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 Manassas readings (+13.9% in one measure, -1.6% in another citywide figure), automated estimates here can be more volatile than usual.

Reason What's Happening
