The line premium — where you sit sets the price
Same-3BR prices, time-controlled to today’s dollars, split by line — exposure, light, and layout vary stack to stack within a building.
Bar = today’s 3BR price for that line; right column = premium vs. an average 3BR.
The 3BR trajectory
Every recorded 3BR. The building trades thinly year to year, so the story is the long arc, not any single year: 3BRs traded at roughly $3.85M in 2007–10 and about $3.99M in recent sales.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-01391-0034) and verified listing data. Co-op apartments are priced by unit type (bedroom count) rather than per square foot — square footage isn’t officially recorded for co-ops, and room counts carry some agent-entry inconsistency, so bedroom type is the reliable spine. Non-arms-length transfers and storage/parking are excluded; line and floor premiums are time-controlled to today’s pricing. Where transaction volume is too thin to support a figure, none is shown.
Put this data to work.
Know what’s fair before you offer — we’ll show you where each line trades, the building’s discount-to-ask pattern, and where the value sits right now.
Price to the building’s real trajectory, not a guess — we’ll position your line against its true comps to maximize the outcome.
