The $5 Million Acre: Understanding Residential Land Prices in Greater Boston

Residential land in Greater Boston's inner suburbs commands $3-10+ million per acre, with Cambridge and Brookline at the top. Land values roughly doubled from 2010-2020 and have plateaued at record highs in 2024-2025. Going forward, expect continued strength with low-to-moderate appreciation (2% annually) as demand stays high but affordability constraints and new supply temper growth.
