Summary answer: A Zillow estimate drop usually reflects a recalculation based on nearby comparable sales, not a genuine decline in your home's actual value. Given real variance between recent Annandale readings (+0.6% Zillow typical value vs. +3.5%-3.7% in other measures), automated estimates here can be more volatile than usual.
I'm Johnny with JQ Real Estate. Let me explain what's likely actually happening.
Common reasons a Zestimate drops
| Reason | What's Happening |
|---|---|
| A nearby distressed or below-market sale | Pulls down the algorithm's comp pool temporarily |
| Data source variance | Different sources have shown meaningfully different Annandale trend readings recently |
