Property Tax Appeal
Union County Residential Appraisal & Property Tax Appeal — Blairsville, Lake Nottely
Independent market evidence for Union County homeowners appealing their Annual Notice of Assessment — Blairsville and the mountain and lake communities near Brasstown Bald.
Appeal Window: Union County property owners generally have 45 days from the date on their Annual Notice of Assessment to file an appeal. This is based on standard Georgia procedure — always verify the exact deadline printed on your own notice and file with Union County Board of Tax Assessors — unioncountyga.gov before ordering an appraisal.
Union County's market spans Blairsville's mountain-town core and the surrounding second-home and vacation-cabin communities near Lake Nottely and Brasstown Bald, Georgia's highest point. When your notice doesn't reflect what your specific property would actually sell for, an independent appraisal gives your appeal organized, defensible market evidence.
Understanding Your Notice
Understanding Your Union County Assessment
Who Sets Your Value
The Union County Board of Tax Assessors determines taxability, fair market value, and equalization — and is also delegated to receive tax returns and process homestead exemptions, a function often handled elsewhere by the Tax Commissioner.
Like every Georgia county, Union County assesses residential property at 40% of fair market value for tax purposes. An appeal challenges the county's opinion of fair market value — exactly what an independent appraisal is built to evaluate.
Your Tax Bill vs. Your Assessment
Your final bill combines county and school millage, plus any homestead exemption filed. An independent appraisal speaks to fair market value, not the tax calculation.
When It May Help
Common Reasons Union County Assessments Get Questioned
The comparable sales behind your Union County assessment may be pulled from a different sub-market than your property's.
Deferred maintenance or property condition issues aren't reflected in the county's file.
A feature, addition, or upgrade assumed by the county doesn't match what's actually on the property.
This year's increase is larger than what recent Union County sales data would support.
Local Appeal Process
How to Appeal in Union County
Union County property owners appealing the fair market value of real property must submit an appeal to the Board of Tax Assessors, postmarked within 45 days of the mailing date on the notice of assessment. The office is located at 65 Courthouse Street, Suite 4, Blairsville, GA (706-439-6012).
You can typically file through the Union County Ad Valorem Tax page. Georgia Valuation Source provides independent appraisal evidence for your case — we do not file appeals or provide legal representation.
Board of Equalization
Your appeal is reviewed by the Board of Tax Assessors first; if unresolved, it's forwarded for a formal hearing.
Hearing Officer
Available only for non-homestead real property valued at $500,000 or more — relevant to a number of lake and mountain-view properties.
Arbitration
Requires a certified appraisal submitted with your appeal; escalates to binding arbitration via Superior Court if rejected.
After You File
The Board of Tax Assessors mails annual assessment notices and oversees the property tax appeal process from the same office.

Building Your Case
What Evidence Matters
Recent closed sales of genuinely comparable homes — similar size, age, condition, and location — with the differences between those homes and yours accounted for individually.
Photographs and a description of any condition issues, deferred maintenance, or functional problems the county's mass-appraisal model would not have observed.
Documentation of the property's physical characteristics (square footage, lot size, room count, systems age) if it differs from county records.
A clear, professionally organized opinion of value — not just a lower number, but the market evidence and reasoning behind it.

Residential Appraisal Considerations in Union County
Lake Nottely waterfront and mountain-view premiums: Lake Nottely waterfront and elevated mountain-view lots command a distinct premium and require a separate comparable pool from valley-floor and non-view properties near Blairsville.
Second-home and retiree-driven demand: An 84.4% owner-occupied rate combined with 13.1% population growth since 2020 points to strong retiree and second-home in-migration, a different demand driver than the job-growth-led markets in metro-adjacent counties.
Mountain terrain and septic/well constraints: Steep Blue Ridge terrain limits buildable lots and often requires engineered septic systems, which can materially affect land value and development cost outside the Blairsville valley floor.

Local Market Considerations
Union County Market Diversity
Lake Nottely waterfront homes and mountain-view cabins near Brasstown Bald carry very different comparable-sale patterns than Blairsville's in-town properties. A single countywide model can misstate value for an individual property outside its typical calibration range.
