What Is Peak Debt in a Bridging Loan? (Explained for Australian Borrowers)

If you're considering a bridging loan, one of the most important concepts to understand is peak debt.
Peak debt refers to the maximum total loan amount you owe during the bridging period, when you temporarily hold both your existing property and your new purchase.
This is a critical number because it determines:
how much you can borrow
your loan-to-value ratio (LVR)
the overall risk from a lender’s perspective
To fully understand how this works, it’s important to first understand how bridging loans are structured. For a full breakdown, see How Bridging Loans Work.
How Peak Debt Works in Practice
Let’s break it down with a simple example:
Existing property value: $1,000,000
Existing mortgage: $400,000
New purchase price: $900,000
During the bridging period, your lender combines both debts.
Your peak debt would be:
Existing loan: $400,000
New loan: $900,000
Total peak debt: $1,300,000
This is the highest level of debt you will carry, even though it is only temporary.
Why Peak Debt Matters to Lenders
Peak debt is one of the most important metrics lenders assess when structuring a bridging loan.
1. Loan-to-Value Ratio (LVR)
Lenders assess peak debt against the combined value of both properties.
If your peak LVR is too high, the deal may not proceed or may require additional security.
2. Exit Strategy
Private lenders focus heavily on your exit strategy, typically:
selling your existing property
refinancing once your position stabilises
If your peak debt cannot be comfortably reduced, the deal becomes higher risk.
3. Interest Structure
Most bridging loans involve capitalised interest, meaning:
no monthly repayments
interest is added to the loan balance
This increases the total debt during the term, making peak debt even more important.
What Happens After the Sale? (End Debt Explained)
Many borrowers use this structure when they want to buy a property before selling. Once your existing property is sold, your loan reduces significantly.
This is known as end debt.
Example:
Peak debt: $1,300,000
Sale proceeds: $1,000,000
Remaining loan (end debt): $300,000
This is the amount you either:
refinance, or
keep as your ongoing loan
How to Reduce Your Peak Debt
There are several ways to improve your position:
Contribute savings toward the purchase
Sell your existing property sooner
Purchase below your maximum borrowing capacity
Use additional security if available
Each of these reduces risk and improves lender appetite.
Peak Debt vs End Debt: Key Difference
Peak Debt = highest debt during the bridging period
End Debt = remaining debt after your property is sold
Understanding this distinction is critical when structuring your loan correctly.
When Peak Debt Becomes a Problem
Peak debt can create issues if:
your LVR exceeds acceptable levels
your property takes longer to sell
market conditions change
your exit strategy is unclear
This is why working with experienced brokers is critical to structure the deal correctly from the outset.

FAQs
What is peak debt in a bridging loan?
Peak debt is the total amount you owe during the bridging period when both properties are held.
How is peak debt calculated?
It is calculated by adding your existing loan balance and the new purchase loan, plus any capitalised interest and fees.
What is a good peak LVR?
Most lenders prefer peak LVRs below 70–75%, depending on the strength of the deal.

What happens if my property doesn’t sell?
Lenders will typically work with you on an exit strategy, such as refinancing or managed sale.
