Banora Point is predominantly populated by retirees and elderly with multiple nursing homes and retirement villages. I asked the same question when I moved up from Sydney. Simply put, more people choose to pay a premium to live in what developers call a "modern Estate" which is in reality: narrow streets, no backyard and the next door neighbour's roof 1 meter away from theirs. Banora Point offers everything from budget housing to multi million dollar mansions. Demand for Banora Point is minimal which will always reflect house prices. This is why I bought here, quiet, beautiful, virtually no crime. Overall a very under rated suburb, of which I took full advantage of.
