Bridging Loans: Buying Before You Sell
A bridging loan covers the gap when you buy your next home before the old one sells. Useful, but the timing and the interest need managing carefully.

Finding your next home before your current one has sold is a common bind. A bridging loan is designed for exactly this, giving you short-term finance to complete the purchase while you sell. It solves a real problem, but it also carries real risk if the sale takes longer or fetches less than expected, so it pays to understand how it works before relying on one.
A bridging loan temporarily finances your new purchase before your existing home sells. The lender combines both loans into a peak debt, charges interest across the bridging period (often capitalised so you make few or no repayments), and once your old home sells, the proceeds reduce the debt to a manageable end debt that becomes your ongoing loan. It works best with a realistic sale price and a clear timeframe.
How a bridging loan works
When you buy before selling, the lender provides finance to complete the new purchase while still holding your existing mortgage. For a defined bridging period, commonly six to twelve months, you have access to both properties. When your current home sells, the sale proceeds pay down the combined debt, and you are left with a standard loan on your new home.
Most bridging loans capitalise the interest during the bridging period, meaning it is added to the loan rather than paid monthly, so you are not stuck making two full repayments at once.
Peak debt and end debt
Two terms matter here. Peak debt is the total you owe during the bridge: your existing loan plus the new purchase plus costs. End debt is what remains after your old home sells and the proceeds are applied. The lender assesses whether you can service that end debt as your ongoing loan, and wants comfort that the sale of your current home will realistically cover the gap.
The larger your equity in the existing home, the smaller and safer the end debt, which is why bridging suits people with substantial equity.
What it costs
Bridging finance generally carries interest on the full peak debt for the bridging period, and because that interest is often capitalised, it compounds. The longer your old home takes to sell, the more it costs. There may also be valuation and application fees on the new lending. It is not inherently expensive if the bridge is short, but a slow sale can add up quickly.
Interest accrues on the whole peak debt until your home sells. A sale that drags on, or a price well below expectation, directly increases your cost and your end debt. Price your existing home to sell, not to dream.
The risks to manage
The core risk is that your existing home sells slowly or for less than you hoped, leaving a larger end debt than planned. Some lenders set a maximum bridging term, and if you exceed it the arrangement can become costly or need renegotiating. This is why a realistic sale strategy, and a buffer, matter so much. Bridging rewards borrowers who have real equity and a saleable property, and punishes optimistic assumptions.
Is bridging right for you
Bridging suits you if you have found the right next home, hold solid equity in your current one, and your existing property is likely to sell within a reasonable timeframe. If your equity is thin or the market is slow, the alternative of selling first, or negotiating a longer settlement, may be safer. A broker can compare bridging against those alternatives and stress-test the numbers. Sense-check your ongoing loan with the repayment calculator and borrowing power calculator.
Common questions
How does a bridging loan work?
It provides short-term finance so you can buy your next home before your current one sells. The lender combines both loans into a peak debt and usually capitalises the interest during the bridging period. When your existing home sells, the proceeds reduce the debt to an end debt that becomes your ongoing loan.
What is peak debt and end debt?
Peak debt is the total you owe during the bridge: your existing loan plus the new purchase plus costs. End debt is what remains after your current home sells and the proceeds are applied. The lender must be satisfied you can service the end debt as your ongoing loan.
Are bridging loans expensive?
Not necessarily if the bridge is short. Interest accrues on the full peak debt for the bridging period and is often capitalised, so it compounds. The longer your existing home takes to sell, the more it costs, which is why a realistic sale timeframe and price matter.
Do I make repayments during the bridging period?
Often not in full. Many bridging loans capitalise the interest, adding it to the loan rather than requiring monthly payments, so you are not making two full repayments at once. The accrued interest is then cleared when your existing home sells.
Who should use a bridging loan?
It suits borrowers who have found their next home, hold solid equity in their current one, and expect it to sell within a reasonable timeframe. If equity is thin or the market is slow, selling first or negotiating a longer settlement may be safer.
