Deppro are QLD based. I was very happy with what they did for me in QLD. However, their two Sydney reports were the worst and second worst reports my accountant has ever seen. E.g. the cost of building will not cover half the cost of bricks. 80% land value for a unit in a block of 60. All attempts to discuss their reports with them revealed that they did not understand what quantity surveying was.
Would recommend them in QLD, but not anywhere else.
