How to read this: The premium jumps sharply between floors 1–5 and 6–15 (noise, overlooking relief), then flattens between floors 15–30 as the view improvement is marginal. A buyer targeting floor 14 pays only $100 PSF more than floor 5 — about $120,000 on a 1,200 sqft unit — but avoids the noise and privacy issues of the low floors. Floor 25 adds another $80 PSF over floor 15 for incrementally better views. Whether that extra $96,000 is worth it depends on the individual buyer's priorities, but the data shows it is not capturing proportionally more rental income.
