22 Copperfield Ln, Old Westbury, NY 11568, USA

The subject is inferred to be a 5-bed, ~6,500 sq ft luxury single-family home on ~2 acres in Old Westbury, comparable to a nearby Old Westbury property that sold for $4,000,000 on 2/16/2024 at roughly 5,530 sq ft and similar high-end finishes.[1] Adjusting for the subject's slightly larger estimated square footage, similar lot size, and general parity in quality to other luxury Old Westbury estates, a range of $3.5M–$4.3M is reasonable, centered around ~$3.9M. Active nearby luxury listings such as 22 Terrace Ct at $7.95M and 23 Old Westbury Rd at $14.95M represent larger or ultra-luxury estates and set an upper market ceiling rather than direct comparables.[4][5] More modest listings like 32 Valley Rd at ~$1.9M are smaller houses on smaller lots and indicate the lower bound of the Old Westbury single-family market.[6]
