Borrowers dodge refinancing mortgage to renovate homes

February 2, 2015, Sydney, Australia – Australian homeowners are dodging renovations funded by the equity in their mortgage because it’s too difficult, according to a new study by one of Australia's biggest comparison websites

The survey of more than 1,000 home owners commissioned by found that the vast majority (90 percent) have never refinanced their home to renovate. Out of those who haven’t refinanced to renovate their home, just 17 percent would consider it.

Almost three in four (73 percent) homeowners think it would be difficult to refinance their mortgage to renovate their home. In fact, 14 percent find the idea overwhelming, with women slightly more overwhelmed than men.

Michelle Hutchison, Money Expert at, said she is not surprised by the findings, given the decline in borrowers financing home loans for alterations and additions.

“Many borrowers are dodging the idea of refinancing their home to renovate because they just don’t know where to start.

“We found that the value of home loans being financed for alterations and additions averaged $352 million per month for the past five years (since January 2010). It has almost halved compared to over a decade ago, hitting a peak of almost $640 million in one month in 2003.

“It’s not surprising when our survey found that most people are in the dark with the costs and value it will add."

The survey found that more than one in three homeowners who haven’t refinanced to renovate are unsure how much it would cost, if they can afford to, how much value it would add or where to start.

Out of those who have refinanced to renovate, the vast majority (93 percent) had concerns whether they could afford to, what their mortgage repayments would be and their biggest concern was how much value it would add.

Over two in five homeowners (42 percent) are worried about rising interest rates, as unlocking equity to renovate means borrowers will have a bigger mortgage with higher repayments.

"The problem with refinancing to renovate is that every household is different. Everyone has different financial situations, mortgage sizes, equity and work needing or wanting to be completed. The amount of money people want to spend can also vary significantly.

“It doesn’t need to be overwhelming if you want to unlock equity to renovate your home. In fact, there are a few simple rules and guides to follow to ensure you will have the best outcome,” said Mrs Hutchison. tips on refinancing to renovate:

  • Work out how much equity you have: get a valuation and find out the maximum Loan-to-Value (LVR) needed for your home loan to determine how much money you have available to draw on
  • Set a benchmark for value: find out what the median house/unit price is in your area and look at similar properties recently sold in your area
  • Rule of thumb: don't spend more than 10% of the median property value. However, this can vary depending on the condition of the property
