Summary answer: Herndon's numbers genuinely vary — one measure showed the median sale price up 30.7% year-over-year in early 2025, while more recent 2026 data shows list prices actually down 5-6% year-over-year in some readings. Given this genuine volatility, checking real, recent comparables matters more than a single percentage.
I'm Johnny with JQ Real Estate. Let me explain why the right number depends on the specific listing.
What the data actually shows
| Measure | Reading |
|---|---|
| Redfin (Feb 2025) | $660,000, +30.7% YoY |
| Movoto (Jun 2026, list price) | $679K, -5% YoY |
| Smover (12-mo through Aug 2026, sold) | $700,000 |
Why this volatility genuinely matters for your offer
A sharp 2025 spike followed by 2026 cooling suggests the market found a new, more sustainable level after an unsustainable run-up — this is worth understanding before you assume last year's percentages still apply. Your agent pulling truly recent, closed comparables (not list prices, which can run ahead of or behind actual sale prices) gives you the most reliable read.
How to figure out the real target number
- Pull actual recent comparable sales in the specific neighborhood or building
- Check days on market and price history for the specific listing
Why working with a local agent matters here specifically
Herndon's genuine mix of neighborhoods — from the historic downtown to newer development near Rivana Town Center — means listing activity can vary block by block. An agent who's actively watching this specific market day to day can tell you within hours whether a listing is drawing real interest, rather than relying on lagging citywide statistics that may not reflect what's happening on your target street right now.

One more practical tip: ask your agent to set up same-day showing alerts for your target neighborhoods, so you're never the last to know about a promising new listing.
