Aiken's housing runs the highest of comparable South Carolina markets in this project's research pass (Zillow's $246,547 typical value, with a genuinely wide, even internally inconsistent, spread across other sources reaching as high as $320,000), reflecting a real, comparatively more affluent character shaped by its equestrian estates and federal-scientist workforce tied to the Savannah River Site.
North Augusta: A Real Property-Tax Advantage Over Augusta, Georgia
North Augusta shows a real, disclosed measurement gap in its own housing data: median sold/list prices ran $338,000-$340,950 across three 2026 citations, while Zillow's typical-home-value (ZHVI) measure read considerably lower at $235,945. The clearer, better-documented advantage here is property tax: North Augusta's own effective rate (0.41%) is the lowest in Aiken County, built on South Carolina's favorable 4%-owner-occupied assessment structure -- a real, structural difference from Georgia's property-tax approach that a single relocation-blog source (disclosed as low-confidence) estimates saves North Augusta buyers roughly $1,200-$2,800 annually versus an equivalent Columbia County, Georgia property.
A Genuine, Current Cross-Border Tax-Rate Convergence
Georgia's flat individual income tax rate dropped from 5.19% to 4.99% for tax years beginning January 1, 2026 -- genuinely close to South Carolina's own Act 110 top rate (5.21%, above $30,000 of taxable income), but the two states' structures differ meaningfully: Georgia taxes flat from the first dollar, while South Carolina taxes only the first $30,000 at a much lower 1.99% for every filer, a real, disclosed structural advantage for South Carolina-side buyers at most income levels.
Key takeaways
- Aiken carries this region's higher, more equestrian-estate-driven housing prices; North Augusta runs more moderate, with a real disclosed measurement gap across sources.
- North Augusta's 0.41% effective property tax rate -- the lowest in Aiken County -- provides a real, documented advantage over comparable Georgia-side property.
- Georgia's 2026 flat-tax cut (to 4.99%) narrowed, but didn't eliminate, South Carolina's structural income-tax advantage for most filers in this cross-border region.
