The DTI lending cap and what it means for property in 2026

Mortgage brokers have seen a few regulatory changes come through over the years. Through our 26 years in business, we’ve seen many different attempts to alter the playing field, from minor tweaks to monumental shifts.

The new ruling on debt-to-income caps falls more towards the latter.

Anyone with an interest in property has likely heard about the anticipated crackdown on risky lending and tighter borrowing rules proposed by APRA, the Australian Prudential Regulation Authority. While that is definitely the goal of the Australian financial services industry regulator, it’s not clear what that means for property owners, investors and anyone looking to make financial decisions in 2026.

APRA, the body that regulates Australian banks, introduced a cap on high-DTI lending. “DTI” stands for debt-to-income ratio. It basically means, how much someone owes compared to how much they earn.

Under the new rules, banks can only lend 20 per cent of their new mortgage book to borrowers with a DTI of six or higher. That means someone earning $200,000 per year who wants to borrow more than $1.2 million in total debt falls into the restricted category.

It’s worth noting, this doesn’t mean anyone will be ‘banned’ from borrowing. It’s about being classified in a category which has limits on what banks and lenders can service. The finance tap hasn’t been turned off, it’s just got a few more kinks in the hose.

APRA brought this in because high-DTI lending had started creeping up, particularly among investors. When interest rates dropped through 2025, credit growth accelerated and the regulator saw early signs of risk building in the system.

They decided to act before problems developed rather than after. For anyone who believes in stable property markets, that’s actually good news.

So who does this effect?

Any Investors with existing property debt should definitely take a look at the new ruling. Investors typically carry higher DTIs because they’re accumulating assets. Someone with a $500,000 home loan and a $400,000 investment loan, earning $180,000, is already at 5x DTI. There’s not much room before hitting the restricted category.

Another situation which could stray into this territory is high earners buying in an expensive area. And in Sydney in 2026, that’s going to apply to a lot of people. Sydney property prices don’t care about anyone’s DTI. A couple earning $280,000 who need $1.9 million to buy in their preferred suburb is looking at a DTI of 6.8. That’s above the threshold.

One which might surprise most is first home buyers with no existing debt. This category will likely be less affected than they think. Someone earning $110,000 who wants to borrow $550,000 for a unit has a DTI of 5. They’re under the threshold entirely.

One interesting wrinkle is new home buyers. The good news, they’re exempt. APRA carved out loans for new dwelling construction and purchases of newly built homes to encourage housing supply. The DTI cap doesn’t apply here.

Another good thing is for those using bridging finance to upgrade, as they will also be exempt. The temporary overlap where someone owns two properties during a move doesn’t count toward the high-DTI limit.

The unlikely path to more competition

In a roundabout way, the new DTI cap policy creates an interesting competitive dynamic.

Banks have a limited allocation of high-DTI loans. Once they use it up, they stop approving high-DTI applications until the next quarter. That means borrowers in the restricted category are competing not just against lending criteria, but against each other for limited spots.

Who wins that competition? Generally, the cleanest applications. The best-documented borrowers. The people who can demonstrate strong credit histories, stable income, solid asset positions. Usually, the ones with experienced advisors helping them navigate this new landscape.

In other words, it’s the borderline cases who will feel the squeeze. Strong borrowers who also happen to have a high DTI will likely still get through.

This also means lender choice matters more than ever. Different banks manage their allocations differently. Some are conservative and keep plenty of buffer. Others run closer to the limit. A loan that gets declined at one bank might sail through at another. Same borrower, same application, different outcome.

That’s where working with a broker who knows the market becomes genuinely valuable. They see which lenders have appetite and which ones are constrained. They know where to send an application to maximise the chances.

When you know the lending market like we do, arbitrage opportunities like this become obvious.

Getting approved in 2026

So how do you win and make sure this new policy helps, not hinders any aspirations to build wealth through property?

From here, it will be important to know your Debt-to-Income ratio before doing anything else.

This is step one and unfortunately too many people skip it. Add up all debts, including your home loan, car loan, personal loans, credit card limits (not balances), HECS, buy-now-pay-later accounts. Divide by gross annual income.

That number is the DTI. Know that number.

Under 5 means good shape. Between 5 and 6 means approaching the threshold. Over 6 means thinking carefully about how you approach lending.

Clean up unnecessary debt

This is the clearest and most direct impact on your DTI number. Credit cards are the biggest culprit. Banks count credit limits, not balances. That card with a $20,000 limit that never gets used? It’s costing $20,000 in borrowing capacity.

Close unused accounts. Reduce limits on cards in use. Pay off small debts cluttering up the liability statement.

Every dollar of debt eliminated directly improves DTI. Good debt hygiene is always important but with new policies like this altering the landscape, this kind of discipline now takes a much higher priority.

Income matters

DTI has two components: debt and income. The ratio can be improved by reducing debt or increasing income.

Income is harder to change, but it’s worth examining carefully. Is all assessable income being captured? Rental income, bonus structures, overtime, side businesses with tax returns to support them, all of these sources can potentially be included.

Is the employer’s letter showing the most recent salary? Has there been a raise that isn’t reflected in the last application? Are there two incomes that could be on the application instead of one?

Sometimes a few thousand dollars of additional assessable income makes the difference between a 6.1 and a 5.9 DTI. That’s the difference between who will lend and who won’t.

Use the new-build exemption strategically

This is a recurring theme because it’s genuinely useful. Buying or building a new dwelling means the DTI cap doesn’t apply.

However, not everyone should buy new just because of this rule. New builds have their own considerations including construction timelines, developer risk, the reality of living in a developing area while infrastructure catches up.

But for anyone genuinely open to both established and new properties, the regulatory environment now gives new builds an edge from a lending perspective. That should factor into decision-making.

Get application timing right

Banks measure high-DTI lending quarterly. In theory, early in a quarter there’s more capacity. Late in a quarter, banks might be watching their numbers and tightening up.

In practice, this varies by lender. Some manage their allocation smoothly throughout the quarter. Others genuinely do run tight toward the end.

This is where a good broker can give a read on current market conditions. It’s the kind of granular intelligence that makes professional advice worth the conversation.

Prepare a bulletproof application

When banks have limited high DTI capacity, they get picky about who receives it. A well-documented, cleanly presented application beats a messy one.

Gather payslips, bank statements, tax returns and asset summaries before applying. Anticipate questions and have answers ready. Make it easy for the assessor to say yes.

This has always been good practice. Now it’s essential practice.

The right home needs the right loan

This shift is a significant one, but it doesn’t alter the fact that property is still one of the most reliable vehicles to build real wealth for the long-term.

The people who build wealth through property aren’t the ones with perfect circumstances. They’re the ones who adapt their plans to the circumstances they have.

The DTI cap is a new circumstance. It changes the landscape, but it doesn’t prevent savvy investors and homeowners from taking the next step in 2026.

People will continue to successfully purchase property. Some will be under the threshold entirely. Some were over it but got through because they applied to the right lender at the right time with a strong application. Some bought new builds and avoided the cap altogether.

All of them understood their position, made informed decisions, and worked the system intelligently.

That’s possible for everyone.

Time to take action

Wherever you are on your property journey, the key next step is to find out where you actually stand.

Get DTI calculated properly. Understand which category applies. Map out what could realistically be borrowed, from which lenders, under current conditions.

This approach is a great planning exercise to kick off the year. Real wealth is built through good decisions, made over time. Good decisions can’t be made without good information.

The Sydney property market is one of the most vibrant and dynamic markets in the world. It may not be easy, but it can be the vehicle which builds the future you want for you and your family.

People will continue to buy, sell and build property. The question isn’t whether it can be done. It’s about having the right experts by your side to make the good decisions and use these opportunities to your advantage.
