What most affects the actual return in Washington, D.C.?

Recency and condition. In Roots' model, work under 2 years old counts fully toward resale value, then depreciates toward ~20% after 10 years. A home with a documented maintenance record also typically sells closer to asking. Market conditions in the South Atlantic division set the regional baseline.

Where do these numbers come from?

Roots calibrates the national baseline for a basement remodel against the 2025 Cost vs. Value Report (Zonda), then applies a South Atlantic-division adjustment derived from division-level averages in the 2024 Cost vs. Value Report, plus the model's own age and condition factors. Figures are modeled estimates, not appraisals.

The South Atlantic market

The South Atlantic, running from the D.C. suburbs down through the Carolinas, Georgia, and Florida, has been one of the country's strongest in-migration corridors, and steady buyer demand pushes renovation returns above the national average. The housing stock skews newer than the Northeast, so buyers often expect modern layouts and finishes as the baseline.

With so much newer construction nearby, an updated interior is often what keeps an older home competitive in this market.
