I had my 3 bedroom average home evaluated and an offer made. It was, and still meets with the comparables in my neighborhood, which hasn't dropped too much since the time of evaluation. The problem was, and still is, finding a replacement home (upgrade) that would be a better fit but not over price our point. The home prices are still strong in Henderson, NV, resale still looks pretty good, and the price drop of a few thousand is also seasonal in many markets. Zillow will probably do great in the larger transient cities where there is a lot of movement.
