County assessor warns single-family values rising; early estimate shows about 20% average increase

Summary
County Assessor Dan Thomas presented preliminary reassessment data showing the average sale-price-to-assessment ratio climbing roughly 27.8% over 30 months, and early indications that single-family assessments may increase about 20% overall; the county plans to mail assessment notices in December and accept informal appeals through Jan. 31, 2026.
Gloucester County’s assessor told the Board of Supervisors that early market analysis for the 2026 reassessment shows strong residential price gains and a likely average assessment increase of about 20% for single-family properties.
Dan Thomas, county assessor, explained that Virginia law requires assessments to reflect market value as of a valuation date; for the 2026 reassessment that date is Jan. 1, 2026. He presented transaction data since the last reassessment and said the average ratio of sale price to current assessment climbed about 27.8% across a 30-month period, noting a 29% ratio in the first month of the third quarter. Thomas said waterfront and mobile-home properties showed especially strong sale-to-assessment increases, and that vacant and commercial parcels were tracking lower (around an 11% aggregate increase).
Why it matters: assessments directly affect taxable assessed value; increases in assessed values do not automatically raise taxes, but they inform the board’s equalization and tax-rate decisions during the budget process. Thomas emphasized assessment equalization is based on actual sales and market behavior; he told the board the assessor’s office would emphasize clear public communication about how market transactions drive assessment changes.
Practical details: Thomas said the office aims to mail assessment notices in early December and to accept informal appeals through Jan. 31, 2026; he proposed presenting updated statistics to the board in December or January after receiving third-quarter sales data. Board members asked for plain-language materials to accompany mailed notices to help property owners understand the reassessment and the separate process by which the board sets tax rates.
Public and board remarks noted the reassessment occurs amid regional housing-market shifts and the removal of tolls on nearby routes, which supervisors discussed earlier in the meeting as a possible future growth driver. Thomas also cautioned that while overall market value increases are projected at about 20% for taxable real estate, how any individual property fares will vary by neighborhood, property type, and condition.
