New Construction vs. Existing Homes: A Data-Driven Comparison Framework for Greater Boston Buyers

New construction vs. existing home decision requires analyzing seven key factors: (1) Total Cost (new costs 10-15% more upfront, but saves $200-$400/month in utilities and maintenance), (2) Warranties (new: 1-2 year systems, 10-year structural vs. existing: as-is condition), (3) Timeline (new: 8-12 months to build vs. existing: 30-60 days to close), (4) Customization (new: $20K-$100K+ in design choices vs. existing: renovation required), (5) Deferred Maintenance (new: $0 first 5 years vs. existing: $20K-$50K first 5 years), (6) Appreciation (comparable in established markets; new may appreciate faster in growth areas), (7) Negotiation (new: limited price negotiation, upgrades negotiable vs. existing: price/repairs negotiable). Neither is universally better; optimal choice depends on buyer priorities, risk tolerance, and financial situation.
