Has anyone heard of the 4 so called boom suburbs in Sydney? I heard they were Picnic Point, Balmain. Roseville and Menai. Apparently prices are set to boom there? I dunno but i always like to do my homework first as i did with a site i thought was illegal called http://www.dumptheagent.com.au for home buyers so they can avoid paying agents commission. Can anyone confirm on deny these so called 'secret' suburbs? Thanks. Trudy.
