How the Showdown works

Each matchup compares two projects on the metrics that actually decide the choice — installed cost (state-adjusted), appraisal uplift at resale, timeline, disruption, lifetime cost, and the buyer / appraiser behaviors that tilt the verdict. Numbers are sourced from the 2026 Remodeling Magazine Cost vs. Value Report, NAR Remodeling Impact Report, NAHB Cost Survey, Realtor.com 2025 buyer survey, and HavenCostGuide's 11-calculator cost engine.

ROI ranges are reported wide because they vary by state, finish tier, and hold period. Top of range = mid-quality work in tight inventory metros; bottom of range = budget work in soft markets. Every matchup links to the relevant cost calculator so you can run your own numbers.
