"I have had the pleasure to engage Patrick on behalf of my investor Clients to obtain depreciation reports for newly acquired investment properties. Patrick was always willing to go the extra mile by providing advice even before being engaged which put my clients at ease and enabled them to make an informed purchase decision. I would highly recommend Patrick as a QS to anyone looking to maximise their tax deductions.
