Pricing a unit at 50 Watertown St
In a building like this, the comps that matter are the ones upstairs and down the hall — not the town-wide condo median. With 71 units and 15 sales in five years, there's usually a recent in-building comp to anchor from, and the differences from there come down to floor, exposure, parking, and condition.
If you own here, the table above is the raw material. A proper valuation adjusts each of those sales for how your unit compares — which is exactly what I do in a free value report, built from this building's actual closed sales.
