Henry County is Atlanta's southside growth story â a county that has absorbed tens of thousands of new residents as buyers priced out of closer-in Atlanta counties moved south along I-75. McDonough, Stockbridge, and Locust Grove have emerged as substantial suburban communities. The Henry County Board of Tax Assessors values all real property â and the same mass-appraisal challenges that affect faster-growing counties create consistent over-assessment opportunities here. Georgia law gives every Henry County homeowner 45 days to appeal.
How Henry County Values Your Property
The Henry County Board of Tax Assessors values all Henry County real property at 40% of estimated fair market value as of January 1st. Henry County's growth has been driven by I-75 corridor access and lower land prices relative to closer-in Atlanta suburbs. This creates a market with significant variation in home quality, age, and condition across otherwise similar-sized lots â exactly the conditions where mass-appraisal models are most prone to error.

Henry County Market Context for 2026
Henry County experienced strong appreciation from 2020 through 2022 as southside Atlanta emerged as a destination for buyers seeking more space at accessible price points. Since the market peak, rising mortgage rates have cooled demand and increased active inventory. New construction has continued, creating supply competition that has kept resale prices under pressure in some submarkets.
