I just calculated mine, it's sitting at 65%. That means on average, 35% of all my rental income goes to repairs, agency fees etc (excl. interest). A further breakdown: Worse is 57% - my only apartment - due to...you guessed it, body corporate fees...which is funny considering gross yield is a very reasonable 6% (lesson here is be careful about using a gross yield calc, it can be very misleading) Best is 73% - a regular run of the mill house that hasn't needed much maintenance in recent years I'm curious whether anyone else has run their numbers before? Note that I've disregarded the first few months of any recently purchased properties so that upfront renovation / holding costs don't skew the numbers.
