I pay 8% plus gst, many in the area charge 8.5%. Most are negotiable as many of the fees/additional fees are just a try on. I make it clear I consider these B.S., and have had many grin in acknowledgement. I don't pay P&P or any other excuse for monthly/annual fess, or lease renewal. Tribunal (if ever needed) are usually based on an hourly rate - just make sure not excessive. I find the franchise agents charge the most, some wont budge on price. I notice there is no mention of leasing fee (for finding tenant), usually 1 weeks rent +gst, anything more falls into the B.S. pile.
Some will charge for arranging/overseeing renovation (different to repairs) which is not unreasonable for the time taken considering what it saves you, and I know some strata managers charge for more than 3 quotes which is not unreasonable either assuming they are not getting stupid quotes from unrealistic tradies. I often ring around myself to get my own quotes or estimate of cost.
Do your sums on management fee % versus P&P as sometimes you are better off arguing for a smaller % and pay the monthly fee, other times pay the % but haggle over removal of P&P. Some agents will negotiate on one but not the other.
ie .5% of $400pw = $2.00. (52 x $2.00 = $104.00) Better to agree to $5.50 P&P p/m ($5.50 x 12 = $66.00) and argue for 8% rather than 8.5%.
When signing your management agreement make sure that what was negotiated is represented in the agreement. I have seen honest errors made which needed correcting, but I know others who have later discovered that their agreement is not as per initially negotiated - and too late to change.
