Please be aware that if you search online for a property valuation in Rosebud, or a property valuation in Dromana etc. you will see a large number of real estate agents appear in the results. They are not licensed property valuers, and cannot undertake valuations on their own. Being listed in this category is a strategy to try and initiate contact with you.
When searching for a valuer it is firstly important to ensure they are current member of the Australian Property Institute, and that they hold a current certified practicing valuer (CPV) certification.
