Why the full dataset matters
These 4 records are a sample. Averages hide the range — a 25㎡ studio and a 90㎡ family unit in the same area have very different price points. Building age changes everything too.
The full dataset lets you filter by size, age, and exact location to find transactions that match your criteria — not just the area average.
