412 & 420 Eighth Avenue trades as prewar walk-up condominium stock in central Park Slope. It prices per square foot against other small conversion condominiums in the neighborhood, not against new construction or elevator buildings. Unit sizes sit in a narrow band, so floor, exposure and renovation state separate the prices. Through 2025, one- and two-bedroom condominium supply in prewar Park Slope stayed thin, and this building's sponsor releases a unit only when one comes free. Unit-level transaction history is maintained in The Roebling Research Library and shared with clients during diligence.

Every recorded sale
Sort any column; filter by unit or keyword. Prices are the recorded transfer amount at the NYC Department of Finance. Every sale sits in one of three states: counted in the building’s medians and trend; shown but excluded as a non-arms-length or nominal transfer; or shown and ⚑ flagged for review — a possible duplicate filing or an extreme $/sf outlier, held out of the statistics pending manual verification rather than allowed to move them.

Sources, exclusions and how these figures are computed
Sales sourced from NYC Department of Finance recorded transfers (BBL 3-01082-7502) and verified listing data. Apartment-level facts (line, condition, asking-price context) curated and cross-verified by The Roebling Team research desk. Not all transactions cross-verify with ACRIS records — sponsor and LLC purchases sometimes record at stipulated values rather than market price. Storage, parking, and commercial units are excluded from all figures. Floor- and line-level $/sf are time-controlled (each sale measured against the building’s going rate at the time of sale) and expressed at today’s pricing, so they isolate the floor or line premium rather than blend two decades of market movement.
