Here we are asking you to estimate only. It’s often hard to get an accurate estimate of your property value.
Some real estate websites such as Domain, Realestate.com.au and Onthehouse will give you an estimate. However, be aware that a bank valuer might assume a lower estimate, so it can be a good idea to make your estimate slightly lower.
If you do apply to refinance, the lender might send a valuer out to your home, so it is worth being prudent.
