The short version
- If you bought your home for less than the county's fair market value (FMV), that purchase price is some of the strongest appeal evidence there is.
- A recent, ordinary, arm's-length purchase is — almost by definition — what the home is worth. A county FMV well above it is hard to defend.
- Georgia's assessed value is 40% of FMV. You appeal the FMV, and the deadline is 45 days from the date on your assessment notice.
- Two quick first moves for every new owner: file your homestead exemption (you don't inherit the seller's), and check whether your FMV matches what you paid.
You closed, you got the keys, and a few months later a Notice of Assessment shows up with the county's idea of what your home is worth. For a lot of new Georgia homeowners, that number is higher than what they just paid for the place — which is a little absurd when you think about it. You bought it on the open market. That price is the market. And it might be the best appeal evidence you'll ever have.
This guide is the new-owner version of the appeal process: why fresh buyers get over-assessed, why your purchase price carries so much weight, and the two simple things to do right after closing.
Why new homeowners get over-assessed
It's rarely anything personal — it's how mass appraisal works. Counties value enormous numbers of parcels using models and trends rather than walking through each home. A few things make new buyers especially likely to land above their real value:
- The county's number can lag — or lead — the market. Assessed values are set on a calendar that doesn't match the day you closed, so they don't automatically reflect your actual sale price.
- You may have negotiated below the asking price or the model's estimate. The county's automated value doesn't know about the repairs you talked the seller down over.
- Record errors carry forward. If the prior owner's record overstates square footage, an extra bath, or a finished basement, you inherit that inflated number until someone corrects it.
- A sale itself can trigger a re-look. A transaction can prompt the county to revisit the value, and the new figure may overshoot what you actually paid.
Why your purchase price is powerful evidence
Here's the core of it. Most appeals are won with comparable sales — other homes like yours that sold nearby for less than your assessment. A recent purchase of your own home is even better than a comp: it's not a stand-in for your property's value, it is your property's value, established by a real buyer and a real seller in an open transaction.
When a home changes hands in an ordinary, arm's-length sale — meaning a normal deal between unrelated parties, each acting in their own interest, with the home exposed to the market — the agreed price is about as clean a measure of fair market value as exists. So if the county says your home is worth $620,000 and you just bought it for $560,000 in a standard sale, you're not arguing an opinion. You're pointing at what the market already decided.
A recent, arm's-length purchase price below the county's FMV is one of the most persuasive cases a homeowner can bring. Keep your closing documents — the settlement statement and purchase contract — handy. That gap between what you paid and what the county claims is, quite literally, your case.
When the purchase price doesn't carry as much weight
We'd be doing the opposite of our job if we pretended every sale is a slam dunk. A purchase price is weaker evidence when the sale wasn't a normal open-market deal. The county may give it less weight if:
- It was a foreclosure, short sale, or bank-owned (REO) purchase.
- You bought from family or another related party (not arm's-length).
- It was an estate or distressed sale, or a quick off-market deal that never really hit the open market.
- You bought a fixer-upper cheaply and then renovated — improvements after purchase can legitimately raise the value.
None of these automatically kill an appeal, but they change the analysis. If your purchase was an ordinary sale at a normal price, you're in the strong lane. If it wasn't, comps and record corrections may do more of the work.

Two things every new Georgia homeowner should do
1. File your homestead exemption
This is the one almost everyone forgets. The homestead exemption lowers the taxable value of the home you live in — but you don't inherit the previous owner's exemption when you buy. You have to file your own, as the new owner-occupant, for the home to be treated as your homestead. It's usually a once-and-done filing with your county, and for owner-occupants it's the easiest tax saving there is. We walk through it in our Georgia homestead exemption guide, including the newer HB 581 floating cap.
2. Compare the county's FMV to what you paid
Pull up your assessment and look at the fair market value the county assigned. Set it next to your purchase price:
- County FMV well above your purchase price, and it was a normal sale? You likely have a strong case worth filing.
- County FMV roughly equal to or below what you paid? Your assessment is probably fair — and we'll say so. That's not bad news; it means you're not overpaying.
While you're in the record, double-check the basics — square footage, bed/bath count, lot size, year built. New owners catch inherited errors all the time, and a factual error is one of the cleanest corrections there is.
Mind the deadline
Strong evidence only helps if you file in time. In Georgia you have 45 days from the date printed on your Notice of Assessment to appeal — in Fulton County, with notices mailing around mid-June, that usually means a late-July deadline. Miss it and you generally lose the chance to appeal that year's value, however good your purchase-price case is. If you're a recent buyer, don't file your closing folder away and forget it — watch for that notice and check the date the moment it lands. (Details in our guide to the Fulton County 45-day appeal window.)
In Georgia, winning an appeal doesn't just fix one year. A successful appeal generally triggers a multi-year freeze on your value — so a new owner who corrects an inflated assessment now can lock in the lower number for years. See our guide to the 3-year property tax freeze.
The honest bottom line for new buyers
If you just bought in Georgia and paid less than the county thinks your home is worth, you may be in the best appeal position there is — and the clock is the only thing working against you. The full process is laid out in our cornerstone guide on how to appeal a Fulton County assessment. And if you'd rather just find out whether your purchase price actually beats the county's number, that's a free, no-obligation check. If your assessment looks fair, we'll tell you that too — we only take cases we believe we can win, so being straight with you is the whole point.
New homeowner appeal FAQ
Can I appeal my property taxes right after buying a home?
Yes. You can appeal the year's assessment once you receive your Notice of Assessment, and a recent purchase is often strong evidence. The key is timing: you have 45 days from the date on the notice to file, so watch for it after closing and act within that window.
Is my purchase price good evidence for a tax appeal?
Usually, yes — and often it's the best evidence available. A recent, arm's-length purchase (a normal open-market sale between unrelated parties) establishes what the home is actually worth. If the county's fair market value sits well above what you paid, that gap is a strong basis for an appeal. The price carries less weight if the sale was a foreclosure, a short sale, a purchase from family, or a distressed deal.
Do I keep the previous owner's homestead exemption when I buy?
No. The homestead exemption does not transfer to you automatically. As the new owner-occupant, you must file for your own homestead exemption with the county for the home to be treated as your primary residence. It's one of the first things new homeowners should do, because it lowers your taxable value going forward.
What if the county's value is the same as what I paid?
Then your assessment is probably fair, and an appeal is unlikely to lower it. That's genuinely good news — it means you're not overpaying. We'd rather tell you the number looks right than file a long shot, which is also why an honest read up front is worth getting before you spend time on an appeal.
