Body Corporate issues alone are one reason to go for the block of land. Had a few units over time and not one escaped the frustration, lepathy and headaches of having to deal with or tring to get action from a body corporate. Oh, then you have very real issues such as crappy neighbouring tenants, body corp fees (like a leech sucking on your wallet), getting motions passed by the committee, trying to sell but the complex dragging you down.....do I need to even go on? I use to love units, but after waking up to the virtues of owning land, I saw how ignorant I was.
As for the Ippy block, what are you thinking - onsell or build and hold? How do the final build costs stack up against established property prices in the same area? All say Ippy's booming, but what has your research shown you? Investment or PPOR? As KPH said, what is your strategy?
