We leased 53 properties last month best month in 14 years of operation (we have averaged 40-45 per month this year/ last 18 months) should add 300 or so properties this year which is huge. We are the largest company in the area but ultimately we are dominating every other agent through our systems. I work in the fastest growing corridor in Australia or perhaps 2nd or 3rs these days but you get the idea lot of new houses & construction.
Rents are ok not as high as they were but its all relative.
It's really up to the OP some people buy for the capital growth, others tax breaks or as a revenue stream depends on your situation and where your at in life.
