When you’re buying property in Sydney, you’re dealing with a different scale. Prices are higher than most other Australian cities, which means your deposit needs to be bigger and your borrowing capacity gets tested more carefully. It also means the gap between what a lender says you can borrow and what feels comfortable to repay becomes something you need to think through properly.
If you’re preparing to apply for a home loan, working with a mortgage broker in Sydney can help you get clear on what’s realistic before you start making offers. You’ll see how different lenders assess your income and expenses, what deposit you actually need, and where the trade-offs between borrowing more or keeping repayments manageable are.
Why You Need a Bigger Deposit in Sydney
Most lenders want to see at least a 20% deposit if you want to avoid paying lenders mortgage insurance (LMI). In Sydney, that 20% represents a much larger amount of cash than it would in regional areas or smaller cities.
If you’re buying a property for $1.2 million, a 20% deposit is $240,000. Drop to 10%, and you’re looking at $120,000. But you’ll pay LMI, and your loan-to-value ratio (LVR) will be 90%, which can limit which lenders will approve you and what interest rates they’ll offer.
A higher LVR means more risk to the lender. That often translates to stricter assessment criteria, higher rates, or both. Some lenders cap LVR at 80% for certain postcodes or property types, which means you can’t borrow as much as you’d need without a bigger deposit.
This is where talking to a mortgage broker in Sydney helps. They can show you which lenders accept higher LVRs for your situation and what the LMI cost would be. They can also help you decide whether it makes sense to wait and save more or go ahead with a smaller deposit and factor the insurance into your budget.
Working With a Mortgage Broker in Sydney to Understand Borrowing Capacity
Borrowing capacity is the maximum amount a lender will let you borrow based on your income, expenses, debts, and a few other factors. Different lenders assess this differently. One bank might approve you for $850,000. Another might stretch to $920,000. A third might cap you at $780,000.
Differences are influenced by how each lender calculates your expenses, applies interest rate buffers, and treats things like HECS debts, rental income, or irregular pay.
If property prices are higher, those variations become more noticeable. A $70,000 difference in borrowing capacity could be the difference between affording the type of property you want or needing to adjust your search.
A mortgage broker can run your details through multiple lenders and show you where your capacity sits across the panel. You’ll see which lenders are likely to approve you for more, which ones assess things more conservatively, and what you might need to change (paying down a credit card, for example) to improve your borrowing power.
Maximum Borrowing vs Comfortable Repayments
Borrowing capacity tells you the ceiling. Comfortable repayments tell you where you want to be.
Just because a lender says you can borrow $900,000 doesn’t mean that’s the right number for you. Lenders assess affordability using a test rate that’s higher than the actual rate you’ll pay—usually around 3% above the loan rate. That buffer is there to make sure you could still afford repayments if rates went up.
But the lender’s test doesn’t know your life. It doesn’t account for school fees, planned renovations, or whether you want breathing room for holidays and savings. The maximum you can borrow might leave you stretched if anything changes—a pay cut, a rate rise, or unexpected expenses.
This is where you need to be honest with yourself about what monthly repayment feels manageable. Use a repayment calculator to see what different loan amounts would cost you each month, then compare that to your actual budget.
If you borrow $800,000 instead of $900,000, your repayments drop by several hundred dollars a month. That difference compounds over time and gives you a buffer if things get tight.
Speak to a mortgage broker in Sydney if you want to talk through how much to borrow vs how much you could borrow. They’ll help you see the trade-offs and work out what leaves you in a solid position long-term, not just at settlement.
How Lender Policy Can Vary by Property Type
Not all properties are treated the same by lenders. Apartments in high-density areas, properties with commercial zoning, or homes in certain postcodes can trigger different lending rules.
Some lenders cap LVR at 70% or 80% for apartments in buildings over a certain height or with more than 50% non-owner-occupied units. Others won’t lend on studios or serviced apartments at all. These restrictions aren’t always obvious until you’re partway through an application.
If you’re buying an apartment or a property type that differs from the typical house-and-land scenario, it’s worth checking what the lending rules look like before you commit. A broker can tell you which lenders accept the property type you’re looking at and what LVR caps or rate loadings might apply.
Getting Clear on What You Can Actually Borrow
Sydney’s property market rewards preparation. Before you start attending auctions or making offers, get clear on your borrowing capacity, your deposit, and what you’re comfortable repaying.
A mortgage broker can help you see your options across multiple lenders, explain how different policies affect your situation, and give you a realistic view of what’s within reach.
If you want to get started, you can pre-qualify online to see what you might be able to borrow or book a consultation to talk through your plans with someone who understands how Sydney’s property prices affect borrowing decisions.
Frequently Asked Questions
How much deposit do I need to buy property in Sydney?
Most lenders want 20% to avoid lenders mortgage insurance, but you can apply with as little as 5-10% depending on the lender and your situation. The trade-off is higher costs and stricter lending criteria.

Can a mortgage broker help me borrow more?
A broker can show you which lenders are likely to approve you for higher amounts based on how they assess income and expenses. They can also help you see what changes (like paying down debts) might improve your borrowing capacity.
