The mechanics of bridging loans

Bridging finance is a short term loan designed to cover the period between buying a new property and selling your existing one. It essentially combines your current mortgage and the new mortgage into one large debt, known as the 'peak debt'. During the bridging period, which usually lasts between six to twelve months, you generally only make interest payments. In some cases, these interest payments are capitalised, meaning they are added to the loan balance rather than paid out of pocket. Once your original property sells, the proceeds are used to pay down the peak debt, leaving you with a standard 'end debt' on your new home.

Not all lenders offer bridging finance, and those that do have strict criteria. They will assess your ability to service the 'end debt' and will often require a significant equity buffer. The lender will also want to see a clear plan for selling your current home, including a realistic listing price and a timeline. In Victoria, lenders may be more cautious in slower markets where properties take longer to sell. If your home does not sell within the agreed bridging period, the lender may exert pressure on you to reduce your asking price or, in extreme cases, take control of the sale process.

Costs and interest rates for bridging

Bridging loans typically carry higher interest rates than standard home loans. This is because they represent a higher risk to the lender. Additionally, because the interest is often calculated on the 'peak debt' (the combined value of both mortgages), the interest can accumulate very quickly. For example, if you have a 400,000 dollar mortgage and buy a 900,000 dollar home, your interest is calculated on 1.3 million dollars until your first home sells. Even a few months of this can add significantly to your total debt. You should also check for application fees, valuation fees, and any discharge fees associated with the bridging arrangement.

  • Calculate potential interest on the peak debt
  • Verify the maximum bridging period allowed
  • Check if interest is capitalised or paid monthly
  • Assess the impact of a lower than expected sale price
  • Confirm valuation fees for both properties

Peak Debt Warning

The peak debt is the most expensive phase of an upgrade. Always simulate what happens if your sale takes twice as long as expected.

Qualification and exit strategies

To qualify for a bridging loan, you generally need to have at least 20 to 30 percent equity in your current home. Lenders need to be certain that the sale proceeds will be sufficient to bring the final loan down to a manageable level. You will need to provide a Contract of Sale for the new property and, eventually, for your existing property. If you are buying at auction, you should have the bridging loan pre-approved before you bid. It is vital to have a 'Plan B'. If your home does not sell, could you rent it out? Would the rental income cover the bridging interest? Lenders will often ignore potential rental income when assessing bridging applications.

The Capitalised Catch

A buyer chooses to capitalise their bridging interest. After six months of their home being on the market, they find that their loan balance has grown by 30,000 dollars. This reduces the amount of money they have available for their new home's renovations.

In Victoria, the market can change rapidly. A bridging loan requires you to be a proactive seller. You cannot afford to wait for the 'perfect' price if the market is trending downwards. Your lender will likely require updates on the sale process and may have the right to request a new valuation if the process drags on. Being realistic about your property's value from the start is the best way to ensure your bridging experience is a successful transition rather than a financial burden. Always discuss the terms and conditions with your legal advisor to understand your obligations under the loan contract.

Finally, consider the alternative of a 'relocation loan' which some lenders offer. These are similar to bridging loans but may have different structures regarding how interest is charged or how the transition is managed. Regardless of the name, the principle remains the same: you are borrowing against two properties at once. The goal is to make that period as short as possible. Use every tool at your disposal, including professional styling and targeted marketing, to ensure your current home sells quickly and for the best possible price to minimize your time in the bridging phase.
