after it has been rejected
Some developers dress deals up with incentives.
Things like:
These can have benefits, but you need to read the fine print carefully.
For example, a property might advertise a rental guarantee of $820 per week for two years.
But actually, once that guarantee expires, the rent drops by over $100 to the market rate. And the harm is that investors think they’re getting a good deal, but actually it was just a temporary sugar hit.
That doesn’t mean every developer using these incentives is dodgy.
But you should always ask the key question: Does the deal still make sense without the incentive?
What you can do to protect yourself: Ignore rental guarantees from developers and always get a rental appraisal before you buy.
The good news is, most of these examples are avoidable.
If someone shows you numbers based on Airbnb income, run the same deal as a normal rental.
If the projections assume 7% growth every year, ask what happens if growth is half that. And if someone says “don’t worry, we’ll sort it out if something goes wrong,” … ask for it in writing.
Most importantly, get independent advice from people who aren’t employees of the developer. It could be your financial adviser, like the team at Opes, a mortgage adviser or your lawyer.
And if something doesn’t feel right, walk away.
Remember, you always have the disputes tribunal in your corner if you need them.
Because the reality is this: good developers won’t pressure you. And the ones who do pile the pressure on … have just told you everything you need to know.
