A little about us

Not all investment property tax depreciation schedules are built the same. They should be but the reality is, like many things in the property world, all is not as it seems. The devil is in the details—and the details are everywhere. But relax, at Washington Brown we take care of every last one.

Established in 1978, Washington Brown is one of Australia’s oldest and most respected quantity surveying organisations.

Each year, we prepare more than 13,500 reports, delivering $1.5 billion in depreciation savings.

What our corporate and individual clients say about Washington Brown and its Director Tyron Hyde…

Harry Triguboff

“I made up my mind to work with Tyron when I saw him. I never went to another quantity surveyor. And I never regretted it.”

Harry Triguboff - Founder and Managing Director, Meriton
Pam Walkley

“If there is some detail about property depreciation that Tyron Hyde does not know I have yet to find it… his deep knowledge of how to take full advantage of the depreciation rules helps investors make the highest possible returns from their real estate investments.”

Pam Walkley - Editor in Chief, Money magazine
Lesley Williams

“I chose Washington Brown to do my tax depreciation because I was buying interstate and needed a nationwide company. My property was built in 2005 and the first year deduction was $10,000 so I was really happy. I would definitely recommend Washington Brown to other property investors. They are really efficient and the whole process was seamless.”

Lesley Williams - Property Investor
Dipal Prajapati

“In my opinion, Washington Brown is one of the top tax depreciation companies. In the first year for a brand new property off the plan, I received a $12,000 tax depreciation claim. I also have an older property and I received around $7000 for the first year, which was great for me in my tax return.”

Dipal Prajapati - Property Investor
Veronica Morgan

“I’ve had Washington Brown do depreciation schedules for all of my investment properties and contrary to what a lot of people think, you just don’t get one done when you buy something brand new. I don’t buy modern properties and every time I do some improvements, I also get a new depreciation schedule so it’s been fabulous from a tax perspective.”

Veronica Morgan - Principal, Good Deeds Property Buyers
Leon Gu

“I knew Washington Brown had been around for a long time and had a good reputation for its tax depreciation services so I thought I would give them a try. I own an old property - built in the 1960s. My first year deduction was about $4000. The process was smooth and I received a lot of follow-up emails so it was good.”

Leon Gu - Property Investor
