I have just purchased a CF+/neutral property in Karatha WA. It doesnt quite fit into your criteria but I think the reasoning behind my purchase has merit.
My near new 3 BY 2 unit cost $625k and I have just let it to a Govt tenant at $1200p/week for 5 years with annual rent reviews to market with the base set at $1200 p/week.
To my mind, the CG may be less than I could expect in an area of your liking, however, I will not put a cent of my own money towards this IP over the next 5 years, in fact it may just fund my next purchase with the leftover cashflow. I expect some CG over this period too.
There are some properties in the South Hedland area of WA that you would get at less than 500k, and they will be CF+ or at least neutral, with tenants lining up to get them for good lease terms.
I would be interested to hear what "Dazzling" has to say about this theory. I am quite new to the IP arena and have 3 properties in my protfolio that is at this time CF+. I have around $1m equity with good servicability and consider these areas pretty solid with the oil/gas and minerals industries well positioned for the long term and with much growth planned. Seems an acceptable risk level to me, you may disagree.??
